Talking about alternative endings for Spawn Astarion, I'd much prefer it if unromanced Spawn Astarion would go to the Underdark to help the other spawn if you let them live. From what I have gathered (which might be wrong) he currently always gets the hero-adventurer ending as a default and you have to jump through some loops to get the Underdark ending. Which is a shame. I liked his realisation that freedom means responsibility and that he maybe should go and help them, even though he really doesn't want to. It seems like a much better conclusion to his arc under these circumstances.
