Willow moves in with modern Laura and Kathrin, suggested by Scrubb!
For those confused, Willow's body will go around on autopilot when separated from the lamp. And apparently something's blocking willow's lamp top from opening. Probably the rest of the stuff Willow packed in there.
Her body's not really this independent in her original story, it's normally only able to do basic tasks, but maybe in the modern setting she's evolved a little.
