Scully dates an autopsy Monday 11/14/94 (contradictory to 2x09: Firewalker, even if they had let her out of quarantine early). Given her state of mind during this episode, a mistake on her part is not impossible. Dates are based on the assumption she was off by one week.

12/22/94 – 12/24/94


Picket Fences 3x10 Away in the Manger


This episode of Picket Fences was written and intended to be a crossover with the X-Files, picking up where the events of 2x10: Red Museum left off.  Although CBS nixed the idea at the last minute, direct references to "Red Museum" remain in the episode.

Takes place on Christmas.  Specific mention is made of the FBI being "all over Delta Glen for the last week."
