10 TV Episodes That Everybody Pretends Never Happened

3) Angel, "Eternity"

In this episode, Angel is drugged with a "euphoric" and briefly turns into Angelus… because apparently drugs are as good as true happiness (yay shortcuts!) A lot of people hated the episode (if you can just turn Angel evil with a pill, why don't his enemies do that all the time?) but Tim Minear has defended it:

I know there was a lot of criticism on the Internet about the way he went bad, and did he really go bad? The idea of giving Angel a variation of ecstasy—

to me, that just worked. I thought it was a really good way to bring Angelus into the series for a moment so that he could interact with our characters for a moment, without doing some big 'Angel has turned evil' arc. You sort of get to have your cake and eat it too in that episode. It really works when he goes evil.

At the same time, Angel never took an "evil" pill again.

5) Buffy the Vampire Slayer, "Normal Again"

In this episode, Buffy is attacked by a demon whose venom causes her to believe that she's actually in a mental hospital and that the last six years have all been a hallucination… or, possibly, we discover that Buffy is in a mental hospital and that the entire show has taken place in her mind. The famous final scene, showing Buffy back in the mental hospital, leaves room for interpretations either way, and Joss Whedon has said that people can make up their own minds on the matter. For his part, though, he thinks that the events of the series really happened. The show never alluded to the "Buffy in a mental institution" scenario again, in any case.

Pour le premier je ne me rappelle même plus XD et le second est un de mes favoris, mais c'est clair qu'ils posent des questions et éventuelles réalités que nous les fans devont oublier si on veut que notre monde fictionel préféré existe :p
