Firo's not used to talking his way out of anything. Right about now would be when he'd try to bait the person accusing him, get them to throw a punch so that they could fight. But he's pretty sure instigating a fight with Sato wouldn't go too well--not for Firo.

He narrows his eyes and shrugs one shoulder. "I can't tell you what to think. I can tell you that I couldn't do anything about your escape--I had no idea what happened to you. You think they'd tell me what they did with you?"

It's a not-so-subtle way to try to remind Sato that they're on the same side. Firo's a problem for the Guard, too, remember?

Firo lets his right hand drop to his side; it's still relaxed, but from here he can be ready to move. He's afraid he may have to be.
