Changes

After getting a [[Hyperbolic Pulse Generator]] from [[Arthur Ketch]] of the British [[Men of Letters]], the Winchesters, [[Castiel]], [[Crowley]] and [[Rowena]] team up together to return [[Lucifer]] to his cage. Using [[President Jefferson Rooney]]/Lucifer's mistress [[Kelly Kline]], the group lures Lucifer to a motel where Sam uses the Hyperbolic Pulse Generator, a device capable of expelling a [[demon]] from their [[vessel]]. The powerful pulse beats Lucifer back, as Rowena casts a spell to send Lucifer's essence back to the Cage. After exchanging words with Sam, Lucifer vacates the president's body, his essence swirls below the ceiling before going through a heating vent in the floor.
