|Portrayed By||Mark Povinelli|
|Appeared In||The Lesson|
Not much is known about him, as he is a puppet with no real background. What is known is that when Adam recovered from a coma induced by a serious car accident, Mr. Conrad became his only friend and convinced him to start his series of killings.
Throughout the episode, he is assumed to be an actual person aiding Adam, though his extremely short stature, the fact that Adam is the only one that talks to him and vice versa, and the victims only pay attention to Adam when both are in the room can be seen as giveaways. He participates in Adam's play The Robbery, in which he portrays the robber who killed Adam's father Alex. However, the BAU interrupt the play and reveal to the viewers that Mr. Conrad was a puppet the entire time.
