Martha is watching television on “Dark Thursday” and the recovery in Smallville as Clark returns home from his efforts to secretly rebuild the town. Clark is feeling guilty that he didn’t listen to Jor-El and Martha notices that he’s looking tired. Working on his chores, Clark has trouble pushing a nail into a board and then sneezes… blowing the barn door off its hinges. Out in the country, Lois is jogging when the barn door lands just behind her.

In Metropolis, Lex and Lana are driving and discussing her move into the manor. Lex notices a Range Rover following them but it turns off and Lex doesn’t mention it. Clark is still suffering from a cold and Martha wonders if he caught something when he lost his powers in the Phantom Zone. Lois arrives to tell them about the barn door and notices that their barn door is missing and resolves to look into the situation.

Lex confronts a private investigator, Robert Pontius, about the van following him, who knows where it’s based out of. Lex tells the man to take care of it, then tells Lana that someone has been following him and suspects Lionel, but hasn’t called the police. Lex gives her Pontius’ number to call in case of emergency.

Clark arrives at the Daily Planet to talk about his sneezing problem with Chloe, and setting off another burst of wind. She agrees to help divert Lois and sends Clark off.

Lex confronts Lionel, who denies having Lex followed and says someone may have seen Lex. Lex says he doesn’t remember what happened when he was possessed by Zod and refuses to accept Lionel’s help. Lex leaves in the elevator but it grinds to a stop and gas is pumped in. A gas masked figure drops in to take him away.

At the Kent farm, Clark is trying cold remedies. Lionel arrives to tell them about Lex’s abduction and ask for Clark’s help, warning that Lex might remember his activities during Zod’s possession and tell his captors.

Lex wakes up in a warehouse chained to a table, and the man who grabbed him, Block, demands answers from Lex. He knows Lex was at the Pentagon and had super-powers, and reveals he’s killed Pontius.

Lois takes Chloe to the barn door, where Chloe tries to pass it off as a mini-tornado.

Block is talking to a representative of his boss, Wagner, and it’s clear he’s got his own plans and wants Wagner to team up with him. Block shoots Lex in the shoulder to “test” his non-existent power.

Lois isn’t buying Chloe’s explanation and writes up an article on the barn door and wants Chloe to get it published at the Planet. Chloe passes.

Clark arrives at the manor to find Lana and tells her about Lex’s disappearance. She wants to know why he’s interested and wants to know how he knew Lex was going to transform before anyone else. Clark refuses to tell her anything and tells him to get out and start searching. After he goes outside, Lana calls Pontius and he listens in. He gets Pontius’ name from the answering machine and heads for his office while Lana accidentally finds Lex’s security recordings. After seeing that he tapes her, she sees Pontius’ report to Lex and the address where he found the Range Rover.

Block is still interrogating Lex and thinks his research may have given him super-powers. Lex tells Block the truth but he doesn’t believe it, and he prepares to shoot Lex again. Lex finally admits there’s a serum in a LuthorCorp lab and gives him the access code. Block sends Wagner to get it.

Lionel arrives at an office in a clock tower and meets with Oliver Queen, a rich millionaire who has relocated from Star City. They know each other and Oliver is a boarding school chum of Lex’s. Oliver reassures Lionel that he wasn’t involved and Lionel notes that Lex and Oliver had a bad relationship. Lionel leaves after warning Oliver off.

A weak and ailing Clark checks in with Chloe and they get Pontius’ address. They leave to check it out while Lana goes to the address Pontius reported and promptly gets caught by Block. Clark and Chloe check out Pontius’ address and Clark spots a hidden door but is unable to open it in his weakened condition. Chloe suggests he use his “super-breath” to bust down the door and he succeeds. They find the warehouse address and Clark super speeds off after refusing to take Chloe along.

Walters checks out the stolen serum when Block brings in the captured Lana and prepares to use her to test the serum. Lex warns the serum tailored for his blood type. When Block gets close, Lex head butts him and Lana gets the gun. She frees Lex before Block grabs her, but Lex injects him with the serum. Block sets off a fire, trapping Lex and Lana. Clark arrives as they try to climb out a hatch without success. Lex apologizes but the fire mysteriously goes out in a gust of wind and they’re left to wonder what happened.

Clark and Chloe are back at the barn preparing to go swimming as Lois shows up to announce the Metropolis Inquisitor accepted her article and she’s thrilled to be published. As she leaves, Clark blows away the rain clouds so they can swim.

At the manor, Lana examines the remote to Lex’s security monitors then talks to Lex about it. Lex explains the cameras are only for an emergency and she says they go or she does. Lex has the camera from her bedroom removed but refuses to remove the others.

Wagner arrives at Oliver’s clock tower office where he’s practicing with a bow and arrow. Wagner warns that Block went rogue and reports that Lex has no powers, but someone else was at the warehouse and had special abilities. Oliver sends Wagner to find him then fires an arrow into the Daily Planet’s globe.
