Lois Lane is furious at lover Oliver Queen for leaving instead of waiting till she 'makes it worthwhile' but ignores he witnessed a thug attacking a couple and was badly wounded by the carjacker he fought off. Clark reads an article about the Green Arrow striking there and drops by finding Oliver uncharacteristically careless and irritable; his X-ray vision sees Olliver injecting himself. It's a wonder drug developed for Queen Industries by Dr. Pamela Black, which almost instantly restores damaged tissue, but the scientist advices in vain against taking significant doses because lab mouse trials prove a major aggressiveness side-effect. Lex is vehemently against Lana -whose health problems are soon diagnosed a happy surprise- taking charge of fund raising for a half-way house, without telling her his reason for fearing contact with its clients, even on few occasions: he bribed Dr. Black to administer the wonder drug to its problem youths, one of which was the car-jacker. Martha Clark insists to invite Lionel for the first Thanksgiving dinner after Jonathan's death.

Clark once again becomes "under the influence" of red kryptonite, and will say his true feelings on such things as Lionel and Martha's relationship, and Lana's pregnancy, but there may be someone else that will get affected by the red k.

After receiving a photo of herself dressing in her room, Lana realizes she has a stalker. After hiding out in Chloe's apartment above The Talon, Lana decides to hide out at another surprising location: the Kent farm so Lana can try to find out more about Clark as she grows more suspicious of his abilities. Meanwhile, Jimmy helps Clark try to find Lana's stalker in which he eventually breaks up with Chloe because he believes she isn't truly over Clark, forcing Chloe to take a deep look at her feelings for her best friend.

Clark has second thoughts about Lana marrying Lex, Lana starts to have the same concerns. Meanwhile... the doctor involved in the secret behind Lana's pregnancy threatens Lex with his knowledge.
