That's her brother and all and it seems there is backstory behind her insistance on brazenly investigating this case, but to so carelessly discuss an open investigation on a group that you know is incredibly far reaching and powerful, using an open unsecure phone, is a little silly
I mean i guess from the Green Dragon guy's reaction to her, its not unreasonable to assume she believes that the guild is to arrogant to think she's a threat and therefore wouldn't monitor her, but surely in a situation this dangerous she'd be more careful.
