Day 19. Character you like that everyone else hates. Again, not sure I know who everyone else hates. People seem not to like Kennedy and Glory; I thought they were ok. Glory had some great lines and a really good plot device in the form of Ben.
Day 20. Best Spike-centric episode. They're all great, obviously. But I think I like Lovers' Walk largely because of this piece of dialogue from Spike: "You're not friends. You'll never be friends. You'll be in love 'til it kills you both. You'll fight, and you'll shag, and you'll hate each other 'til it makes you quiver, but you'll never be friends. Love isn't brains, children, it's blood. Blood screaming inside you to work its will. I may be love's bitch, but at least I'm man enough to admit it."
Day 21. Best Willow-centric episode. Doppelgangland. I love vampire Willow and this is close on one of my favourite episodes of the whole show. It's a little slice of a different imagining of Buffy, how it might have been if Whedon was a grittier, darker writer.
Day 22. Best Xander-centric episode. Xander doesn't have that many episodes to be centric in, does he? I think The Zeppo from Season 3 because Xander gets to take care of himself and learns that he can. The Triangle is fun too, but I'm not sure it's really Xander-centric.
Day 23. Two characters you wanted to get together that never did. Spike and Faith. That would have been hot. And also Joyce and Giles, even though they kind of did a bit in Bandcandy.
Day 24. Favourite example of 90's special effects. There's a training montage moment in When She Was Bad in Season 2, where it is clearly SMG's stunt double.
