More proof OP does not know half of Astarion's scenes or lore. He was not an adult when he "ended up with Cazador". Just leaving hints here for people who do not know what they're dealing with: this person does not know half the scenes, refuses to look at them, and does not intellectually distinguish concepts like synonym, group, and relation.

This is not an insult towards OP, but this thread has to be summarised by now.
