Lana and Genevieve fight to the death; Jason returns; Meteors head towards Smallville; Clark must give Jor-El all the stones to save the town; Lex and Chloe witness Clark vanish; Lionel goes into a coma.

How it begins : Genevieve confronts Lana in her apartment. The two fight and Lana kills her by plunging one of the stones of knowledge into Genevieve's chest. When she looks up she sees Lex standing in the doorway. Clark has a nightmare and wakes up screaming "it's coming." A meteor shower is headed Earth's way.

What's up with Lex: Lex comforts Lana and tells her she can't go to the police. He'll help her get a great lawyer and deal with the crisis. Later, Lionel shows up and blackmails his son. He wants the stone Lana has and if he doesn't get it, he'll turn Lana in.

What's up with Lois: Lois informs the Kents that she's heading to Europe to try and find her sister. She helps Clark get ready for graduation and the two make up for all their bickering during the year. Clark tells her she should go into journalism, but she has no interest.

What's up with Chloe: Clark and Chloe graduate, but Lana doesn't show up. Half way through the ceremony the national guard rolls in and tells everyone a meteor shower is coming and they have to evacuate immediately. Chloe and Lois go looking for Lana.

What's up with Clark: Back at the farm, Clark tells his parents he has to be the reason the meteors are coming again. He has to do something. Before he can, Lex confronts him about the caves. He's found a hidden room and wants to know if Clark knows about it (knowing full well he does as he stole some of Clark's research to find the room). Clark tells him he doesn't and Lex leaves knowing Clark is lying to him. Clark goes to the caves and talks to Jor-El who tells him mankind awakened the trouble by getting the stones. The only way to save Smallville and himself is for Clark to get all three stones of knowledge.

What's up with Lana: Clark tells his parents he has to stay behind and combine the stones. They reluctantly agree and he heads into the barn where he finds Lana waiting for him. She gives him the stone and tells him she loves him. He replies he loves her too, and then, asking him to trust her, Lana turns and leaves. Lex tries to get Lana to give him the stone, but she refuses.

What's up with the Kents: Martha and Jonathan (and Shelby) are about to leave the farm when Jason pulls up bloodied and upset. He pulls out a shotgun and demands to know where Clark is.

What's up with Lionel: Clark places the stone Lana gave him next to the one he already had in the cave. As soon as he does they both glow and so does the one that Lionel has in his coat pocket. Lionel has a seizure and is incapacitated. Lex puts the stone in his safe. Clark is able to follow a piercing noise to the stone, but when he grabs it he's affected by all the kryptonite in the artifacts around it and he falls helpless to the floor.

How it ends up: Jason holds the Kents hostage and demands to know where the stones are. Lex finds out Lana doesn't have the stone anymore and puts her on a helicopter to Metropolis. Chloe heads to the mansion to try and find Lana and instead finds Clark unconscious on the floor. She drags him away from the kryptonite and he super speeds away just as Lex walks in. Chloe says she's looking for Lana but Lex notices the stone is missing and demands to know who took it. Chloe feigns ignorance, but Lex sees thought the lie and drags her to the caves.

Jason is about ready to kill the Kents when the meteor shower hits. The farm house is hit directly, with Jason and the Kents inside. Clark is able to save some people, but the town is hit hard and several people die. The helicopter Lana is in is hit and crashes into a field.

Clark makes it to the caves and places the final stone in place. It forms a diamond shape and levitates into the air. Chloe pushes Lex down and witnesses Clark grab the shape. Lex gets into the room just in time to watch a flash of light, and Clark disappears. He reappears in an Arctic snow field with nothing but snow and mountains in sight. Clark hurls the stone across the horizon.

Lana is alive but injured and crawls to a crater that contains a large spaceship in the same diamond shape as the now combined stones.
