Petra: You’re going to get me killed, aren’t you?
Mariner: Only one way to find out!

I want to see Commander Data level work, people! Those isolinear chips better be a blur!

Billups

Buenamigo: Starfleet is so competitive. Once you’re an admiral, you hit a wall! I’ve been trying for years to make a name for myself. I’m not letting you take it from me. Not after everything I did to get us here!
Freeman: Everything you did? Wait, that means…
Buenamigo: Yes, yes, I set you up.

I know. Starfleet’s just an idea, but the people matter.

Mariner

Rutherford: Woah, these Texas-class ships are amazing!
Tendi: Rutherford, stop being impressed with the thing that’s stealing our jobs!

The longer Mariner’s not around, the more Boimler loses his grasp on reality.

Rutherford

Tendi: God, we would’ve won if I hadn’t defended the life of some inert dust.
Boimler: Ah, when secondary scans find life, you have to drop everything. That’s, like, the entire point of the Prime Directive.

Rutherford: He used my designs, my code. [gasps] That’s the same code I used for Badgey!
Tendi: Oh no! A starship can’t have daddy issues.

Freeman: You are not one of those bad-faith admirals that’s up to no good. You’re better than this, Les.
Buenamigo: I’m really not.

Mariner: I think, deep down, I was looking for a reason to go back to Starfleet.
Petra: Are you joking? You just escaped all that.
Mariner: I know. But I think I want to be a part of something that stands for the greater good.
Petra: Oh, and archeology doesn’t? That’s a bit f*cking rude.
Mariner: No. I mean, it’s fun, but how many old, brown pots do we really need?
Petra: All right, well, that’s just even ruder.

Starfleet was founded as a way for humanity to advance into the stars! This would undo centuries of progress.

Freeman

Freeman: No, get out of here! The Aledo is too powerful. A Cali-class ship won’t stand a chance!
Mariner: I know, right? That’s why I called all of them!

Star Trek: Lower Decks Quotes

Boimler: Romulan whiskey is against regulations!
Mariner: Yeah, because it's awesome.

First contact is a delicate, high-stakes operation of diplomacy. One must be ready for anything humanity is interacting with an alien race for the first time. But we don't do that. Our specialty is SECOND contact. Still pretty important. We get all the paperwork signed, make sure we're spelling the name of the planet right, get to know all the good places to eat...
