and it's not you.

When you kill Isobel and Jaheira comes at you at Last Light. She curses the Bhaalspawn, and gives one of the best scenes in the entire game by far. You can have her survive this scene if you can pass certain checks (I used intimidation to get her to run).

Then in Act 3 if her and Minsc are still alive, when they gather their allies and come to get you after you bathe in divine blood at the temple... That's another amazing scene, and it's really where it's fully realized by the player that you are absolutely the villain of this story. Jaheira is Baldur's Gate's hero, she just died on the second end boss (you).

Even if you're doing a playthrough that allies you with her, her speech before you march on the brain is top tier. Basically, this is just a Jaheira appreciation post, I'd love a DLC where you play a Dark Urge story but from the perspective of Jaheira as the protagonist. Not a difficult DLC to implement imo.
