- This episode was originally set to air before "The Big Game". However, due to a shift in airing schedule, several changes were made: Three scenes were re-shot (including a scene on the jet between Morgan talking about Prentiss with Reid), a scene that reveals Reid's addiction to Dilaudid was inserted, and flashbacks of the events that occurred in "Revelations" were added in order to maintain continuity.
- Groton is a real town in New York, but it is actually located in Tompkins County, which is 219 miles northwest of Westchester County, which was said to be Groton's location in the episode.
