What are the companion reactions like if you lose the duel with Orin and are doomed to succumb to your urge?
I've only seen videos of Astarion's, specifically romanced Astarion, so it makes me wonder if the other companion reactions are mid

I might test this by purposely losing on my current playthrough. Romancing Lae'zel on this one.
i'm pretty sure shadowheart's response is something like, "wow, it seems even your father has lost faith in you!", which is just a crazily insensitive thing to say lol. it's the same reaction whether or not she rejected shar, although i don't know if it's different if you romance her?
i do feel like several of the reactions to any version of the durge/orin duel seem inappropriately frivolous i.e. astarion's "twee" comment which really undercut what is meant to be a serious & moving culmination of durge's whole arc, for better or for worse. this isn't the case with any of the companion's stories, which all end beautifully, so it's a shame that durge's arc isn't treated with the same pathos.
