A simple and very common mistake was all it was.

"Their version of me isn't such an alright guy." Not that it was his fault. That Heero had been tortured to be that way. It didn't take much effort to win the others over, not that he had tried.

As for "Loudmouth", Heero couldn't help but smile knowingly. He knew exactly who she was referring to and yes, he did have a loudmouth.
