Given that Astarion in Act 1, to Tav's words that if he tries to kill, will take you with him, replies, oh, you have fire in you! - don't get mad. Laughs when Druge says how he's going to take over the world and shake it. And then says, to his spawn, you'll drink my blood too. Which could be a Kin-Nectar reference. The blood itself doesn't turn the spawn into a True Vampire, apparently Astarion got splattered with Cazador's blood. There must be a clear intent. I was expecting something like that from the kisses. But not the victim's terrified face being pushed away.
From my observation, AA's target audience is Morticia Adams, who will carve her lover's name on her ankle herself.
