For reasons somewhat related to but also entirely separate from the Halsin problem, I don't think I'll be planning to bring Shadowheart with me anymore (and may be dropping her from what, for now, will be my last playthrough of BG3 until the Definitive Edition). My question is, does Halsin still have all of this... gross stuff go on with him, if you don't bring Shadowheart, don't romance anyone else, and don't talk to any of the Caress courtesans in Act 3?

Other than the gross "poly" talk, obviously. I know that is sadly unavoidable. But, I could deal with it if the rest of his veritable mess disappears from neglecting to take Shart with me.
Shadowheart shows no interest in Halsin if not romanced. Halsin shows no interest in Shadowheart when he is solo romanced or not romanced at all. He doesn't try to join as far as I know in drows encounter, because he proposes himself as 5th only if you romance someone already and they agree to do foursome.
