"Yeah, I guess that makes sense," Still he sounds a little disappointed Cesar can't offer him more than that. Not that Tony doesn't understand, but the occasional hopeful flight of fancy is a nice thing to entertain every now and then, especially in the face of crisis.

To the repeated question he shoots Cesar a flat look. "Dude, I healed up a dissolved eye," He tugs up his shirt where once there was a nasty scar from surgery. No longer. "Even my surgery scar's gone, I think I can handle a couple blood tests. What are you really askin' me?"

There has to be a reason, mister logic that Cesar is makes his line of questioning suspect, when the evidence is more than enough to show that a little bit of blood isn't going to hurt Tony any.
