Nah, they really watered down Ascended Astarion. Honestly, there should have been a scene, where he compels Tav not to go with Karlach to Avernus or with Lae'Zel. Instead, he is like: "You didn't leave me, I let you go". At this point, even though he still doesn't allow to break up with him, he looks like he really isn't even that much obsessed and he just doesn't care about Tav much (because, obviously, he is evil and very selfish, so he did let them go not because he really cares about helping Lae'Zel or Karlach, like Spawn does). He is making himself a whole army of other spawns, so like... whatever. His writing is all over the place in the end of the game. It's really-really noticeable that his writer left Larian.
