Yep. i looked at those kisses and almost thought of going the fix him route this playthrough because they are horrible. I rerolled my previous game to test them out. In the end I just decided to never kiss him again after ascension so I don't have to deal with it.
They come out of nowhere and immediately after he goes back to being how he behaved before - they simply don't fit his personality or his actions and dialogue immediately surrounding them.
As far as I can see Larian have messed up Astarions Ascension ending completely with patch 6 and given the alternative is the 'lets live in the dark till Tav dies' ending - I'm even wondering why I bother continue playing.
I did send a ticket about them complaining about how out of character they are but hold no hope that anything will come of it. Someone at Larian wants to make the Ascended route truly evil.
