Grayson: Captain Mercer, meet Captain Dalak
Mercer: It's good to meet you, Captain. We owe you one.
Dalak: Try to stay out of our way.

Dr. Finn: Lots of people say that home is wherever you make it.
Isaac: A human cliche.
Dr. Finn: Cliches become cliched precisely because they're valid enough to bear endless repetition.

Isaac: I am using my optical scanners to construct a spectrographic image of Kaylon. The star is very distant but repeated efforts will eventually yield a result.
Dr. Finn: You're taking a picture of home.

Halsey: I want a safeguard. An off-switch of some kind to make sure we can control him.
Mercer: That's exactly what caused the genocide on his home planet. We can't keep him in servitude like his Kaylon builders did.

Keyali: [Isaac] saved us. We have to try to save him.
Malloy: Yeah, but the only reason he HAD to save us is because he screwed us in the first place.

Captain, it seems we have a common enemy. I hope that means we can work towards finding a common ground.

Mercer

All right, buddy. Time to wash your mouth out with Gordon.

Malloy

Mercer: Evasive maneuvers. Narrow targeting scanners. Concentrate your fire.
Bortus: Scanners cannot penetrate their hull.
Mercer: Do... eeny-meeny-miney-mo. Pick a spot!

Malloy: Just so you know, this could rip the shuttle in half.
Grayson: I don't want to know.

Malloy: Piloting a shuttle out of the bay while the ship's at quantum speed is incredibly dangerous.
Grayson: How dangerous?
Malloy: On Day 1 of pilot training, they tell you don't ever attempt it.

Mercer: I've been on board a Krill ship. You haven't
Grayson: I'll take Gordon. He was there with you.
Malloy: Oh, man. Pee corner's looking real good right now.

Malloy: Sorry, I was in the pee corner.
Grayson: The what?
Malloy: Oh, well, there's no place to go to the bathroom down here so we all agreed on one corner. Yeah, no, trust me, you don't want to go over there unless you have to.

The Orville Season 2 Episode 9 Quotes

Grayson: We're on our way to Earth with their... ambassadorial delegation.
Marcos: That's one big delegation.
Grayson: Well, they're...
Mercer: They're very big on ... pageantry.

Dr. Finn: How the hell can you even look us in the eye after what you've done? We all trusted you. My kids still do. They honestly believe that you'll protect them.
Isaac: I understand. It is a common weakness of biological life forms.
