|“||I find that I do some of my best work under intense terror.||”|
— Reid in "Damaged"
Dr. Spencer Reid is a Supervisory Special Agent with the BAU. He is hailed as a genius and an autodidact.
Reid graduated from high school at the age of twelve. In his youth, his father William left him and his mother Diana as he could no longer deal with her paranoid schizophrenia, among other things. Reid once mentioned that he was a victim of bullying in school where he was stripped naked and tied to a goalpost in front of other students. After waiting for all the other teenagers to leave, he walked home, only to find that his mother had not noticed he was so late to return because she had been having one of her schizophrenic episodes. Reid grew up learning nearly everything he knows from books, with his mother (a college professor of 15th-century literature) often reading to him. Still, Reid knew that the way his mother was living wasn't healthy.
When he was eighteen, he had Diana placed in a mental institution. Until Season Twelve, she resided in that same mental institution and Reid had stated that he sent letters to Diana every day because of the guilt he felt for not visiting her. Reid is also worried about the fact that his mother's illness can be passed on genetically; he once told Morgan that "I know what it's like to be afraid of your own mind."
Reid has an eidetic memory, meaning that he can remember an exceedingly large amount of information with extraordinary detail. This, however, only definitely applies to information gathered visually (especially things he's read, as implied with the word eidetic). His ability to retain auditory information, however, has been rather inconsistent, as evident when he once noted he could not remember "that new tech girl's name" ("Tabula Rasa"), but has been able to perfectly recite speech he hears, even when it was in a completely different language of which he didn't speak a word ("Corazón").
Reid is socially awkward. He often fixates on things (prompting Morgan and other team members to have to tell him to be quiet), and misses social cues at times (for example, unknowingly changing the subject of a conversation). The unsub in "Broken Mirror" noted this, and Gubler stated in an interview in the show's second season "[Reid]'s an eccentric genius, with hints of Schizophrenia and minor autism, Asperger's Syndrome. Reid is 36 years old with three Ph.Ds and one cannot usually achieve that without some form of autism."
Gubler has also commented on the differences between Reid and similarly odd character Penelope Garcia: "She represents everything he is not, she is very tech oriented and I would like to imagine he is more like 1920s smart, books and reading etc." Kirsten Vangsness agreed, adding Garcia is more extroverted and available emotionally, whereas Reid struggles with his emotions. Reid is a technophobe and does not use either email or the new iPads. Gubler tweeted that Reid is also germaphobic. In general, Reid dislikes shaking hands and shows adverse reactions when touched by strangers. It is speculated the character may also have slight obsessive-compulsive disorder, particularly from a scene in "Out of the Light" where Morgan slightly moves an item in the home of a suspect who suffers from it, and Reid immediately places it back to its previous spot.
Reid turned 24 in the episode "Plain Sight". He also asked JJ out on a date, after being handed tickets to a football game by Gideon, who tells Reid that JJ is a big fan of football. In the following episode, Reid only said that the date was "top secret" and it was never mentioned again.
In "L.D.S.K.", despite failing his gun qualification, Reid still manages to deliver a fatal shot to the head of Phillip Dowd (with Hotch's backup weapon, a Glock 26); thus saving himself, Hotch, and a room full of hostages. He later joked that he was "aiming for his leg". Hotch is so proud of Reid he lets him keep the gun. It is not clear whether or not he kept the weapon as he is never seen using it again.
In "Derailed", Reid reveals that he is capable of impressive sleight-of-hand magic tricks, which he uses to trick the deranged hostage-taker. He then shows remarkable insight into the mind of the delusional man, successfully distracting him to protect the hostages. After Elle Greenaway admits that Reid saved her life, she asks about how he gained such insight, implying that Reid may have some personal experience with mental illness. Reid explains that he was just pretending, pats Elle on the knee, and walks away; leaving Elle and the audience wondering if he is hiding something.
In "Somebody's Watching", Reid garnered the affection of Hollywood starlet Lila Archer, who was being stalked by an unsub who killed people to further Lila's career. Lila gives Reid what may have been his first kiss. It is unclear whether Reid tried to pursue the relationship further, but JJ teased him about it briefly in the Season Five episode "The Performer", asking if he still talked to Lila. Reid declined to answer and quickly changed the subject back to the current case.
In "The Fisher King, Part 2", Reid reveals to the rest of the team that his mother is "a paranoid schizophrenic who wouldn't remember to eat without being properly medicated and supervised". He mentions to Garcia that schizophrenia is passed on genetically, something he is evidently worried about.
In "Aftermath", Reid seems to be the only team member who notices Elle's odd behavior, and confronts her; he gets her to open up to him but it does not stop her from spiraling out of control. Reid later blames himself for not having done more to help her.
While being held hostage by serial killer Tobias Hankel, Reid was repeatedly tortured and forcibly injected with Dilaudid, which caused hallucinations of his past and he became addicted. He had a near death experience when he went into a seizure where he saw shadowy figures and a bright light (and, as he later pointed out to Morgan, it couldn't be like other cases where these visions are just doctors in the emergency room). Reid was forced to kill for a second time using the revolver that his captor used to torment him. Reid's addiction was noticed by Hotch and Gideon over time, as well as an old friend of Reid's in New Orleans ("Jones"). He has since become clean; in Elephant's Memory, he attended a support group (called The Beltway Clean Cops) meeting for addicts in law enforcement. He said he'd been experiencing cravings recently and spoke of the young man shot in front of him (in "3rd Life") before being interrupted by multiple calls summoning him to work. He was surprised to find one of his superiors attending the same meeting. The older agent, named "John", loaned Reid his one-year sobriety coin, making Reid promise that he would return once he earned his own. He is still very particular about staying clean, as seen in Amplification when he strictly refused to take any narcotic painkillers after being infected by anthrax.
When Gideon does not show up at work and fails to answer phone calls ("In Name and Blood"), Reid drives out to Gideon's cabin in his own car. Upon arrival, he finds a note addressed only to him explaining why Gideon chose to leave the BAU. Later, Reid explains to Prentiss that his father did the same thing when he abandoned Reid and Diana. Prentiss later exclaims to Reid that there was a reason that he left the note only to Reid to find and not the team.
In the episode "Damaged", he managed to save himself and Hotch from Chester Hardwick (who intended to kill them as a way to evade the execution of his death sentence) by giving a thirteen minute lecture on the medical explanations for Chester's condition and behavior. When the situation had been diffused, he stated that he didn't know if the profile was accurate, thus revealing it had been improvised on the spot using his encyclopedic knowledge. He also stated that he does some of his best work when under 'intense terror'.
In the episode "Elephant's Memory", Spencer received a medallion from another superior agent only named John as his previous addiction to Dilaudid was giving him cravings since his previous witness to the murder of Ryan Phillips by the hands of Jack Vaughn, encouraging Spencer to strengthen his resolve and return the medallion once he had reached the one year mark. Later in the same episode, Spencer lets some aloud some outbursts towards Morgan and a Texas PD officer handling the case in somewhat of a defense towards Owen Savage. It's revealed in a later scene that he identified with Owen, and was also bullied in high school by being lured towards the football field and forced to strip naked and tied to the football pole. Morgan is the only person he told this story to.
In the Season Four episode "Minimal Loss", Prentiss and Reid went undercover as "child interview specialists" to determine if the polygamist cult leader was sexually abusing young girls. Prentiss took a severe beating in order to protect Reid, causing him to feel guilty about her having to protect him. In "The Instincts", a young boy disappears, and it leads Reid to some questions about his own past. He visits his mother, who inadvertently helps him solve the case.
In "Memoriam", Reid reunites with his estranged father, William Reid, whom he hasn't seen in 17 years. It is not a happy reunion, as Reid is still very angry and suspects his father of murder. However, William is eventually cleared of any suspicion. At the end of the episode, Reid meets JJ's newborn son, Henry, and JJ asks him to be Henry's godfather.
In "Conflicted", Reid correctly profiles the victim/murderer, Adam/Amanda, and successfully talks him down from murdering his abuser, his step-father. Later he is seen reflecting on his actions as Morgan confronts him, prompting Reid to correlate Adam's relationship with dissociative personality with that of his previous kidnapper Tobias Hankel. Reid doubts his abilities, prompting Morgan to tell him that sometimes they can't save everyone.
In "52 Pickup", Reid impressed a female bartender named Austin while investigating a serial killer. On Morgan's advice (who told him "chicks dig magic"), he performed an impressive illusion with a pen and a flier showing a police sketch of the unsub. When she asked for his number, he told her she already had it behind her barrette, which she pulled out of her hair. The bartender would later call him and ask him out, though nothing appears to have come of it.
In "Nameless, Faceless", Reid is shot in the leg by an unsub while protecting a doctor whom the killer had targeted. It is a non-life-threatening wound, and Reid tells the doctor to treat the unsub instead of him. In the next episode, "Haunted", he carried crutches. Because of his injury, he stayed and worked from Quantico with Garcia in "Reckoner". Later in the season, he moved on to use a cane and continued doing so until the episode "The Uncanny Valley".
In "100", Reid manages to figure out that George Foyet is using the alias "Peter Rhea," which is an anagram of "The Reaper". The team finds out Rhea's address and storms his apartment, only to find that Foyet had posted an Internet alert on the name Peter Rhea (to alert him if the name was ever investigated) and has disappeared.
In "The Uncanny Valley", Reid returns to the public park where he used to play chess with the locals. A boy that knows Reid mentions that he used to come more often. Reid says that he used to play with an old friend who quit, Gideon, though he doesn't mention his name, just that he knows why he did quit. He was doing the same theme over and over and expecting a different outcome, yet it was all the same, the same definition of insanity. Spencer later deduces that the unsub, Samantha Malcolm, had been the subject of sexual abuse and electro shock therapy, trapping her mind in a broken childlike state at the hands of her father, Dr. Arthur Malcolm. He finds Samantha amongst 3 victims and manages to talk her down and cooperate with authorities without any violence.
In "Risky Business", Prentiss shows Reid a star puzzle set that she proclaimed impossible to piece back together. Reid then placed it together within seconds, prompting her to exclaim jokingly that there's a lot to hate about Reid, Morgan, Rossi, and Garcia then chimed in to throw their opinions never to play Chess, Poker, or Go with Spencer.
In "...A Thousand Words", Reid is tasked to originally work on the tattoos of the unsub and decifer its meaning but ends up working the journals as he can read much much faster than the rest of the team. Towards the end of the episode, Prentiss is seen beating him in poker.
In "J.J.", Reid takes antacids from Prentiss's desk, something that she notices; she asks, "Again with the dairy?" Reid replies with, "I can't help it, I love dairy". This implies that he is lactose-intolerant but, in retrospect, could have been a cover for his headaches that were revealed later. On the jet, he is later shown to be feeling sick and went into the bathroom. When he comes out, he is wiping his mouth as if he had been vomiting.
In "25 to Life", Reid appears to be rather disheveled. His shirt is partially un-tucked, his hair was unkempt, he reads very slowly, and he is much quieter and more subdued than he had been in past seasons. The rest of the team seems oblivious to these signs.
In "Corazón", Reid is revealed to be suffering from intense headaches, and possibly hallucinatory episodes, while working the case. Throughout the episode, Julio Ruiz, a religious leader, tells Reid that he's carrying the deaths and souls of people along with him and that they're still with him and is affecting his own soul. In the end of the episode, he goes to see a doctor, who finds nothing physically wrong with him, suggesting it may be a psychosomatic disorder. Terrified of having inherited his mother's schizophrenia, he vehemently denies this and storms out of the office. Prior to this episode, Reid exhibited multiple signs of being in pain, such as gripping and rubbing his leg, rocking in his chair, cringing in pain while in the background, and putting a hand over his stomach as if he felt ill, and sensitivity to light.
He appears to be well in the following episodes, though in "Coda", he is seen carrying a book about migraines. In "With Friends Like These...", Reid confides in Morgan about his problems, remarking that he only read five books the previous week. Previously in "Valhalla", Reid had told Prentiss about his headaches. By then, Reid had gone to several doctors but no one has been able to diagnose what is wrong with him. He tells Prentiss that he has not told any of the team members because he is afraid that they will make him "feel like a baby".
In "Lauren", it is Reid and Garcia who react strongest to the news of Prentiss's death; when he's told, he tries to run out of the room and winds up sobbing on JJ's shoulder after telling her that he "never got a chance to say goodbye".
When Hotch and JJ told the team they'd faked Prentiss's death, Reid became very upset with JJ. He told her he felt betrayed because he "came to her house for ten weeks, crying" and she didn't say anything. He also mentions that he considered taking Dilaudid again after Prentiss "died". Reid also angrily referred to JJ as Jennifer, something he had never done before. He later made amends with both Prentiss and JJ.
In "Painless", Morgan plays a practical joke on Reid by giving his phone number to the press after Reid hustled him at a basketball game. The nonstop calls irritated Reid to the point he yelled into his phone, but from Morgan's reactions to the calls, Reid realized what he'd done and declared revenge. On the plane, Morgan's music is interrupted by a recording from Reid, which warned him against entering a prank war with MIT graduates, followed by Reid screaming. Reid smiles as Morgan's phone rings, apparently a call from Garcia. Morgan answers but is greeted with a response of more of Reid's screaming. Morgan then declared "it's on".
In "Epilogue", Spencer reveals that he had an experience with seeing the afterlife when he died and revived by Tobias Hankle, one where he felt warmth and the light. He then follows it up with that he's a man of science and that he didn't know how to deal with it, which is why he never revealed it to his teammates. That there was no quantifiable evidence that God exists and yet in that moment he was faced with something that he can't explain.
For the second time since the start of the series, he celebrates his birthday during an episode, this time his 30th during "True Genius", with the team. He relates to Prentiss that he feels that he hasn't lived up to expectations.
In "God Complex", Reid makes a series of phone calls via payphone to a mysterious woman. It is revealed that she viewed the MRI scans of his brain and has suggested a course of treatment for his headaches. He also appears to suffer from sleep deprivation. It is later suggested that perhaps the woman is possibly a geneticist. Reid behaves rather strangely when he needs to speak to the woman during the case, causing Blake to come back and confront him after she dropped him off at a payphone. Reid does not want the rest of the team to know about his mystery woman. It also appears that the woman is in some sort of danger and she fears that an unidentified male does not know about her relationship with Reid and she fears that "he" will hurt Reid. Morgan worries that Reid is suffering from migraines, but Reid has not been having them for awhile. He and his mystery woman have been in contact for six months and only on Sundays up until this point. Reid wants to have more frequent conversations and possibly meet her, but the mystery woman is afraid for his safety. She does say "love you" before hanging up, leaving Reid in awe.
In "The Good Earth", JJ lets the team know that her son Henry is afraid of trick or treating, saying that his friend told him that it's the one night of the year that real monsters can blend in with the children disguised as monsters. Later in the episode, he summons the courage to go trick or treating by stating that he will try to find out which monsters are the real ones and dressed up as his favorite profiler, Reid.
In "The Apprenticeship", Morgan takes Reid out to practice hitting baseball as his team is in need of another substitute player. After the case is finished up, Reid goes to watch Morgan's game and is drafted to play second base. At the bottom of the ninth, with the FBI team trailing by 1 point and Spencer up to bat, Morgan gives him a little pep talk and tells him to get out of his head and just play by feel as well as a chance to erase all his bad childhood athletic sports memories. With 2 strikes, Reid hits and makes a double play with Morgan, winning the game for the FBI.
In "The Lesson", Reid takes time to call the mysterious woman he admires several times throughout the case to get some insight. Towards the end of the episode, she tells Spencer that she's ready to meet in person and that she thinks it's safe enough. Reid and the mysterious woman both show signs of nervousness and anxiousness, mirroring each other simultaneously at their respective homes. Spencer shows up slightly before her with a book "The Narrative of John Smith" wrapped as a present. Spencer sees a man look over a few times and has a hunch that this man might be the stalker that his friend is so afraid of. He calls her to not come in and leave right away and goes to confront him, only to find out that it's the wrong person. He returns to his table disappointed and finds that his friend left him the same exact book as a present.
In "Zugzwang", Reid receives a collect call from "Adam Worth" at a payphone, only to hear the term Zugzwang, which is a chess term that describes the point in a game when a player realizes he'll inevitably be checkmated, and thus he has the decision whether or not to resign or play the game through to the end. This, coupled with the fact that they both use pseudonyms to disguise their letters, Spencer addressing himself as Dr. Joseph Bell and that the caller addressed himself as Adam Worth, whom was the American criminal that Arthur Conan Doyle based the character of Moriarty on, prompted Reid to seek the help of Hotchner, and through him the BAU. Visibly distressed, Reid pleads his case to his teammates, though Hotch reminds them that they're likely not to receive the case through the BAU, meaning that they'd strictly be using their private off time to work the case, everyone stays to help. The mysterious woman, identified as Maeve Donovan, is abducted by her stalker, also identified as Diane Turner, and despite his efforts to rescue her, he watches in horror as Diane simultaneously kills herself and Maeve with a single .45-caliber bullet at the end of the episode. He breaks down into sobs of grief.
Maeve's death left a lasting impact on Reid for the rest of the season. In "Magnum Opus", he is allowed to stay behind while the team investigates a case in San Francisco. During that time, Reid barely left his apartment and therefore never saw any of the gifts the rest of the team left behind by his door as condolences. However, Reid finally decides to catch up with the rest of the team but stays behind when the team identifies the unsub and discerns that the delusion that is fueling his killings will motivate him to commit suicide or suicide by cop. Indeed, the unsub is shot and killed by Hotch when he tries to kill another victim. In "The Gathering", Reid tries to reason with a man conflicted by murderous urges who was subsequently bent on suicide, but he is unsuccessful and the man slashes his own throat with a knife. This visibly upsets Reid afterward.
In "Alchemy", Reid, still haunted by Maeve's death, tries to remedy this failure by personally tracking down any potential cases and finds one in Rapid City, South Dakota. Throughout the entire case, he is consoled by Rossi and opens up to him about the fact that he never saw her personally prior to her death and that he never even touched her once. Reid also cites that he has barely slept, fearing that he will dream about her. When the case is concluded, Rossi successfully gets Reid to finally move on. Reid falls asleep on the jet and dreams about Maeve, whom he shares a dance with.
In "Persuasion", when a case came up in his hometown of Las Vegas, Reid calls his mother's sanitarium, intending to visit her. He is surprised to learn that her mental condition was beginning to improve, as she wasn't signed into the sanitarium as frequently and was actually allowed to have a supervised vacation to the Grand Canyon simultaneous to the investigation. When asked about it, Reid stated that he was overjoyed to learn about this, although he also expresses his belief that his mother might have actually forgotten about him, since they barely kept in touch. By the end of the episode, Reid receives a number of postcards and a golden collectible miniature of the Grand Canyon from Diana. These gifts please him, as that meant his mother still thought about him.
In "Angels", Reid was shot in the neck by a suspect while trying to protect Blake. He appeared to be critically wounded. In "Demons", the follow-up to "Angels", it was revealed that the bullet barely missed his carotid artery and he underwent surgery. He spent most of the episode in the hospital, where Greg Baylor, who was posing as a nurse, attempted to kill him by injecting carbenicillin into his IV. When Baylor, whose true identity had not been exposed yet, ignored his objections, Reid slapped the syringe out of his hand. Baylor then pulled out a gun, but Garcia shot him with Reid's own gun, wounding him. Reid was then escorted home by Blake, who opened up to him about her deceased son Ethan before leaving. Reid said goodbye and then found that she had left him her badge and ID.
Reid was the team member who was the most upset when Gideon was murdered by Donnie Mallick in "Nelson's Sparrow", even storming out of the crime scene in tears after Gideon's identity was confirmed to him. In the following episode "Hero Worship", Reid struggled to cope with the loss of Gideon. He began playing the chess game that Gideon had been playing prior to his murder in the hopes of keeping it going and thus keep part of him alive. Rossi later joined in the game to help him finish it.
In "Target Rich", Reid mentions to JJ that his mother wasn't doing so well with her current medications. As a result, he takes a sabbatical for a few following episodes so he can visit her. In "Entropy", Reid returned to assist the team in taking down a hitman network tracking down Garcia. During an undercover operation to capture its last two members, he indirectly reveals to the team that his mother was recently suffering from dementia, which he later confirmed directly afterwards. He also expressed his fears that he will contract dementia as well, since he missed the genetic marker of schizophrenia when he turned 30.
In "A Beautiful Disaster", it is revealed that Morgan partially named his newborn son after Reid. Morgan then assigns Reid to be the godfather of his son.
In "Keeper", Reid reveals to Rossi that his mother was accepted as a participant in a groundbreaking study on Alzheimer's, titled Metabolic Enhancement for Neurodegeneration, at Johns Hopkins University in Baltimore, Maryland. Reid is excited by the news, as earlier tests had found ways to not only slow the disease but actually reverse it. Later, during a case, he learned that his mother was found wandering around a casino, confused and not knowing who she was. She was safely taken in by police and has since recovered, but was embarrassed by the situation. By the end of the episode, it was revealed that his mother was one of the several participants who had to be cut out of the study due to unexpected budget restraints. This disappoints Reid, and he tries to find another study that his mother could participate in.
He eventually finds one in Houston, Texas, before the events of "Surface Tension", but later decides to take his mother out of it and bring her home with him so he could take care of her. After several unsuccessful attempts, he hires a caretaker named Cassie Campbell to assist him. However, Reid is forced to deal with the combination of his mother's schizophrenic episodes and lapses in memory.
At some point, in Houston, Reid met a woman calling herself Rosa Medina, a doctor who wrote an article on Alzheimer's. Between November 2016 and January 2017, Reid traveled to and from Mexico three separate times, all without notifying the FBI about his movements. In "A Good Husband", following the conclusion of a case, he informs Prentiss that he has some unfinished business to do in Houston. However, in "Spencer", he was arrested in Mexico on suspicion of drug possession with the intent to distribute, and the murder of Rosa, who was actually named Nadie Ramos, and who was found in a hotel room Reid was also at. He was nearly transferred to a maximum-security Mexican prison for Nadie's murder, but it was stopped when it was revealed that Nadie has dual American-Mexican citizenship, and he was extradited back to the U.S. However, the federal government refused to provide legal assistance for Reid, because he was never in Mexico for official government business.
In "Collision Course", Prentiss hired a lawyer, Fiona Duncan, for him. The prosecutor, A.U.S.A. Manny Martinez, offers a deal in which Reid pleads guilty to involuntary manslaughter in exchange for a sentence of two to five years in prison. After Reid turns down the offer, the knife used to kill Nadie is found in the Mexican desert, leading to another plea bargain of five to ten years in prison. Reid turns down this offer too, and later, he is denied bail by Judge Willa Frost, despite Fiona's best efforts.
In "Alpha Male", Reid is sent to Millburn Correctional Facility instead of protective custody due to overcrowding. There, he meets Officer Lionel Wilkins and inmates Luis Delgado, Milos, and Milos' gang Hicks, Dwayne, and Little T. He is nearly killed by Milos and his gang for taking back his belongings (which they had earlier stolen), but is saved by another inmate named Calvin Shaw, a former FBI agent imprisoned for killing his confidential informant. As a result, Reid befriends Shaw, who is also proficient in reading and chess, and who gives him tips to survive in prison.
In "Assistance Is Futile", Reid befriends Luis, going as far as reporting his assault by inmates Frazier and Duerson to Officer Peters. However, Frazier and Duerson brutally beat him in retaliation. Later, in "In the Dark", Frazier and Duerson attempt to recruit Reid and Delgado into helping them smuggle drugs into the prison. When Reid refuses, Frazier and Duerson later attack him and Luis in the prison laundry room, with Frazier slashing Luis's throat with a shiv and killing him. As a result, in "Hell's Kitchen", he agrees to help them. Meanwhile, Reid realizes Shaw has an extraordinary amount of influence within the prison general population, as Shaw had arranged for him to have another acquaintance in the form of Malcolm. Eventually, in an act of desperation, Reid poisons the drugs he receives, hoping to kill Frazier and Duerson. However, the two distribute the drugs throughout the prison, leading to five poisonings (including that of Shaw) that horrifies Reid.
In "True North", the prison is put on lockdown because of Reid's actions. This gives Lewis an opportunity to visit Reid and act as his personal psychiatrist since she has a Ph.D. Lewis gives Reid a cognitive interview; it is during that interview when Reid reveals he stabbed Nadie to death. However, she later tells Prentiss that she believes he manufactured the memory in a desperate attempt to find an answer to his circumstances. She resumes the interview on the next day, and Reid seems to remember the murder a little more clearly, recalling someone spraying a fine mist in his face during the attack in the hotel. This matched the M.O. of Peter Lewis, a serial killer by proxy who had been taunting the BAU since his escape from prison, and who was the BAU's prime suspect in Nadie's murder. However, when Lewis presses further, Reid remembers that the person who was with him and Nadie in the hotel was not Peter, but a woman.
In "Unforgettable", Fiona informs Reid that his trial was postponed, causing him to worry about his chances of survival in prison. Later on, Diana unexpectedly visits him, and they spend the remainder of the episode discussing it. During the conversation, Diana reveals that she threw Cassie out and hired a new nurse. At the end of the episode, the nurse comes to retrieve Diana. Upon spotting her, Reid remembers the woman as Lindsey Vaughn, whom he met a decade ago when he tried to stop her father from killing another person but failed, but the nurse denies being Lindsey before leaving with Diana. However, her words trigger another memory in Reid: she was the woman inside the motel room who drugged him and got him to kill Nadie Ramos. As he realizes this, the nurse looks back at him tauntingly, confirming her true identity. Reid tries to alert a guard and yell at his mother but is unable to stop the two from leaving.
In "Green Light", Reid alerts the team and has them check his apartment, but they find her missing and Cassie dead, nearly pushing him over the edge. Later, Shaw and the other inmates Reid accidentally poisoned are released from the infirmary. Shaw, knowing it was Reid who caused the poisonings, targets him by revealing his status as a federal agent to the other inmates. Shaw later tauntingly tells Reid that he won't see another attack coming, but Reid isolates himself in solitary confinement by stabbing himself in the thigh and pinning it on Shaw. Reid later gets released from prison after the BAU manages to prove his innocence. The BAU later realizes that Reid was framed by Lindsey and Cat Adams, a hitwoman who Reid directly captured in "Entropy". At the end of the episode, Reid and JJ go to the prison where Cat is incarcerated, with Reid preparing to face her again. The episode ends with Reid entering the interrogation room to confront her and Cat calling him "Spencie".
In "To A Better Place", Reid is officially reinstated as an agent under the condition that for every 100 days he spends on the job, he takes thirty days off. Prentiss arranges for him to teach seminars to new agents during his time off. Reid is shown to be considerably more aggressive on the job to the point where he obliterates a target during a training exercise and is more willing to use lethal force against an unsub. In "Dust and Bones", he mentions he is scheduled to give his first lecture after the team concludes a case. JJ mentions in the next episode that Reid was feeling apprehensive about his first lesson just before the team receives word of a new case in Miami.
On the Job
Reid joined the BAU at age 22 (stated in an article on his father's computer in "Memoriam"). One of his first cases was that of The Blue Ridge Strangler (Tabula Rasa). Though he went to the FBI academy, he had trouble with just about everything that wasn't book-related, including marksmanship, physical training, and obstacle courses. In the end, they had to make special exceptions to get him into the field (What Happens at Home).
- His sidearm was a Glock 17. Since The Angel Maker, however, he carries a Smith & Wesson Model 65 revolver with a three-inch barrel and wood-colored grips. He keeps his sidearm in an unusual appendix-carry, which was noted by a militia member, who said that the way Reid was carrying the gun, he was "just begging someone to take it off him" (Identity).
- However, in Penelope, he is briefly seen with his Glock holstered in the standard hip style, rather than his usual frontal appendix holster, despite being seen using the latter style holster earlier in the episode.
- In Masterpiece, it is revealed that he holds PhDs in Mathematics, Chemistry, and Engineering and BAs in Psychology and Sociology. He was working on receiving a BA in Philosophy and may have gotten it by now. In Big Sea, he also displays expert knowledge of forensic anthropology, being able to determine the sex and race of the skeletal remains. He showed knowledge of skeletal remains as early as Season One when he was able to identify the gender of a body based on the pelvic structure in "The Popular Kids".
- He considered studying the classics (literature) but had previously read all of the course material so he opted to go to Caltech and study Mathematics instead (according to an article on William Reid's computer in "Memoriam"). In Painless, he also mentions graduating from MIT.
- Reid has an IQ of 187, an eidetic memory, and can read 20,000 words per minute. (Extreme Aggressor)
- He is an expert on historical serial killers, statistics, geographic profiling, graphology, and body language.
- Despite not being able to pronounce Spanish words in Machismo and showing no knowledge of the Russian language in Honor Among Thieves, it seems he is able to read in some foreign languages (although they were never specified). Over the years, he improved his Russian comprehensive skills and understands it well enough to watch a five-hour movie in the language and speak it fluently. (Sense Memory, Fate, Rock Creek Park) He is also capable of reading in Russian now. (Fatal)
- Like many "brainiac" types, Reid tends to ramble on when the conversation leads to a subject with which he is very familiar. This tendency is somewhat annoying to his peers and they often verbally shush him or respond to him with blank stares.
- He is the only main character to appear in the opening sequence of every episode.
- He went to public school in Las Vegas and was frequently bullied. In one incident, he was ambushed by the entire football team; they stripped him naked, tied him to a goalpost, and tormented him in front of half the school until they grew bored and left. He never spoke of it until he told Morgan in Elephant's Memory.
