"...That's a fair point." It certainly could have been a spat. The Suou flight response is probably the worst possible way to react to this sort of situation. Save, you know, turning aggressive. He left. Katsuya can't deny that. He didn't want to argue. But walking away, well, that was an argument all by itself really.

Just a nonverbal one. And a choice he has to live with.

"I'd rather discuss the details with Verity, than to gossip." He doesn't even know what to think, anymore. So much of what she said came out of nowhere to him. And he reacted poorly. Shut her down. Walked away. It's something his brother would do, and that alone is a telling point of how pear shaped this has turned. This time he does sigh. Heavily.
