I agree with all of what you wrote @SteelTempest. To me it also seems as if the writers tackled the brothel scene with different levels of seriousness. In Gale's case the dialogue leading up to "the scene" is quite interesting and even adds another layer of meaning to the act 2 romance, especially if you chose the bed-in-the-woods version because it shows how much he trusts you and your relationship. It's a lovely way to use an uncomfortable situation to show another layer of the character and I am very glad they changed the player dialogue for this portion of the scene.
The orgy scene itself also makes me appreciate Gale even more but at the cost of being thoroughly disgusted by Halsin and my own character. While I can retcon these feeling in regards to my own PC for something that I only tried for science anyway, the bad feeling about Halsin's actions lingers, which is both unfortunate and most certainly unintentional.
