SO my TAV and her LI only had eyes for each other and the party arrived at Sharess' Caress. The Madame makes them an offer and they could not be less interested but Karlach SPRINTS to the back room. The brother says he thinks he would be too much for Karlach. Karlach!?! But the others arrive and my TAV tells them about the offer. Now, I know what happened next because I get to tell the story between the dialogue trees, but in game it would be wonderful if there was an option for another party member to go and play. Maybe add a little interest and risk by removing them from the party until a long rest? No cut scenes, just gone. Do you let another companion take up the offer but in return you are down to 3 until camp?
Anyway, Karlach did eventually catch up to us in Baldur's Gate.
