Hello! Nice to meet you! I admit I know very little about Arcane, but I did once see someone on Twitter say that Jayce and Danse are "the same guy in different fonts," so if that's at all accurate (or even if it isn't) I'm sure they can have some good talks.

Danse is always going to be drawn to other people who have clearly Been Through Apocalypse Shit, so that could be a great way to get some CR going, depending on how it comes up! And he has no idea how serious the monster transformations can get, either (or...that they will be happening at all, actually, at this point) so that can also be a very useful conversation if he doesn't immediately assume Jayce is a ghoul.
