Plot hole: The CIA is desperately trying to find Pope's contact, to the point of doing the crazy experimental brain surgery shipping over the ocean the one scientist that may perform it, and an inmate. But they don't have Pope's house under surveillance or his phone tapped, so they have no idea Strook called him. The fact that Strook not hearing back from Pope would try to contact him was quite literally the most obvious possible event. (00:31:00)
