There's a little voice in his head, one that probably sounds like a lot like Carlos, trying to tell Thor that this is probably not a good idea. He knows Bucky can be ruthless, he knows what Steve is capable of and he knows that physically the other man is comparable to him.

Naturally, that makes it more exciting. It makes it much harder to step back and allow him to handle this when Thor, in his mind, has had claim of it since Tom washed his legs with hot oil.

"And you have done well." Thor retorts, posturing himself so that he's both looming to the full effect of his height and hunching so he can get in the other man's face. "Your mission ends here, Barnes. You know well why I lay claim on this." He has a consistent kind of volume to his voice that makes it resonate, he's not holding back on intimidation here.

Well. Not until he feels a tug at his spacesuit, anyway. He whirls around, as if expecting it to be Tom and not Carlos. His expression is momentarily apologetic, but he shakes his head. "There is no trouble here, Carlos." He assures, but that prompts him to cast a glance toward Tom on the ground. "Nowhere but here!" He declares, turning away from the scientist so he can approach the figure on the ground with purposeful stomps, aiming a kick toward his ribs.
