Captain: Reason with the unreasonable. Stall.

You have one ace to depend on.

Captain: Son, you're stressed. Angry. And you got a right to be. This isn't fair. I'll agree. You did everything right, and it's still going bad.
Captain: Doesn't mean you gotta start doing wrong.
HeadOfSecurity: It's not about what's fair. It's about what happens if we retreat!
HeadOfSecurity: Did you go senile? You forget what's at stake here? The whole damn Company is the backbone of every inch of expansion in every part of the frontier sector. It props our whole damn galactic frontier society up and keeps it together, and you wanna let them knock that out?
HeadOfSecurity: You're puttin' our whole damn species at risk, in every system! Every planet! And I know how damn important that project is. If they get away with anything the Company has for that from the vault, we're gonna see a threat to everything. The goddamn apocalypse!!
Captain: I'm the captain of this station. You're the head of its security. Our job's keeping our own safe. Speaking mighty plainly, the Company pays people to solve existential threats, and they aren't us.
Captain: I'm not adding fifty to the casualties that they have to report when they solve it.
HeadOfSecurity: We've got an obligation to our damn species!
Captain: And we've fulfilled it. Tried our best. It was a good effort, son. You got tossed around near like a ragdoll, ChiefEngineer got blown the hell up and maimed, ChiefMedicalOfficer's been overwhelmed and terrorized, ResearchDirector got the shit kicked out of him, I got stabbed near to death.
Captain: We've done enough to learn that we can't do more. The whole crew would die if we stand and fight, and it'll have been for nothing but pride.

HeadOfSecurity: don't listen to this treasonous coward.
