Firo hesitates. He could protest that he had no idea Rey would even be here until she called him, and it would be true. But that sounds too much like an excuse, and making an excuse to this guy would be humiliating. Better to ignore it.

"So what? She's picked her side, and I've picked mine. She can hold her own, and I'm only hitting him, anyway."

He hopes, in the long-run, that what he's doing will help Rey. If he has an in with Sato, he might be able to keep the guy away from the ones he loves when things really go south.
