Undercover Eddie gets made by some woman who knows her. The guy leaves and Eddie tells her friend that she thinks the guy is a serial rapist. Her friend doesn't believe her. Sergeant Williams says Eddie is off the case.

Ray comes to see Frank. He asks if this is about his son. He quotes the relevant police code that he broke to Frank but says that there's nothing in there about fathers and sons. Frank doesn't buy that. Vincent is an adult and makes his own choices.  He says he's sorry for where they find themselves. He doesn't want to lose Ray but Vincent lives with him and has access to his weapon. Ray says that he locks up his weapon at home. Should he turn his back on his son because he's an addict?

Erin shows up at Joe's and accuses him of tipping Deanna off. He denies it and wants to help find her but Erin won't let him.

Baez and Danny question Ashley. She says she would never kill Mimi. She needed to know Bill was useless, but Bill denied everything in her tell all. Danny says they have grounds to arrest her for extortion unless she helps them. Ashley says Mimi wanted to file for divorce but didn't want Bill to get half so she was trying to prove he was trouble.

Frank brings up CIs to Sid. He says cops associate with them and they're criminals. He wonders how many times he can bend the rules before the costs outweigh the benefits. He thinks he is getting too soft.

Frank talks to Henry about the situation. Henry was the one who put that rule into place. His brother-in-law was a criminal and addict and Henry had to disown him. Henry pretended Albany demanded it and his wife seemed to believe him. He did what he had to to keep them safe.  He never regretted it. He made this rule when he became PC because it wasn't fair that his relative put his partner's life at risk.

Ashley has an alibi and so does Bill. Baez gets the autopsy and finds out that Mimi died of an allergic reaction. Everyone knows Mimi was allergic to nuts so maybe it was a murder.

Eddie admits she has changed her mind about becoming a sergeant. Henry offers to help her get a job at special victims. Jamie teases her about how if she was a sergeant she wouldn't enforce the hairstyle rules.

Anthony has some evidence. Erin says she can't look at it because Joe stole the files from Deanna's apartment. Joe says anyway she's missing and this guy's dangerous, they have to find her. Erin says fine but we do it my way, by the book.

Erin, Joe, and Anthony stake out an address. Adrian is there and Erin won't enter without a search warrant. Joe argues that Deanna might be in danger. Anthony agrees. Just then they see Deanna be put in a van. The cops shoot the kidnapper and rescue Deanna. She is shocked to realize Joe is a cop.

Bill can't believe Willis did this. Danny asks Bill what his plans are for the next chapter of his life now that Mimi is gone.

Frank says Vincent is old enough to live on his own and that Moretti has to kick him out or lose his job. Frank says he knows Moretti cares about Vincent, but they both know it isn't working with him living here.  He says he would know it was time if it was him because the house got shot up while he was living here. He says Morettti's son will call him a a hardass but that's a good thing because it means he's still around to say it.
