Mariner: Still happy to be here?
Tendi: Are you kidding? I got to hold a heart!

Doctor T'ana: We need to get this man to sick bay immediately. He is very important.
Captain Freeman: What makes him so special?
Doctor T'ana: Nothing. He's worthless. It's the slime, Captain. He's covered in slime that could save us all.
Captain Freeman: Everyone! Protect this slime!

Mariner: We've been serving together for a year and I still don't get why you worship those guys.
Boimler: They're heroes!
Mariner: All they care about is glory. Stuff that could earn them a mention in the history books. They don't really care about us.

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...

T'ana: The anesthetic is useless. We have to work through their pain. Your hands clean?
Tendi: Uhhh.
T'ana: Hold this. Don't pass out. Nobody's authorized to pass out!
Stevens: That's my heart! It hurts when you pump it!

Mariner: You've been on what? FOUR planets?
Boimler: Five. If you count Vulcan.
Mariner: Of course, I don't include stupid Vulcan. You may as well count Earth!
Boimler: I was... counting Earth.

I have served on five ships, man. I have seen stuff. One time, I got trapped in a sentient cave for weeks. You ever been trapped in a sentient cave? That's a dark place that knows things. I almost got my head taken off by a singing crystal. I've been in a Klingon prison where I had to fight a Yeti for my own shoes for NO reason. He was just being a dick.

Mariner

Hey you, green girl! Strap patients down as they come in. Double them up if you have to. They aren't going to infect each other twice.

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

Tendi: EEK! I can't believe we're going to serve, side by side. Scientists and commanders. An elite team.
Mariner: Yeah, no, we're not really elite. We're more like the cool, scrappy underdogs of the ship. Y'know, we don't wash our hands. We're doing kick-flips all the time...
