I finished Halsin's quest in the Shadowcurse and got what seems to be the dialogue for his new platonic path in the follow-up conversation. I put the log of both branches in the spoiler below with a little bit of the rest of the conversation for context. But this does look nice, doesn't it?

Friends and nothing more, then?
