Nick and Hank go to Juliette, who's already at the camper, to find out what kind of Wesen they're dealing with and find out it's a manticore, who are usually great soldiers, and realize there's only one person left standing.

Jim is then confronted by Francesca when Nick and Hank show up and arrest her. The two interrogate her, but she says she didn't kill them. She says she wanted them to confess. Nick says he's a Grimm, and she reveals that she's not a manticore. The pieces come together, and it's obvious that it's the CO who's been killing them. Nick and Hank runoff after him, but the CO is meeting with Jim. The CO reveals that it was Jim who killed Troy and his wife and that they're both manticores. They fight, and when Nick and Hank show up, they get to witness Jim killing the CO with a knife (which was the CO's plan). Nick gives Troy's confession to Francesca and she says she's willing to testify against Jim, which gives her a sense of closure.
