Saru: Natural phenomena do not disappear and reappear elsewhere.
Book: Doesn’t that violate the laws of physics?
Stamets: Every law we know of, that is.

Burnham: They need to be evacuated immediately.
Magistrate: Why? They’re criminals. Six offenders chosen to demonstrate the costs of misbehavior. An Emerald Chain tradition. It has proven most effective in preventing crime.
Book: Doesn’t matter who they are. They don’t deserve to die there.

Stamets: How do I work with someone who has zero respect for professional courtesy?
Culber: Let it roll off you. There are bigger things at stake here.

Stamets: Nice to finally meet you.
Tarka: Aurelio’s told me all about you. And, of course, I’ve studied your work extensively. So much to admire. And improve upon.

Kovich: What do you need?
Culber: Well, you’re familiar with my duties as ship’s counselor. And I saw how you were with Georgiou when she was in crisis. So…
Kovich: You need brutal honesty. Noted. We now have eight and a half minutes.

Kovich: You died. You died and came back to life. Little wonder you’re a mess. Your file is stunningly generic as to your feelings on this rather unique fact of your existence, so allow me to fill in some blanks. ‘Why me?’ It’s the question you ask yourself every morning and every evening. No one else gets a second chance so why me? That led you to the idea that there was a reason for your survival, a purpose you’re meant to fulfill, right here, right now. And that led you to a savior complex because if there is no reason, if there is no purpose, then your very existence is a middle finger to anyone who has ever lost someone. Which is everyone. How’s that for brutal honesty?
Culber: Do you have a recommendation to go along with that sparkling analysis?
Kovich: Whether or not you are a miracle, Dr. Culber, you are only human.

Culber: Well, I can’t just stop. Not now, anyway. It’s what I do. It’s who I am.
Kovich: It’s the way you escape the persistent guilt of being alive.

Reno: I can just picture Tilly’s face when she finds out we got sucked into a wormhole three days after she left.
Saru: I miss her too, Commander.

Great intellect can be costly.

Tarka

Tarka: Great science was never accomplished with caution.
Reno: I’m not sure that’s actually true.

Look, you may not like me, but I love me. And I am not going to let this experiment blow me up, which means, by extension, that your ship will be fine too.

Tarka

Go slow. The more you feed the monster, the more you need the cage.

Reno
