I didn't had a scene with multiple companions yet, but sort of a 3 person banter during exploration.

First Wyll hit on Laezel, got semi shot down (
"I do not believe in love."
"Oh..."
"Carnal Pleasure on the other hand..."
"Oh!"
) and then later flirted with Shadowheart who was angry that she was wad the 2nd choice and that he should pay attention who is within earshot when he tries to pick someone up
