Buffy’s most significant experience?

I think becoming a slayer was probably the most significant. Although, the other choices are very significant as well.

Willow’s most romantic moment?

Tara, skipping the long important process was one of the most romantic moments in the whole series. Period. Such a beautiful scene.

Xander’s favourite holiday event?

Xander in a bra. Nuff said.

Angel’s most satisfying piece of revenge?

Riley was being cocky and needed his ass kicked.

Spike’s favourite fake relationship with Buffy?

The Buffybot cracked me up. You just know JM and SMG laughed their asses off doing those scenes.

Giles’ favourite job?

Being a Watcher, of course. Even after he was fired, he kept doing it for free.

Buffy’s best boyfriend?

Actually, I wouldn't have picked any of those choices. But I'll go with RJ.
