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.
