Okay yep, that didn't take long: "I can go home. I really can..." but you're not gonna, you big lug, because you're in brokenhearted love with your platonic space crab engineer boyfriend and given a second chance at being selfless and sacrificing yourself for the greater good, this time for a planet of aliens that are unimaginably different from you (but also so much the same that you're in love with one), of course you're gonna run headlong to your death.

Still 50/50 on magically having the cake and eating it too, I don't trust that Weir has it in him to actually kill the dude off. Survival half is split into a 25/25 between going back to Earth vs permanent space suit and living out the rest of his days in crabville. "Rocky, you're a genius!" with a big sobby xenonite-bubble hug in either case tho.
