Lois writes the story and does everything she can to protect her source, even after Eric Thorp (Tim Grimm), the CEO of Stuart's company, tries to kill her and forces Stuart to say that he was lying. Perry is forced to kill the story while Stuart, who has been hiding at Clark's place, disappears.
The disappearance looks like Stuart has been murdered and Lois is suspended since the murder was a result of Stuart providing her information. Clark helps Lois to restore her reputation and they discover that Stuart is not dead but he staged his death with the help of his best friend Oliver (Jeff Joseph), so people would leave him alone. They find him and convince him to help them expose the truth. Thorp is arrested and Lois returns to the Daily Planet, having restored her reputation.
