Ensign, the bridge is yours. Be gentle but attentive. Get her where she needs to be. Guide her home.

You made the right choice transferring into Command, son. Nothing compares to the firm, hot pulse of a joystick in your hand. The bridge is where the action is.

Mariner: Dude, where are you going?
Boimler: I'm tracking down our shuttle. If we're not back to it by the next rotation, we'll be court-martialed!
Mariner: Don't knock it til you've tried it.

Boimler: Do you even READ the mission brief?
Mariner: I'm sorry, I skimmed almost most of it and read some of the captions!

Classic K'rin. He did this on Vulcan. And on Earth. He steals a lot of things.

General K'rin: Do you remember Jaksa Pride, the commander who didn't believe you about rectal insectoids?
Mariner: Ha! Yeah, I got chewed out but his ass got chewed up!

I'm YOUR co-pilot? You're taking on more work just to bug me?

Rutherford: Y'know, if I quit my job in Engineering and switch divisions, I wouldn't have to be in the tubes at all.
Tendi: Really? You can do that?
Rutherford: Sure, when's the pulsar?
Tendi: 0800. AH! This really means a lot. I don't have a lot of friends yet and doing science on my own really bums me out so thanks, Rutherford!
Rutherford: All right. Looks like I just have to ... find a new career!

Well, if you see an unaligned EPS conduit, don't call me. Mine are aligned as hell.

Boimler: I'm going to be piloting General K'rin down to Talgana IV.
Tendi: K'rin... How do I know that name?
Boimler: Maybe because he's like one of the most decorated and battle-hardened Klingon warriors in history?
Mariner: Or maybe it's just cause all the Klingon names sound the same? Like they all have an apostrophe for some reason.
Tendi: Yes! That's it!

Starfleet doesn't just need badass cool people like me. They need, like, booksmart people like you too!

Mariner

Boimler: This whole time, I've either been one step behind you or totally in the dark.
Mariner: Yeah, but only because I'm pretty amazing.

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...
