Manning confronts the father and he says that he let his son make the decision. She says that he is mentally incapable of doing that because he is so young.

Halstead talks to Maggie about lying to Nina and admitting his feelings for Natalie. She tells him women don’t usually like to hear about their boyfriend’s feelings for other women.

Charles explains to the husband that they are going to meet Becca now. Grace says that it will take a minute and then she starts talking with a different voice. She fights with the husband. She says that she has been around since high school and has helped Grace for years. Charles doesn’t want to just put a label on her and move on but Reese can’t handle that. She quits.
