That was one thing that threw me off about her character, I got why she was out in the "field" with Cape in the first episode as she was the only one that knew where he was to save him. But after that she seemed to be going out as often if not more than him, a significant change from someone that supposedly operated strictly from behind a computer.
I mean I had no problem with her trying to get more info on whatever situation they were dealing with, but it was a drastic change with no real explanation. Maybe she liked the initial adrenaline rush.
Although now that you mention the Chess' daughter part that explains where she got such nice cars in the first couple of episodes.
