Recap / The X-Files S07 E02 "The Sixth Extinction II: Amor Fati"
Adventures in Comaland: While in a coma, Mulder dreams he is led by CSM to a simpler life, where lives in a suburban neighborhood, is married, has children, and his sister is alive with children of her own. He leaves behind his quest, and the sequence ends with CSM comforting Mulder in his deathbed, curtains hiding the alien invasion happening outside.
Dream Within a Dream: Mulder has one of himself and a young boy on the beach building a spaceship while living out his alternate life in his coma.
Shattering the Illusion: Scully (as herself, not aged as Mulder is at the time) appears in Mulder's coma at his deathbed and berates him for giving up.
