Well, I didn't want to reveal everything about my character. In my CS it says how she basically doesn't look out for no-one else but herself. And I was gonna have her character be the type of girl that's willing to do whatever she can, even if that means manipulating people, in order to reach her goals.

I planned on letting that be kind of a secret about her personality and I mentioned it in my post. In order to build character. But, if it bothers you still then I'll change it. And she can tell that your character is lying because she herself is great at lying. So, she had trained herself to recognize these things. That's part of her trust issues. Someone lied to her in her past so she's doing her best to learn to catch lies in order to know who she can trust and who she can't.

Sorry for any confusion.
