Captain Holt: Peralta, you made an arrest in the bus bombing?
Jake: Yes, look, I know that I was told to back off, but something just didn't sit right, so I went back up there, and I caught the guy. He was snooping around. Now, he's not talking yet...
Captain Holt: Because he didn't do it.
Jake: What?
Captain Holt: The feds already solved the case. There were prints on the bomb, which led to a suspect who confessed immediately.
Jake: Well, why didn't anyone tell me that?
Captain Holt: 'Cause they didn't have to because it's not your case.
Jake: So I arrested an innocent person?
Captain Holt: Yes.
Jake: Oh... that's not okay. Uncool, uncool, uncool, uncool, uncool, uncool, uncool, uncool, uncool.
Captain Holt: Are you saying cool or uncool?
Jake: Uncool. It's just hard to say it fast, but this is bad!
