Not necessarily ending related since I didn't get there yet as Dark Urge, but to me it feels like good Dark Urge has some companion reactions in there that don't fit the choices you make at all.
I had the dream about being Bhaalspawn, admitted it to my allies and they were generally cool about it, telling me I could resist it.
I reach
Gortash and he tells me I was his partner in the whole Absolute plan until Orin backstabbed me.
I then talk to Shadowheart (romance), Karlach and Lae'zel about it and
Shadowheart/Karlach completely flip their shit at me. Shadowheart was sweet as hell about it in the end of act 2 romance cutscene and told me not to punish myself for my past, now she does it instead. Karlach acted like the signs were all there when I've been resisting it all along. Meanwhile Lae'zel just repeated the exact same thing she said when I told her I was a Bhaalspawn. And what she says highly indicates that I supposedly did not resist the urges. No chance to reply to any of them either, just straight back to normal dialogue. Yes Shadowheart, give me a kiss after you just shouted at me from the top of your lungs.
Companions in camp had nothing to say. Was a bit unfortunate, had hoped for more and more appropriate interaction.
