Spoilers for the end of act 3 below.
Idk what happened. I’ve only ever helped her. We just came from the astral plane and are ready to fight the brain. She pledged her sword and I gave a speech saying everyone is the hero of Baldur’s Gate or some such, and then it cut to her telling me off and telling me if I die against the absolute it’s better than I deserve and she left. WTF? Does anyone know why that happened?
Edit: mystery solved. More spoilers below.
If you kill Minsc instead of saving him, and then don’t talk to Jahiera before the battle, she finds out about it after your speech, is hella pissed, tells you off, and leaves. She already pledged her harpers though, so you still get to use them.
Did you kill Minsk instead of saving him and then didn’t talk to Jaheira before the final battle? Because that will do it.
Yes. I didn’t even know I was supposed to save him. I made sure not to kill his little hamster though. Whoops! Mystery solved! I was kind of speed reading her statements in my last conversation with her. I guess I missed something. I was eager to tidy up loose ends and defeat the brain.
Next time just make sure you have non lethal attacks toggled on. Then when you smack him with your sword you can talk to him after.
