Crisis

S3 E16: Clark receives a panicked call from Lana and hears a gunshot before the line goes dead--but when he finds her, he is stunned to discover she is alive and well. After investigating with Chloe and Pete, Clark realizes that the events he heard have not happened yet, and Adam (recurring guest star IAN SOMERHALDER) is the person who will shoot Lana the following day. When Lex takes Clark to the LuthorCorp laboratory where Adam was being held, they find all of the taff murdered, and Lex suspects his father is responsible.
