ST:TNG, Tapestry and Birthright, Episodes 615-617
(Episode spoilers)
Picard effectively "dies," and is shown (by Q) what could have been as a result of different decisions made when he was young. As a result of taking the "safer" route and avoiding getting stabbed through the heart (literally), he's shown a lackluster career in a lackluster life. He demands of Q to return him to his past life, where he dies a Starfleet Captain rather than a Lieutenant Junior Grade in the Astrophysics department. He even has an emasculating blue shirt rather than the captain-y red.
A goddamn horrible episode to watch after coming home from a frustrating day at work. Okay, Q... I've seen enough.
Birthright was interesting enough, even if it was the same old what-it-means-to-be-Klingon story. A decent two-parter, and had a fun sequence (that was ignored in the second half) where Data was dreaming. Oh, and Doctor Bashir for some reason was on the Enterprise? DS9 started airing three months prior, so I guess they were doing some sort of crossover.
