I just saw it again in all 3 variations. Yes it is far better than before, but
All 3 variations are the same, everything looks like this scene was taken somewhere from the removed content and it was not meant as epilog, but just some quest cutscene from avernus location. 1) Tav and Karlach romance - it feels like they are just friends, not lovers, there are no emotions and definetly there is missing al least something, that they are together in love. (not speaking that one minute before she almost died and they talked about how much love each other) 2) Tav + Wyll + Karlach - Wyll is added behind Tav an Karlach and is speechless and Karlach said the same things as in first case, again empty and without emotions 3) Wyll + Karlach - this looks best of all 3, because it feels like they are just buddies and they will enjoy killing demons.
Again and again hoping for the future complete quest line with heart fix
