Trivia / Stargate SG-1 S4 E10: Beneath the Surface

• What Could Have Been: According to Joe Mallozzi, the Ship Tease in this episode wasn't a tease in the original drafts. Sam and Jack's alternate personas were explicitly in a relationship. A key component of the episode would be about them having to go back to their old lives, but having to give up their relationship. A legacy component of this subplot is present in the final scene of the episode where at the very end Jack and Sam remember their old lives and after Carter calls him "sir," O'Neill repeats the word sadly.
