Pepper was practically required to go to all of the local charity events and she got an invite for the Frost annual fundraiser every year. She didn't have a lot of money to donate herself, but she always did what she could to help out. She would be hypocritical if she didn't. It also just so happened that Tony Stark had an invite to the exact same party because he had apparently dated Frost's daughter at one point in time. It wasn't a surprise to Pepper or anything, but she wasn't sure how she felt about showing up with him to such an event. Eventually they agree to just meet there and avoid the photo-op, but they still spent a lot of time at the event together and even had a dance or two.
Pepper pulled herself away from a boring conversation (leaving Tony to deal with it, thank you very much) to head to the ladies room. It was there that she overhead an alarming conversation. She wasn't sure it was any of her business or if it warranted getting involved since they seemed to be related and sisters would be sisters. Her conscious got the best of her though and she paused to watch for a second.
"Is everything okay here?" she asked. Maybe a polite interruption would help.
