Does he count as her kin now, after sharing dragon blood? At least I'm sure he's a swordsman now and not "just" a healer.
I'm a little concerned about his childhood friend. I'd hope all of them see each other outside the dungeon, but I feel like she'll be artificially separated from him for as long as possible with every kind of annoying misunderstanding thrown in.
Get married already, human lifespans are extremely short compared to dragons. Better enjoy every minute of it for her sake.
