The kissing animations do not mean much to me, mostly because I will never see most of them in my gameplay. There are other animations, however, which I thought were brilliant. For example, when Karlach gets her first hug after getting a dose of iron ... that was a perfect scene. And I do like Astarion in just about any animated scene.

I wonder, hey isn't this backwards? What is Karlach thrusting with if she doesn't have a ... oh wait a minute, she does have a spiky tail .... oooh nooo! Argyle now wears a Chastity Belt +1, encrusted with frost.
