What's up with Lionel: Lionel is still in prison. But since Chloe's dead, he'll be out in two weeks. Lex stops by to visit and he accuses his father of hijacking his plane and stealing the crystal, who else could pull that off? It's revealed the crystal is one of three that when combined point to a vast treasure that contains more knowledge than the world has known.

How it ends up: Bridget Crosby calls on Martha. She's Dr. Swan's assistant. Martha is reluctant to trust her, but finally confides in her what's been going on. She did call for help after all. She tells Martha she must face her son to win him back. To help her, she's given black kryptonite... she's Clark's only hope.

Kal-El goes to the caves and enters a hidden room where he places the piece of crystal. When he emerges from the room, Martha is waiting. She touches him with the black kryptonite and proclaims her love for her son. Clark and Kal-El split apart and begin to battle one another, Martha throws Clark the black kryptonite and he plunges it into Kal-El vanquishing him, if only for the moment. As he does, Jonathan wakes from his coma and Clark falls into his mother's arms.

Lana wakes up in her bedroom, but doesn't remember how she got there. She missed her meeting with Jason, and while showering she notices a strange tattoo on her lower back... it's the symbol from the tomb!

Lois brings flowers to Chloe's grave. While there, Clark shows up and the too bond over their love of Chloe. Clark offers the Kent household to Lois while she's in town as well as his assistance in tracking down Chloe's murderer. Lois accepts, but while she's walking away Clark uses his x-ray vision to look into Chloe's EMPTY coffin! Wait! He says, Chloe's still alive!

Clark returns to Smallville re-programmed as Kal-El. Intent on fulfilling his destiny, Kal-El takes to the skies to steal a powerful kryptonite crystal. Determined to save her son, Martha turns to Dr. Swann's emissary, Bridgette Crosby, and learns about a surprising new form of kryptonite. Meanwhile, Lois Lane comes to town to investigate the murder of her cousin Chloe. Also, Lana returns from Paris with a new attitude and a new boyfriend, Jonathan lies in a coma, and Lionel faces a grim new life in prison.

Lois (upon seeing Clark naked): Look at his face.

Clark: Wait. Who are you?
Lois: Lois. Lois Lane.

Lana (to Jason): Well it sounds like love at first crash.

Lana (to Jason): If a guy did something that romantic for me, I think I'd have to kiss him.

Martha (about Jonathan): My future is lying in that bed. I will not give up on him.

Lois: Were (Chloe) and Clark ever an item?
Martha: Maybe for a minute...

Lois (to Martha): I guess I'm a sucker for stray dogs and naked men.
(Martha stares)
Okay, that didn't come out right...

Dr. Vaughn: What's more important than your life?
Lex: The truth!

Dr. Vaughn: You're living on borrowed time, Lex - stop trying to borrow more.

Jason (to Lana): "Okay, when my girlfriend invites me to some old crypt for brass rubbing, I thought it was some kind of code."

Clark: What is this place?
Martha: Your dad calls it your fortress of solitude.

Clark: I am Kal-El of Krypton. It is time for me to fulfill my destiny... Clark Kent is dead.

Lois: I never thought (Chloe) would fall for the farm boy type.
Martha: That can happen to the best of us.
Lois: Not me. Give me a nerd with glasses any day of the week.

Martha: Clark has many sides.
Lois: I know, I've seen several already.

Lois (to Martha): How many gas leaks do you know of in safe houses?

Pilot: What is it? A bird? A plane?

Bridgette (to Martha): Your son's destiny was set in motion long before their (Clark and DR. Swann) paths crossed.

Bridgette (to Martha): The only challenge to a father's will is a mother's love.

Lionel (Lex): You know, they dubbed Mussolini a savior...and look what happened to him.

Lex: Apparently I'm not ordinary.
Lionel: Of course not, you're my son.
Lex: God help me.

Lex (to Lionel): Shouldn't wound what you can't kill, Dad.

Clark (to Jonathan): The real hero is mom. If it wasn't for her, I'd still be Kal-El.

Clark (to Jonathan): Kal-El could fly. Clark Kent is still earthbound.

Lionel (to Lois): You bite your nails. Bad girl.

Lois (to Lionel): I want to look in the face the man responsible for my cousin's death.

Lionel (to Lois): Zoo hours are over Ms. Lane. Good day.

Lois (to Clark): Glad to see we've moved beyond the clothing-optional stage of our relationship.

Lois (to Clark): You should know. I don't pay much attention to curfew and I never make my bed.

Clark (to Lois): Lois! Chloe's still alive!

Chloe leaves a taped message in case of her death to Clark . . . but her cousin Lois Lane gets hold of it. Traveling into Smallville, a lightning strike drives her vehicle off the road and she ends up in a corn field where a naked Clark materializes. He doesn't know his name and seems out of it. In Egypt, workers discover a statue of Ra in a pyramid and Lex arrives to take it.

Lois takes Clark to the hospital while Lana is in Paris taking photos when she runs into a fellow American who turns out to be her boyfriend. Martha reads to a comatose Jonathan and refuses to pull the plug on him despite the fact he's brain-dead and their insurance is running out. Back in Smallville, Clark leaves despite Lois' best efforts, insisting he shouldn't be there. Martha spots him as he departs but he doesn't recognize her either. She convinces him to go with her by helping him with the "sign" he's looking for. In Egypt, a weakened Lex has everything in the pyramid buried before departing. When he gets back to the plane where it is revealed he has to have his blood purified every 24 hours or he dies from the poison he was given previously. When the plane hits turbulence Lex drops the statue and they find a crystal within. It glows when he touches it and in Smallville, Clark senses it, announces himself as Kal-El of Krypton, and flies off into the air.

In Paris, Lana and her boyfriend Jason Teague are kissing and then she does a rubbing from a church and uncovers a figure that unleashes a burst of light. Martha tries to get hold of Dr. Swann when Lois meets with her to talk with Clark - with Chloe's death, Lionel is going to go free. Clark closes on Lex's plane and enters it, grabbing the crystal and leaving before Lex can see him.

At the barn, Martha is confronted by Bridgette Crosby, Dr. Swann's "assistant." She convinces Martha to let her help but can't do much - the symbol burned into the cornfield three months earlier was the Kryptonian symbol for "Crusade." She advises Martha to face Clark and provides a chunk of "black kryptonite" to cure him. At the penitentiary, Lex visits Lionel and discuss the company's waning fortunes. Lionel denies any knowledge of the attack on the jet and Lex talks about how he is seeking for three ancient relics that will unleash a great treasure . . . which Lionel financed when he was free in an attempt to save his life. Lionel denies everything and Lex reveals how he survived the poison . . . which would kill an ordinary man.

Clark returns to the Indian cave and opens a doorway into a secret room. He places the crystal into a pedestal . . . which triggers some kind of vision in Lana in her apartment in Paris. She answers a loud knock on the door by Jason. She doesn't remember how she got to the apartment. Clark emerges from the chamber where Martha is waiting for him and touches him with the black kryptonite. Clark goes through a set of seizures and personality manifestations and seems to fight his Kryptonian Kal personality. Martha tosses Clark the black-k which he uses to defeat "Kal," and Jonathan wakes up in the hospital.

The Kents are reunited while Lana takes a shower and discovers a strange tattoo on her back. Lois pays Lionel a visit in jail and doesn't seem to believe he was responsible . . . but gets him thinking about who was, and what they may be planning. Lois visits Chloe's grave and vows to avenger her; Clark is also there and offers to help, as well as a place to stay. Clark x-rays Chloe's grave and sees that the coffin is empty - Chloe is still alive!
