Lois and Clark continue to investigate Chloe's murder/disappearance; Lionel and Lex continue their blood feud; Lana returns to Smallville.

What's up with Lois: Clark and Lois investigate the charred remains of Chloe's safe house. While they talk about what happened, a helicopter flies over and drops off two commandoes. They attack Clark as Lois runs. Clark easily dispatches them, then uses his heat vision to disable the chopper. Lois fends off the final attacker with some impressive moves and the two run off. The next day she digs up her cousins grave and is relieved to find it empty. As she dusts off a man asks where Chloe is, when she tells him off, he turns his hand into a metallic blade and attacks her.

What's up with Lana: In Paris, Lana, looks at pictures from the caves and finds that her tattoo matches one of the symbols from their walls. When Lana returns to Smallville she goes to visit Lex. She'd like to rent the apartment above the old Talon... and she's not interested in anything to do with Clark. She meets Lois after saving her life by chasing off the man with the metallic hands.

What's up with Clark: Lana and Lois head to the farm and surprise Clark. He welcomes Lana home and learns of her "hot summer fling" from Lois. As he begins to confide in Lois about his feelings for Lana, another helicopter flies over the barn. Enter Sam Lane. Lois' father just happens to be a 3-star general! He's been keeping an eye on Lois, making sure she doesn't get into trouble.

What's up with Lex: Clark heads to the mansion to confront Lex about Chloe. He wants Lex's help but he still doesn't like him. Lex tells him Chloe's dead, but Clark spots a cigar that he knows is Sam Lane's and realizes Lex is lying to him. After Clark and Lois break into her father's office and find out that Chloe is being held under an alias, Clark rushes to the house she's suppose to be at. When he gets there he finds two dead men and his ex-friend Lex Luthor.

What's up with Lionel: Lionel threatens Lex's life while in prison, telling him he won't know when or where, but it will happen. However, it's the elder Luthor who's life is threatened when he's stabbed by an inmate while taking a shower. While in the hospital recovering, Lionel gets a visitor. Surprise, metallic blade guy works for Lionel! His name's Trent and he's looking for more money.

How it ends up: Trent hasn't killed Chloe yet, but Lionel convinces him to go back and finish the job. The men he killed were hired by Lex to protect Chloe. Turns out Lex engineered her fake death to protect her and since he couldn't trust the FBI, he called on Sam Lane to orchestrate her protection. Lex also put a tracking device on her and tells Clark where she's being held. Clark arrives in time to battle Trent, but it takes Lois' surprise entrance and help to finish Trent off, who explodes into a metallic ooze.

With Chloe alive and able to testify, Lionel is found guilty! The Kents tell Clark he should give Lex another chance, he did save Chloe's life, but Clark isn't buying it, Lex has always lied to him, and besides, the prophecy tells of one true enemy... Clark now thinks it's Lex.

In the caves, Clark finds Lana, who's looking for the symbol. When she gets back to the Talon, Jason is there. Lana only left him a short note when she bolted for home. He wants answers, she tells him she can't say why she's here and she still has feelings for him, but she can't go back. That's ok, he's not looking to take her back, just to be with her.
