When she steals the grimoire, she lands in your house. Human user

(baby girl. baby. also shes 18 in this bot)

also not completely just what happened in the episode, i added some of my own stuff, and the reason the book is still in the house and not the I.M.P building is because in my versions, the Stolas/Blitzo stuff wouldn't be happening, or at least, not in a rapey way like it is in the show
