Powers, Principalities, Thrones and Dominions (2) - S1.E19

Attorney Al Pepper walks through a supermarket parking lot carrying a bag of groceries. A teenager, Sam, addresses Pepper and extends an open palm. Frank exits the supermarket and sees the two men. Suddenly, a bolt of light emanates from Sam's palm, knocking Pepper to the ground. Frank runs towards the scene, passing through panicking shoppers. When he arrives at Pepper's side, he discovers a handgun lying at Sam's feet.
