Clark receives a panicked call from Lana and hears a gunshot before the line goes dead, but when he arrives at the Talon he is stunned to discover she is alive and well. Clark realizes the phone call came from the next day and that Adam is the one who will shoot Lana. Upon taking Clark to the LuthorCorp lab where Adam was being kept, Lex finds all of the staff murdered and suspects his father is behind it. There was no redeeming qualities in this episode whatsoever. It was way too dark and, to make it worse, the time warping wasn't explained. Time travel is the hardest thing to explain plausibly in science fiction, which is why time travel movies and episodes generally makes no sense. I prefer to watch other types of science fiction.
