Pepper didn't really want to go but the feeling of being practically useless was getting to her. She was used to running an international company not sitting idly by twiddling her thumbs. But here her skills were good for almost nothing. She couldn't fight and defend or build weaponry, she'd been able to help a little scouting of the area thanks to the scans JARVIS recorded when Tony took the suit out and about but it was a very small contribution in the overall scheme of things.
"I'm not sure" Pepper told him truthfully, "I don't even know if there is anywhere that could make use of me" she gave a wry smile at that. She doubted anywhere else would have the computer set up Tony had managed, and they definitely wouldn't have JARVIS, so even those skills were redundant.
