- "We'll Get By" by Gary Louris
- David Rossi: "Within the core of each of us is the child we once were. This child constitutes the foundation of what we have become, who we are, and what we will be." – Neuroscientist Dr. R. Joseph
- Aaron Hotchner: "There is no formula for success, except perhaps an unconditional acceptance of life and what it brings." – Arthur Rubinstein
- This is the first of nine episodes that dealt with two separate cases. The second episode is "The Crossing", another episode in the same season, and the rest is part of an arc involving Reid in Season Twelve.
- In the episode "Birthright", Rossi informs John Caulfield that it has been twenty-one years since the double homicide in Indianapolis occurred. However, in this episode, it is then stated by him and others to be the twentieth anniversary of the crime.
- In one scene, there is a "Legacy" sign on a carnival area fence, which is obscured to read as "Gacy", a reference to real-life serial killer John Wayne Gacy.
