So if I'm not the leader, how does Shadowheart dare to blame me for not taking her into the Nightsong prison, or Lae'zel for letting the Emperor kill the Prince? If they're so independent, then Shadowheart can go fight the Nightsong herself, Lae'zel can go fight the Emperor herself, and she can go die for her beloved Queen in that brain extractor herself. Let them handle their own mess without me. It's like your friend blaming you for not helping him get a job, and then blaming you for him becoming homeless.
Astarion and Shadowheart even make fun of your leadership role a bit. That's not what you do to your revered leader, it's what you do to your buddy who's maybe a bit too full of himself
Astarion's existence literally depends on me - and yet he mocks my leadership role. I'd have serious issues with people like that in real life. They would instantly take a direct chartered flight to GTFO and stay there permanently.
