2x20 (ep 42) "What Is and What Should Never Be", directed by Eric Kripke, written by Raelle Tucker (May 3, 2007)
- In the theme of "what could have been and maybe my alternate life means I'm crazy", along with Buffy the Vampire Slayer episode "Normal Again", The X-Files episode "The Sixth Extinction II: Amor Fati", and The Last Temptation of Christ. Compare and contrast with the djinn episode of The X-Files ("Je Souhaite"), in which Mulder, rather than being given an alternate life, gets to make wishes.
