I mean, you've met him. ( as to sum up all the things vance hopper is on the surface: ) He's angry. He's loud. He cut off Friday's head when she was possessed on Halloween. ( oh, right, natsuno hadn't seen that with his own eyes. uh. ) His hair's really big. He thinks "being cool" is important. And he's not afraid to speak his mind.

( and then, after a beat, to humanize him: ) He's scared. He's trying. He's worried about the revenants stuck in the Nothing. He can't spell, but was still willing to read books with me. He ( ... no, decidedly she won't tell natsuno everything. ) hates eggs. Wants the same thing we want. And one time he offered to punch a shark for me. I trust him.

But more importantly —

( then maybe the least sentimental point: ) He was very willing to walk away from what we're trying to do when he felt like you were purposefully keeping him in the dark. Let's not burn the whole bridge down just because it wobbles; let's instead focus on mending the most frayed ropes. I want to start with Vance, but you have to actually do it.
