In the episode, titled “Last Reasoning of Kings,” Frank (played by John Benjamin Hickey) grapples with haunting memories from his past and his erratic behavior gets called into question, putting his team's loyalty to the test. Meanwhile, The Hill receives a special visitor in famed physicist Neils Bohr (portrayed by guest star  Christian Clemenson, of “CSI: Miami” renown), whose sudden arrival sparks curiosity among the scientists.

But our exclusive sneak preview is all about things going kablooey — and perhaps also offers a lesson in patience, as Frank learns why you should probably count to ten before running into an area where you just tried to detonate a bomb.
