Damn it,
Keila, come home.
Edit: YAY, YAY, YAY! She could NOT, in fact, remember how to get home. She did remember where she'd last seen me & Nick though, and whenever she eventually got tired, she had gone back there. We found her curled up on the ground between the cars in my former boss's driveway, since we'd borrowed flashlights from Devra and gone to return them upon giving up the chase.
