Clark (Tom Welling) must stop a kryptonite-infected man (guest star Reynaldo Rosales) who seeks to relieve the suffering of the elderly and sick by turning them into ashes - and Whitney's (Eric Johnson) ailing father may be his next victim. Meanwhile, Lex (Michael Rosenbaum) is furious after his father sends someone to look into LuthorCorp's financial records and this man reveals Lex's secret investigation into Clark and his family.
Kristin Kreuk, Allison Mack, Sam Jones III and Annette O'Toole also star. Terrence O'Hara directed the episode written by Cameron Litvack.

Tyler takes a fall out a hospital window during a struggle while trying to kill his suffering mother at her request. He apparently dies, but a kryptonite wrist band imbeds itself in his wrist and resurrects him, with a touch that turns people to ash. Tyler comes to Smallville and begins his euthanasia spree, but is spotted by Martha. Clark, who is immune to his power, intervenes and Tyler escapes. On the lam, Tyler targets Whitney's father, who is in the hospital with another heart attack. Clark reveals that Tyler's mother is alive, and Tyler uses his powers on himself when he realizes he based everything he's done on a mistake. Meanwhile, Lionel Luthor sends one of his lackeys, Dominic, to check on Lex, and the guy finds out about Lex's investigations into the Kent family. Jonathan isn't happy when he finds out, and Lex eventually drugs Dominic and returns him to his father, postage due.

Lex: In his own way he's just trying to give you something my father never gave me.
Clark: What's that?
Lex: Limitations. All my father ever told me was "don't get caught" and "don't cause a scandal". That's not love, it's public relations. You have no idea how lucky you are. When my father dies, kings will come to his funeral but when yours does, his friends will come.

Clark: You know this is a crime scene.
Chloe: So?

Jonathan: He's a good kid, Lex, I don't want that to change.
Lex: Neither do I. [pause] You know, from the day I first met Clark, all you've ever seen is the name "Luthor".
Jonathan: Well so far you haven't given me a reason to see anything else.

Lex: No, I just want you to understand that if I'm guilty of anything regarding your family, it's envy.

Clark: You don't have to look so happy about it.
Chloe: I'm not happy. I'm intrigued.
Pete: Which means you're still going to look into it.
Chloe: Am I that transparent?
Pete and Clark: Yes.

Lex: You want to ask an accounting question, dad? Call me. And the next time one of your drones bothers the Kents, he'll be lucky to ride home with the spare.
Lionel: Lex...well done.

Lex: It bothers you, doesn't it. That I'm not dependent on you anymore. I've made friends in Smallville, people I can trust.
Lionel: Don't be ridiculous, Lex, I'm happy that you're doing well.
Lex: No you're not. You're afraid I won't need you anymore.
Mr. Luthor: You'll always be my son. And you will always need me, Lex.

Tyler: It's a miracle.
Clark: It's life. As long as we have that, there's still hope.

Lex: You know in ancient Persia, the kings would kill a messenger who brought them news they didn't like. In modern times a sword in the chest might seem a little extreme. Something more subtle would be in order. Enjoying your drink?

Lex: Let's be frank, Dominic. My father sent you here to spy on me because he's afraid of how well I'm doing. This was my last chance to prove myself and he just assumed I'd fail. Now he has to revise his definition of me. I'm not just his screw-up son anymore. Now I'm competition. And my father only knows one way of dealing with competition.

Martha: I'm not going to play referee, you two need to work this out.
Clark: We will. First we'll have a week of uncomfortable silence and then we'll start talking about something trivial. And then we'll move on.

Lex: Do you know what my father gave me for my tenth birthday? A copy of The Will to Power. "Behold the Superman - man is something to be overcome." Sun Tzu, Machiavelli, Nietzsche, they were the voices that nurtured me after my mother died. My father made every question a quiz, every choice a test. Second best was for losers, compassion for the weak, trust no one. Those were the lessons I grew up with.
Dominic: I'll remember that if I'm ever interviewed by the Biography Channel.
Lex: All I'm saying, Dominic, is try to remember who I was raised by. I try to deny it, but I'm still my father's son. Tread carefully.

Clark: Besides, I know how we can catch more fish this year.
Jonathan: More lures?
Clark: X-ray vision.

Tyler Randall visits his mother in hospital. He is wearing a bracelet with a piece of meteor rock. She asks him to help her die. At first, he refuses, but finally agrees, and takes a pillow and begins suffocating her. A nurse walks in on him, and security stops him. They fight, and Tyler falls out of the window and dies.

At the morgue, the coroner begins the autopsy. He sees the bracelet on Tyler's wrist, and sees that, because of the fall, the rock has embedded itself into Tyler's skin. The coroner removes the bracelet and the rock. He goes to begin the autopsy, but Tyler wakes up, and grabs the coroner's arm. The coroner's whole body immediately turns to ash and crumbles.

She tells him she likes white roses, and he promises to bring her one the following day. Clark notices that Tyler is wearing gloves while caring for the patients (direct contact would turn them to ash).

Lana Lang is worried for Whitney Fordman because his father just had another heart attack, and Whitney is too upset to visit his father in the hospital. Tyler returns to the old lady that evening, and offers her a white rose. He then tells her he can help her stop the pain, and she agrees. He touches her and she turns to ash.

Later, she finds an article on the coroner's death, and relate both deaths. They visit the old lady's room, and Clark finds the white rose and Clark begins suspecting Tyler.

The following day, Tyler goes to help Martha with her vegetable delivery, but forgets to wear his gloves. Her basket turns to ash. She is terrified, and calls for help. Hank, who works at the home comes to help her and fights with Tyler. Hank gets turned to ash. As Tyler reaches for Martha, Clark saves her, but Tyler runs away.

Lana and Whitney go visit Lana's parents' graves, and Whitney apologizes for his visiting the graves for the first time. He explains to Lana how painful it is to watch his father suffer. She understands and encourages him to go to the hospital. She spends a little more time at her parents' graves, and bumps into Tyler, who heard Whitney's problem. Tyler explains to Lana that he wants to help Whitney's father. Lana gets worried and runs to meet Clark and Chloe. Chloe has just found out that Tyler's mother actually survived, her health improved and she is back home in Smallville. After hearing Lana's story, Clark runs to the hospital.

Tyler finds Whitney in his father's room, and encourages Whitney to let him help his father. Whitney refuses, and Tyler knocks him out. He then removes his gloves, and is about to turn Mr. Fordman to ash, when Clark walks in and confronts him. He tells Tyler that his mother is still alive and resting, and then go and visit her. Tyler begins to feel guilty for the people he killed, explaining that he thought he was brought back to life to relieve the suffering of others, but it was his pain all along. He can't take the pain, joins his hands together, and turns himself to ash and crumbles.
