I might be wrong, because I only have youtube as reference, but the Karlach-kiss isn't the Karlach-kiss anymore. They have an ordinary first spawn kiss now as far the the yts can be trusted and besides no I wouldn't want that one for spawn, it's beyond the discussion of player character's facial animations.

Besides Ascended got the 5 patch kiss back. It's the ultimate evil ending kiss now. It even got a new camera angle.
