Tony was looking at her. He had taken the asprin. He knew that was probably a wise idea before any meeting. He was sure he would still feel pretty damn awful for a few hours at least. He didn't seem to have noticed he was mad before.
"Ah I am not hungover... I was just up all night. I'm working on things." He knew that he probably couldn't deny he was hungover. He just didn't want another lecture about drinking. He was grinning a bit.

Tony was looking at her "Ah I didn't hear." he replied. He knew that he would have been up earlier if he heard her call. He decided to just remain quiet for the rest of the trip. he wanted to avoid saying too much and upsetting Pepper.
After awhile something caused the rage to return.
"Happy!!!" he growled "We are in a rush here."
The man was seeming tense. He again wouldn't remember losing his temper.
