I definitely think Tataru is going to betray us or it could be something else. Maybe she's actually possessed by an Ascian or something. As is, they've shown Tataru to be weak and defenseless in pretty much every aspect, so that would either have to be a front or if she is really weak and just a spy that's been feeding information, they better give us the option to do to her what Raubahn did to Teledji!
