He's angry that she's still upset. He doesn't understand why she's making a big deal out of this. At the same time he's angry at himself, not being able to convince her he's sorry, for being unable to say anything more, for not responding to her later. Then there's shame, that he's hurt someone that hadn't wronged him and that he's angry at her for honestly expressing herself. He doesn't know what to do or how to make this right or what the right thing to do even is! He's just so sick of this place and these people and not being able to understand any of it.

His grip on Susan's shoulder is tight. His other hand clenches into a fist. He wishes he had his staff if only so he had something else to focus on, but he doesn't. The worst part is what she's most upset about is that he'll hurt others, but he already has, and he still wasn't completely sure he was in the wrong in attacking them either.

"I'm trying my best."
