Buffy The Vampire Slayer: Every Season 2 Episode Ranked
9. Phases
The central mystery of Phases is about the identity of the werewolf terrorising town. Whilst Buffy confronts Angelus's evil side once more, Oz learns he's the werewolf his new friends are hunting, just as he and Willow really fall for each other.
Phases is at once a sweet shot of teenage romance and an intriguing mystery that gives newcomer Oz heaps of much-needed and well written development, all of which comes complete with some surprisingly effective practical effects.
From here, Oz would become an integral part of the series, and Buffy's feelings about killing Angelus start to change and push the season's drama forward in a subtle and affecting way.
