It's been a long time since he suffered this amount of pain at once, but maybe he has become more fortified in the past few weeks. Istredd does feel like the pain has spread so far into his body that it's even in his teeth, down to every nerve, it's just not something he is used to. But he is stronger than he looks. Enough to stand still.

"Yes, that is one of the upsides to being a mage." There is a cost. The major one, at least for some people, is the inability to have children. Once mutated it is incompatible with creating life. Istredd personally doesn't care about that, he doubts he would want a child even if it was possible. Yennefer feels differently.

"How old are you? I was assuming late thirties." Istredd hasn't gotten to the age where he can't guess correctly at that. After a few hundred years it becomes less clear when looking at people.

Istredd feels the pain still washing over him but the intense cleaning part has done and now he can breathe, slightly raggedly, the only real sign this was difficult for him. He is good at the stiff upper lip reaction. "That may be a lost cause if we end up having to escape again, but I'll try."

He leans forward to give Steve more of the space to wrap it. Istredd isn't certain they will make it through this. They have survived this long, but it's not looking great. "My main concern for us right now is that the logical thing to do with the back against the wall is to destroy the evidence and run." Them being the evidence.
