"I do," She agreed - she wouldn't have come to him if she didn't think that he could help to fix her. In truth she likely could fix herself if she had enough time - but it would take her longer and it would be far more uncomfortable. And she trusted Tony. She knew what he was capable of, and he'd helped in the past.
As for the pain - well she might be made of more metal and wiring than most but she did still feel. And this did hurt. "Not as much as it could." She said after a moment, it was not an unbearable amount of pain - say what you would about Thanos, but he had taught her how to bear pain better than almost any other in the galaxy. So this was but a small thing in the grand scheme of the pains she had experienced in her life.
"How is it?" She asked after a quiet moment, "The wolf?" It was still a strange idea, the idea of a man turned animal like that, there were of course stories of transformations across the galaxy, but she had never seen anything quite like what they had experienced the night before. And now that she had, she thought that the once was likely enough for her.
