Her arch nemesis
Buffy never spared her a second glance after a fight. Never. Even though Dawn locked herself into her room, she knew that her sister's first target was the fridge. Always the fridge. That damned thing was more of a relative to the Slayer than she ever was. So Dawn got an idea, find a way to lock the fridge.
And here Andrew came in handy. Well, needless to say that when Buffy stormed in with the dog chain and the lock into her room, Dawn pushed him forward. So yeah, there she stood in her bed, scanning the walls with her eyes in search of something fun to do that didn't imply the phone, the computer or going out.
That damned fridge.
