Rosa: Jake, this guy saw the perp. We have to get him in front of a sketch artist.
Jake: Oh, yeah. I'm feeling it now, Rosa. At this time tomorrow, we're gonna know exactly what our killer looks like.
[later:]
Rosa: We have no idea what our killer looks like.
Jake: Well, that's not totally true. We now know that the killer might look like Seth Myers, Winona Ryder, or Bilbo Baggins.
Rosa: The delivery guy kept starting over. Apparently, he's always high.

Rosa: I want to say a few words. When Jason died seven days ago, I didn't give a rat's ass.
Charles: This is your speech?
Rosa: 'Cause I didn't understand why people care so much about their dumb dogs till I got a dumb dog myself. I've only had Arlo for a day and a half, but if anything happened to him, I would kill everyone in this room and then myself.
Gina: Very violent eulogy, I like it.

Rosa: Hey, you should run. Going to meetings, writing stuff down. You love that nerd stuff.
Amy: Writing stuff down is nerdy? What do you do?
Rosa: I just forget stuff like a cool person.

Sergeant Jeffords: Wait, is that a smile I see?
Rosa: Possibly. My immune system is too weak to fight off my smile muscles.

Jake: So, we gonna talk about what happened back there? I haven't seen someone cry that much since Charles heard they were remaking "First Wives Club."

Jake: Whoo! I love the first walkthrough of a crime scene. It's kind of like arriving at summer camp, except the lake is full of blood and your bunk mate is dead. I think I might be bad at metaphors.

Captain Holt: I'm here because Major Crimes wants this case. I was hoping to tell them you have some leads. I overheard you mention a Bill Bo-Baggins. Should we bring him in?
Jake: Well, as much as I would love to meet him, he is not a suspect.
