Ivan looked at Warner, a slight quirk of his eyebrow, not at the "Pretty boy" but rather of the question, he says calmly
"Well, that is a split question, my comrade is dead in either case, and if theres a chance of survival without diverting to a barbaric, yet perhaps needed act of animal nature. I'd personally wouldn't do it, I would try to ration the food rations to the slightest and survive on water from the surrounding environment. You mentioned it was a Tundra world, I could survive on water alone for 8 weeks. That is an fact, now that doesn't include the rationing of what ever food I have. Since I presume that a search party would be looking for us after 2 weeks without contacting them, i'd presume i'd survive.
But, in the extreme case that I wouldn't survive, i'd record all data we've collected on the planet..
To finish, I would not desecrate my comrade's corpse, even if it meant my life."
Ivan's body stiffened as he tried not to imagine the situation.
