Keep your composure, Pepper--maybe he was more like Tony than she thought. She was here on buisness, and that alone. So why was he so concerned about how she was? He clearly had things to get done as well, so getting to the bottom of things as quick as possible seemed like the best solution. She stays silent for a second, thinking upon how to respond.

Of course he upset her-she was Tony Stark's girlfriend. And no matter how often he complained she tortured him somehow, she wouldn't let him suffer alone in this 'sanatorium' or whatever he assumed she was leaving him in. She may not be as smart as him, but she sure as hell wasn't leaving him alone to rot. That was insulting to her.

"That has nothing to do with the topic at hand, Mr. Holmes."
