Weaker did not mean incapable as far as Nebula was concerned, but softer - more breakable, in ways that she was not. She knew her own limitations and they went far beyond what she had seen most Terran's capable of, if her circuitry had not been damaged the night before she would have been fine to walk away from the tumble with the wolf without a second thought to it, a readjustment of her alignment would take care of it.
But Tony - he could not survive quite as much as she could. Though perhaps she would have died just as he had with the gauntlet. It was hard to know, none of them would ever have the chance to try it, and she couldn't help but look at him with that knowledge now - he was not dead, had not gotten to that point, but she knew.
He was alive though, fixing her up quickly and efficiently, the same as he had in those first days. And that was what truly mattered.
"Yes, it cannot happen the way it did last night again." She had not been fully functioning and even she had known the night had not gone well. Regardless of what had happened to her shoulder. "If we were all at our full strength the w- Remus would not have survived the night." And that was not an optimal outcome. He was a member of their community the same as she was and the loss of him was not something that should be planned on no matter what hardships it might cause to keep him there with them.
The color red would be new for her and she nodded, "Yes, I would like red." Adding to the patchwork of her parts, and this was a piece given to her directly from Tony, rather than those that had been scavenged from bits of armor after the final battle.
