There is a blurry flashback/dream sequence of someone being knocked down some steps during a search.

Regina comes to the prisoner loading dock and so does the ADA, who says Regina can't be here.. They exchange words and Regina wants her father to serve time closer to New York.

Morales is supposed to talk to her son's class for Career Day. The teacher pulls her aside and says policing is a polarizing subject and that the parents are uncomfortable with seeing a cop in their school. She rambles on about how they need to be inclusive so therefore police aren't allowed. Morales is offended.

The cops arrive at the home of the woman from the first scene. It's apparently a home invasion robbery. A guy standing by the barrier offers advice. Another guy hanging around runs when Bentley asks him what's up. The cops chase and catch him.

Morales comes in and Suarez asks her que pasa. She says that she realizes now that having a cop as a mother is tough on a kid.

Regina goes to see her father, who talks about a trophy he has. She tells him she's worried. He thinks Kurt Walsh has no credibility. She thinks the ADA will be going after cops to make a name for herself. He has a lawyer. Regina doesn't approve of his lawyer. Her father doesn't want to talk about this. Does she think he has anything to do with the killing of the CI? It matters to him if she does. Regina doesn't. That's enough for him.

Morales and Kilian go hard on the suspect, who is the victim's son and has a ton of pills on him that he says are for personal use. Morales is in a bad mood still about what happened at her son's school. Justin claims not to know anything and wants to see his mother.

The ADA comes to see Suarez. She complains about Regina coming to see her. She says Regina is being inappropriate and wlil order an official inquiry if she doesn't back off.

Regina goes to see her father's lawyer. He promises he will ask for help if he needs it. He also tells her he has Walsh's affidavit. Her father was the UC who was there during the shooting. A prostitute on the scene has not been identified.

Morales has no patience for small talk with Killian. She's annoyed that he can't get a security video to play. He asks her what's wrong. She tells him what happened at the school. Tommy thinks she should change schools for Sebastian. She doesn't think so. She's upset that he was so excited to have her in his class. Anyway the security footage shows the perp wearing a police uniform.

Suarez talks to Regina and tries to convince her she needs to stand down. He says that Yolo's murder going unsolved weighs on him. He says she can't interfere in this investigation.

Regina's father comes by just as she learns about the cop who is involved in the home invasion robbery. In private she wants to know baout him being a UC. He says the context is that there were cops who were gangbangers and he had to put a stop to it. He says he didn't feel bad most of the time but some cops he regrets. Regina asks about Kurt Walsh. Her father says he reported him all the time. He was always beating perps up, including a 100-pound kid. Walsh did all sorts of things and never got busted until recently.

Sanderford has a tiny shield he's going to give to Tamika. Bentley says things must be good between them then. Sandeford is very happy. Bentley gets a text about the cop behind the assault. He looks familiar.

Morales says something feels wrong. Bentley and Sandeford come along and all realize he's the know it all who was standing outside, not a real cop.

A woman comes uup to the fake cop and claims to be lost. He offers to walk her to her destination.

Sean asks Regina if she's coming to bed. She has too much stuff to go through. She doesn't know what she's looking for or why her dad held onto all this stuff. Regina finds a photo of her father with a girl on his lap and rushes off to conffront him. It happened on her birthday. He says he was working. He had to be around unsavory characters even when he should have been  with her. She asks did he sleep with this girll and tells him to stay away from her.

Regina asks Sandeford about the girls. He knew all of them. H eknwos their first/nicknames. He offers to find their real names but Regina turns him down.

The old lady comes in to tell Kee that the fake cop was so nice to her. She wrote down the badge number.

Sandeford tells Morales that the victim is awake. The fake cop pretended to be a parole officer. She's upset about the school incident still. Yenko comes in. He finds out the fake cop is a retired real cop and lives in Bay Ridge.

REgina finds one of the girls. She is working as a crossing guard. Regina tries to question her and she claims not to know what she is talking about. She finally asks how Mo is. She's the only one left as the other two women are dead. She calims not to know any Kurt Walsh. Regina gives her a card so she can stop any witness intimidation. She tells her to tell the truth. Angela tells her that her father always paid her bail when she was arrested and is a good guy.

George comes and recognizes the photo. He says Carl is a police buff and he gave him a duplicate shield. He's surprised to hear Carl could be in trouble. He was a nice guy who helps people across the street. He has a bunch of his stuff in his garage.

Carl has a scrapbook of signed photos of commissioners. He also has a photo of a stolen cello. He has rubber guns but real ammo.

The cops learn Carl was fired as a doorman because he went into an apartment when the people weren't home looking for a stolen cello.

Angela comes to see Regina. She wants her to come to the courthouse with her. SHe can't go in the grand jury room but she'll stay with her whle she's waiting.

The fake cop gets free coffee and sees on the news that his repalcement caught the thieves. He's angry that Larry was given the credit and runs off. He follows Larry and attacks him with a gun. He wants Larry to tell the news the truth. Brandy arrests him and he claims he knew she was a cop.

Carl claims he should be sitting where Morales is sitting. He didn't get to be a cop because he failed the psych exam. He says attacking the woman was an accident and was a misdemeanor. He starts arguing and stating laws. He insists he is a cop. He says it's a calling, something you're put on this Earth to do. He says it doesn't matter what others think of cops -- they need us.

Regina goes to the prisoner dock. The ADA tells her his father was cleared. Walsh comes out and says a lot of crap to Regina about her father as he is being led away.

Regina returns and Suarez tells her the truth comes out without her getting involved.

Sebastian tells Morales his friends don't believe his mom is a cop. Sandeford and Bentley give him and Morales a ride home in front of all the kids. The teacher looks mad.

Regina's father shows up at the precinct. He is grateful for what she did. She's glad it worked out. She thinks he should call Angela by her name. He says he made mistakes. Regina says this went beyond that. He didn't want to hurt her. She says b ut it did. She knew he left them. But she thought it was because of job stress. She never thought it was a woman who either put out or got sent to jail. He tells her it wasn't like that. She doesn't want to hear it. She's done with him.She kicks him out and sits in her office crying.
