I just finished my Durge playthrough romancing AA and I don't think I have ever seen Astarion as happy as he did in the ending cutscenes. *clap* I freaking loved it. *clap*
I'm happy you got to see the end and the Durge playthrough
He's obviously so happy to have his Love with him and is excited about their future together hand in hand. The only thing out of place are the awful kiss animations and this need to be fixed. They are a stain on an otherwise fantastic experience.
