Bennett and Mouse are driving to Seattle. Bennett is wounded still.

Mouse is having a flashback. She was a nun in training and Marcus was trying to convince her to leave the nunnery before her initiation. He tells her that he's different because he didn't choose this life. It chose him. 

Marcus tells Tomas about Mouse.

Peter gives Marcus a ride home. He tells Marcus after he's done with Andy they need to get together and he should retire. Marcus thanks him and kisses him then goes back into the house.

Verity arrives with Rose and she goes to talk to Andy. The demon throws out some serious daggers, but Verity remains strong. Andy has the shard and fights the demon from hurting Verity. Prime opportunity for Marcus and Tomas to fight the demon. Verity leaves. She got done what they needed to get done.

Mouse has another flashback. Another priest had to complete her exorcism because Marcus couldn't get the job done. His first failure.
