It's an NBC show, so don't expect much. The writers either don't know how government works, or they just don't care. When the Deputy Director of the NSA is running around doing his own field investigations and making arrests, you know you're in complete BS Hollywood fantasy land. There are more holes in the story than a colander. A plane reappears after five and a half years missing and the majority of the public doesn't seem to care one bit. In mere days, the characters are back to their normal lives, worried about their jobs, their old lovers, and no body really cares what happened to them. Don't bother.
