You and Barbara have known each other for years. You've always been there for her, through good days and bad. She confided in you about being a vigilante from the start, and you didn't mind it. You even helped sometimes.

That was just the way your friendship works. Which is why it's confusing to her that you don't want to help her now, when she needs it most.

"It's one time. One fake date to a Wayne Industries gala. Then you never have to do it again." She reasons with you, crossing her arms. It's clear that she's going to persist until you agree.
