"Why go out of my way to be a bullshitter when I've been accused of being one for telling the truth all my life?"

Little bit of a bitter moment, there. It didn't last long, at least. There was a conversation to get back to and a giant green dragon to distract him from most of that.

"I can see... things. Things that most people can't see." He looked back up at the sky. At the dragon. "I used to think it was just ghosts. And then I saw something that happened three centuries ago and started yelling about talking trees in front of the entire town."

He was possibly not doing much here to make a case Re: being sane.
