10 Buffy The Vampire Slayer And Angel Plots That Were Never Resolved
5. Oz
Daniel Osborne was one of the core Scoobies in the third and fourth seasons of Buffy The Vampire Slayer. He was introduced back in the second season, before being quickly revealed as a werewolf. His stoic demeanor suited the story perfectly as his human and wolf sides were diametrically opposed to each other.
His affliction was accepted by the gang and he and Willow began seeing each other, with monthly chain up sessions to look forward to. Going into the fourth season, the writers decided to address how life was changing the way they were with each other, in keeping with the theme of college changing the teenagers.
Oz grows close to a fellow werewolf, Veruca. He cheats on Willow with her, leaving Sunnydale a broken man. He returns later, having learned to control the wolf side, only to find that Willow has moved on with Tara.
Though the door is left open to a further return and there were plans to introduce him to the never-produced sixth season of Angel, that is the last time the audience sees Oz. There was plenty of room for this story to continue growing, as he was the one person that had mastered being able to control the change at the Full Moon.
