[Viktor nods, making an affirmative noise in the back of his throat. He supposes it doesn't matter what Tony said, and it's not as though he finds Steve untrustworthy. Everyone's going to have to cope with this in one way or another, and Viktor can't exactly begrudge how his friends go about it.

He doesn't stop Steve moving further into the workshop, though he does heave a sigh, as if recognizing the stubbornness and making it known that he won't be objecting.]

It's experimental, untested technology. [He doesn't want to put a percentage on it. Viktor believes in his own work more than most other things, but he has to be appropriately realistic. He can't get his hopes up.] It's just as likely to kill me as it is to cure me.

[A shrug, the implication clear.] I would rather take that chance, than weather the alternative, at this point.
