I've always wondered what would happen if Buffy had left the Magic Box before Willow's spell took effect.
So here's the challenge:

Buffy walks out before the spell goes into effect, so she doesn't lose her memory with the others. When Dawn, Willow and Tara never come home, she goes looking for them and finds everyone at the Magic Box. Being the only one with any memories of magic, demons, vampires, etc, she manages to pull everyone together into a working team. Once the spell is broken, what happens?
