Monica Reyes sold out. Oh, you can't exactly blame her. Having been told by a man who might as well be the devil himself that the world would be ending in the not too distant future, she made a pact to save herself. Immune from the plague that would wipe out the bulk of the human race, all she had to do was live with herself - and aid the very man bent on running mankind into the ground, whether it be to ensure he and those around him would survive, or because, frankly, he's a power hungry madman. Take your choice. In any case, learning that Reyes - a positive, almost hippie-like FBI agent who always seemed to be about positive vibes - cast her lot in with the devil, was certainly a shocker.
