The girl from earlier gets home, and her dad gives her a hard time. He doesn't seem like such a bad guy until later when he goes into her room and gets in bed with her. Seriously WTF. Is this her father?

Ressler and Samar meet with Jawal's wife which is the daughter. So it's guys who marry young women. Sick! The girl is only 16.

Samar really digs in the questioning and the girl gets weirded out. Aram finds some information on her computer -- a child bride support group. And then a guardian angel who is also known as Anna.

Harold wants them to find out more about this guardian angel, but Samar thinks they should drop it. She doesn't think that it's a bad thing that someone is killing men who are marrying children.

Turns out Jawal's wife is pregnant.

Anna has nowhere to go. Anna tells Samar her story. She was raped and reported it and then forced her to marry the man.

Samar tells her own story about her parents died when she was 9. She had a cousin who married when she was young. This is why she has a vested interest. Samar promises her she'll help her.

Liz and Aram are at an airport talking to a guy who says he saw Tony. It turns out to be a set up by Garvey who wants Liz but Red and his men show up and save her.
