I really wanna do a character analysis about Astarion regarding something I've noticed, and that's the fact that (I believe) his approval is related to the fact that he's only familiar with cruelty.
From what I've noticed, he doesn't *really* object to a good character. He'll whine about the extra effort, but you can get his approval almost maxed without playing an evil Tav (I've done so). And I've noticed that he's neutral to a lot of the "I'll see what I can do" dialogue options. He only really opposes things when you make promises, and I think that's significant.
I think he doesn't like promising to help people not because he's selfish, but because what if you can't? What if you're just giving them false hope?
I've also wondered if he approves of the crueler, more deceptive options not because he's a evil man, but because it's familiar. It's safe. He knows the world is cruel. Cruelty is predicable. Kindness isn't.
I haven't gotten to the hug scene yet but I think the reaction we saw in the trailer confirms things, that Astarion is really thrown off by Tav being genuine and that he's not opposed to kindness or softness - he just isn't used to it. When was the last time someone wasn't trying to manipulate or control him? When was the last time that he wasn't trying to manipulate and control someone else?
I think his romance is very interesting because he's so flirty and cocky and confident at the start but that's because it's purely physical and seduction and sex are what he is good at. If you sleep with him before the tiefling party, and then at the party tell him that it should stay a one-time-thing, he's really quite heartbroken. He plays it off, of course, but there is hurt there, real hurt.
Idk, it's just cool to see a character who isn't reduced to being evil for the sake of it - it's more of a trauma response and a self-destructive attitude because destruction is familiar and Astarion is terrified of the unknown.
Just some thoughts.
