A cutscene will occur if Astarion is alive although it may be somewhat altered from what you may have previously experienced or been told. It unlocks a Character Ability. Increasing sufficient rapport is the main trigger.
Each player will experience it differently.
Each origin character has a second opportunity to be added to your camp if you left them alive during the first encounter.
There is information and encounters that if successful your Avatar will be aware Astarion is a vampire prior to the cutscene. (Hence why it may be altered - basically shortened).
The game has multiple opportunities for many things. Such as, besides the boar there is another animal carcass close that can lead to the same "encounter" if you do not interact with the boar. If you did interact with the boar no matter what the result was the other carcass will not produce the encounter and simply be corpse to loot. But still has information for you if you take the time to read its loots description.
