Sergeant Jeffords: I hope they take that container of bugs with them when they go.
Rosa: Wait. The container's here? I have an idea. All I need is some blood.
Hitchcock: This is fresh.
Rosa: Oh. Terrible, yet perfect.

Amy: Hey, I think I found something interesting. I was double-checking last month's surveillance photos, and I noticed this. Hawkins has two different phones: her normal cell, and then this one that only has one app on the home screen Snapchat.
Hitchcock: Oh, she's up to something. Snapchat messages disappear. You can send anything to anybody, and after they see it, it's like I never sent it.
Captain Holt: Nobody ask Hitchcock why he knows that.

Sergeant Jeffords: Hitchcock called himself Scully by accident.
Hitchcock: I did, but it brought me and Scully closer together.

Amy: Hitchcock, why do you have your shirt off?
Hitchcock: Can't spill food on your shirt if you're not wearing one.

Gintars: It's gift for Nikolaj.
Charles: Nikolaj?
Jake: How do you know Charles's son?
Gintars: My name is Gintars. From Latvia. I am Nikolaj birth father.
Charles: Ohh! Nikolaj's birth father who I'd never hope to meet. Very cool. Cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, c-c-c-c-c [passes out]

Dr. Ronald Yee: The flies don't sense blood. They're just regular flies.
Amy: But, Dr. Yee, you can't be a fraud. You gave a TED Talk.

Amy: What are you saying out of your weird face?
Rosa: We put the flies near fresh blood, and nothing happened. They didn't react at all.
Captain Holt: Do you know how stupid these accusations sound? Diaz, you're fired.
Rosa: What?
Amy: Dr. Yee is one of the most respected forensic experts in the country.
Captain Holt: For you two - let's not mince words - common fools to suggest that you found the flaw in this brilliant man's-
Dr. Ronald Yee: They're right.
