Back at the house, Mel thinks they are dealing with a shadow demon. Harry wants her to work on her thesis instead of research. He suggests that maybe she should freeze time to help her since it would be minimal personal gain, but another power outage is reported and they have to go.

The sisters come up with a plan. They wait for the demon to come.

Macy thinks there must be some evil in her, but her sisters tell her not to jump to conclusions.
Macy goes to Julia and tells her that she doesn’t want to fire Galvin because he’s an asset to the team. To solve the budget shortage, she wants to test things in house and find a way to make up for the remainder of the money. Instead of Galvin, she ends up firing the slacker of the lab.
Mel decides to drop out of school and she’s no longer sure what she wants from life.
