FBI eager to help?
After they realised they were scammed into taking Shaw to court on Thanksgiving Day, Denham(FBI) comes to the conclusion that Shaw/apartment must be getting robbed.
Now previously he's been nothing but a shit to her, she knows he's guilty and wants him sent down but now knows he's getting away with it.
So why was she so fast and eager to get back to the Tower and stop Shaw from being robbed, you would of thought she would be taking her time so hes least getting some kinda punishment.
