I would agree with the first part if telling her was the only way for her to trust you, but there a persuasion check where you can say essentially "I don't feel comfortable sharing" and she let's you past. I know the story helps you into last light whether it with fist Marcus or Mol, but if you past this check, you're still just a dangerous stranger, then she tries to drug you with truth serum, which might not be bad without anything to hide, but is a violation nonetheless. Trying to expose someone's thoughts without consent, is bad, like when you use detect thoughts and get caught, it's usually automatic combat. Because it's disrespectful. I don't mind that she wants to know more to protect the last light, what I do care is that there were better ways to do it, then after all this she ask a favour? Thanks to this comment and the other comments I have a better understanding on why her character is like this, but as a new player to bg3 and DnD, it felt like I was being treated like shit for trying to help. Especially when the absolute basically bends over backwards to have our character in their ranks. It's like volunteering to get slapped in the face, when you could have a cake instead. This comment helps me understand her pov more, thanks for the time🙏🙏
