While I would prefer that she doesn't agree to it and I think it's completely out of character that she does I never asked her to do it in the first place nor did I even consider asking her to have a threesome/foursome with Halsin or the Drow twins. As far as I'm concerned this doesn't even exist as I would never trigger this when I play the game.
Unfortunately I have to be the bearer of bad news. As much as I like the mindset of 'out of sight, out of mind' I'm afraid it doesn't really or fully work here. Or maybe it just doesn't work for me.
Because you see, Shadowheart flirts with Halsin during that one banter no matter what. So instead of rejecting his advances like you would expect her to, she instead welcomes them. If someone needs a refresher, this banter happens right after the romance is completed. Not before, not during but after. (So after the whole I want to spend the rest of my life with you/you are my true love conversation)
You are right that not having the foursome/fivesome/poly relationship is entirely up to the player and a players choice but what throws the wrench into this whole thing and ruins it for a lot of people are the words she uses and what those words imply. (if someone doesn't know what she says, look at my OP screenshots)
Like with Kagha, whether you discovered it or not she WAS working with the shadow druids an the same applies to Shadowheart. Whether you saw it or not she still has sexual thoughts and fantasies about Halsin while in a relationship with the MC (male or female) no matter what.
Like you said in makes no sense that she would say anything like that or be okay with it seeing how it contradicts her entire character, and yet its still there.

I love that you said this. It shows how obvious it is to everyone what the writer tried to do. And he was rather sneaky with it, wasn't he? Putting it all at the end, it is as if there are two Shadowhearts. True Shadowheart for her story/romance and a doppelganger made for Halsin.

So... what's the whole point of romancing her if she will probably just be thinking about the bear? I am just disappointed.
And there it is, the million dollar question. Why would anyone want to romance this character? Why would anyone want to romance Shadowheart only for her to do a 180 after he story was done. I don't think anyone likes the idea of going through 3 acts of 'I love you main character, you're my true love bla bla' only to be blindsided with a 'Sike! I was always thinking of Halsin.'
