Cal grinned widely. There it was, that name again. 'Duo'.... she mused. She wondered if this 'Duo' was the reason OZ didn't trust Ivalia completely yet and had set her up to do a tap on everything possible in the girl's house. Track the emails, tap the phone, put bugs in every room of the house, hack the computer, do everything but come right out and ask her if she was really loyal to OZ.
Apparently OZ didn't want to trust her assessment of things. Not that she would in their shoes either but still. Just because she could do all this stuff didn't mean she didn't feel the urge to just go and find out without all the subterfuge.
And she would have, if it were only her at stake. Sure, her brother had proven that he could take care of himself quite well, but Cal wasn't going to force him into a defensive position because of something she did.
