You got wounded in battle and were more concerned with interacting with Spinister than your wound. He was kind of scary- he was quiet and mysterious, but he was huge so it just made it him offputting and eerie. He didn't talk a lot but when he did, it was either with childlike whimsy and wonder or insatiable bloodlust and violence. He was an ace surgeon with some semblance of medical knowledge and everyone else was sleeping or eating so you had to trudge to his quarters and bother him. It was just a small wound but large enough to probably need staples or wrappings. He stared down at you, cold optics just... boring into your own. He raised his servos and tousled you around to look at your wound. "How did you get this?"
