GOING ROGUE

REVENGE OF THE ROGUES

Leonard freezes the door to a garage, and Mick drives through it. Once inside, the two step out of the car, Leonard commenting that he told Mick it would break. Mick asks where they are, and Leonard tells him that it's a warehouse for cars that are all worth a fortune. Mick asks how they're going to drive them all out of there, but Leonard says that they're not stealing anything. Mick asks what he's talking about, and Leonard explains that the silent alarms were tripped, and that the cops will be there soon. Mick says to bring them, and pulls out the case for his heat gun. Leonard reminds him that it's not for the cops, but The Flash. Realizing that The Flash isn't coming, Leonard decides it's time to leave. Mick tells him that things better start making sense, and Leonard assures him they will. They get in the car, and Mick reminds Leonard that he made him a promise, and Leonard assures him that he'll keep it. They back out of the garage and get away.
