He wasn't being paranoid, he was being realistic. Tony didn't get paranoid; being paranoid meant being unreasonable, and his contingencies were always based on scientifically accurate predictions. Scientifically, Pepper was scatterblasting this whole office and didn't even feel bad about taking the show on the road. How was anyone supposed to get any work done in those conditions? "You're not heading it off, you're infected," Tony was already saying before she could even get to the 'paranoid' part, effectively proving the insult invalid. "Are you handing me drugs?" he still took the opportunity to say, as though she was passing crack cocaine across the desk to a known addict in an admittedly dirty move to shame her for the behaviour. Maybe then she would see how unreasonable she was being.

You're paying a lot of people a lot of money for the privilege of doing their jobs. The holo thing is done, that's my department, here's the catch up: it's covered. Okay? Done deal. Good talk. Don't screw this up, some people still aren't comfortable with this arrangement and I already read better on camera, you're just going to look worse if someone catches you with the flash on that redness," he insisted, with a vague gesture around his face that was supposed to be for the sniffles that were irritating her nose, but really her eyes weren't looking so healthy, either.
