His throat dries out completely when Thor turns and sees him, at least it feels like it does. He tightens his grip on the blade slashing wildly at him as he approaches him, hoping to give him at least a pause. The last time they met plays on Tony's mind, he knows it won't make Thor stop, but he's clutching to a hope it might.

They've done something to him to make him like this, he doesn't want to hurt Thor or make it worse, but right now all he can think about is getting Thor away from Bruce.

"Little beneath you isn't it? Taking out the harmless scientist?"

He knows Bruce isn't harmless, but really goading Thor seems like the right option right now.
