Erin is used to strange things happening when she's roommates with a witch, but she doesn't always take Elizabeth's powers as seriously as she should. When a spell to summon a coffee shop to their building goes ridiculously wrong, Erin finds herself suddenly carrying around A LOT more mass -- Elizabeth's goof causes the timeline to alter so that Erin weighs 600 pounds! And it isn't just that she's huge now, she's always been huge! How is Erin going to adjust to a world where everyone remembers her as a heavyweight? And can Elizabeth fix things? And, when it comes down to it, do either of them want to fix things?
