Let me see if I have this correct, Lieutenant - it's an 8-foot creature of some kind with acid for blood, and it arrived on your spaceship. It kills on sight, and is generally unpleasant.

When they first about heard of this thing, it was "Crew Expendable"; the next time they sent in marines, they were expendable too. What makes you think they're gonna care about a bunch of lifers who found God at the ass-end of space? You really think they're going to let you interfere with their plans for this thing? They think we're crud, and they don't give a fuck about one friend of yours that's died. Not one.
