Twenty Hours Earlier... An intense light wakes Lex Luthor just before the day shift is due to start on day 501 of his time in the Metropolis Maximum Security Prison. He scrubs a hand over his face, trying to remember what his latest nightmare had been about, before deciding he'd rather not recall it. He's struggling to get his prosthetic fitted in place when his door reverberates as if a mighty blow has hit it. He's startled and wondering what on Earth is going on, when the door buckles inwards, then drops to the floor, and he finds himself staring in absolute disbelief at the figure standing in the doorway, moving into his cell.
