To that end, do you think Yrene could heal more of Dorian? Do you think the Valg left something behind?

I don’t think the change in Dorian is leftover Valg necessarily. It’s more just the trauma of what happened to him. He watched Sorscha die, and then after the whole Valg thing he still lost his entire kingdom. I think that same change in character also drew him to Manon (or maybe it was another cause of the change). I guess what I’m trying to say is Dorian doesn’t need to be healed, because he’s just growing and changing as a person as a result of trauma
