[Oh no, that actually makes him feel sad. He knows Wirt thinks a lot of things that seem really silly to him. Things like people making fun of him, or not wanting him at their party, or not wanting to hear him play clarinet. But of all the things Wirt could think, thinking he's a bad brother is just about the worst.

He lets Wirt let go a little, but continue to pat him.]

I don't think you're a bad brother. And...nothing bad happened to be your fault! [He was the one who was goofing off when he was supposed to be leader...but he doesn't need to admit that right now.] I didn't get hurt or go anywhere dangerous, I just went to beat the Beast so you could stop being lost forever!
