Idk if it would make sense but there is a cutscene we can unlock if Astarion is kidnapped by his siblings and then he is with Godey...
After the cutscene,Astarion just returns to camp and talks about it.
It would be amazing if he scapes, only if the player had a hight aproval or romance with him, we could hug him because of how worried tav \ durge would be.
Or tav\durge hugs him first or he does it.
Idk.
Maybe It would depend on the level of aproval and \or if we romanced him or not.
When I got that scene, that is what I imagined xD.
