So,,, if elves can live up to 750... then Astarion's parents may still be alive if they had him young. They'd be old as hell, but alive. And they'd have mourned their murdered son for 239 years, not knowing he was undead, a vampire, and being tortured. They'd have been visiting an empty grave. And never knew it was empty. So potentially... if Tav was sneaky enough and did some digging and found out where they lived... they could reunite Astarion with his parents. His old, elder elf aged parents. Who would see the 39 year old son they'd assumed dead 200 years ago at their doorstep. See those fang wounds and the red eyes and just... know.
The truth about Cazador would have gotten out eventually after his downfall. They'd see their now vampire son and immediately know what had happened to him, that he'd suffered for 200 years. And now he was free, deeply traumatised and a changed man. But still their son, still looking 39 like the day he died, back in their arms.
And some stranger they'd never met had cared about him enough to find his parents and bring him home to them. Astarion finally could bring his *true* lover home to his mum and dad. And his parents could finally rest easy knowing someone cared about him and loved him as much as they did, to the point they went out of their way to reunite them.
