Shocking, I know. She offered an "anything you want, no questions asked" deal for the release of Ms. Lewis and was of course called on her bluff with the task of killing Mr. I'm Not Daredevil. Which she immediately refused and was punished for. Sloppy work for a spy.
Still doesn't answer how she wound up in the bunker, but I suspect another deal was made that nobody is laying claim to.
Probably best, can never be too careful with children.
