Recap / The X-Files S06 E12 "One Son"
Mulder learns the truth about the Syndicate that's collaborating with the alien colonists, just in time for the Syndicate to be wiped out by the alien rebels.

- Continuity Nod: Fort Marlene and it housing an alien fetus were previously established way back in "The Erlenmeyer Flask".
- Cryptically Unhelpful Answer: Mulder's "explanation" of events at the end. Not even Scully adds any facts to the conversation.
Mulder: They burned themselves. With a choice made long ago by a conspiracy of men who thought they could sleep with the enemy. Only to awaken another enemy.
Kersh: What the hell does that mean?
Mulder: It means the future is here, and all bets are off.
Kersh: Agent Scully, make some sense.
Scully: Sir, I wouldn't bet against him.
- Deadpan Snarker: Mulder has a couple.

There must be some kind of mistake. I signed up for the aroma therapy treatment. Mulder
: (as Scully scoffs at a plain outfit after their clothes are burnt) I heard gray is the new black.
