A girl named Alicia becomes obsessed with Clark. Lana asks Lex for help in getting rid of Adam and the reason Adam is in Smallville is revealed!

What's up with Clark: While on a field trip Clark and fellow student Alicia get on an elevator together. When the doors shut, the cable breaks and it begins plummeting 35 floors. Clark has no choice but to fry the security camera then use his super strength to stop the elevator. Alicia is noticeably shocked, and as the security teams begin to open the door, Clark asks her not to tell anyone. Alicia grabs Clark and teleports him to an empty floor. Now Clark's the one surprised and Alicia says now they both know each other's secrets. The next day at school, Clark asks Alicia about her powers. She says she's had them since the meteor shower and that she's relieved she can finally share her secret with someone. Later, Clark and Alicia deicide to meet up after school for a movie. After the movie they look at stars at the loft and bond over their powers. When Clark drops her off they move in for a kiss, but Clark pulls away at the last minute and heads home. As he's sleeping that night, Alicia teleports into his bed and the two kiss passionately. As they're kissing Jonathan walks into the room. Clark tells his parents about the elevator incident and that Alicia doesn't know all about Clark's powers and how to stop them. Alicia teleports into a near by closet and listens to Clark say he thinks he's finally found someone he can have a relationship with.

What's up with Lana: Lana sneaks into Adam's room and finds a journal he's been keeping about her and Clark. Adam finds her and demands she give it back. She says no and that she wants him to leave, but Adam tells her he's not going anywhere. Lana goes to Lex for help in getting Adam out of her life. Lex tells her not to worry.

How it ends: Alicia puts pictures of herself all over Clark's locker. She tells people she's his girlfriend and tries to kiss Clark in the hall. He freaks out and tells her things are going to fast, to which she replies "people like us don't have boundaries." Clark continues to worry as Alicia continues to become more and more obsessive and controlling. He goes to see her family and her parents say that he should be careful because the last time a boyfriend tried to leave her it turned out badly. As Clark leaves, Alicia teleports in and tells her father he shouldn't have warned Clark. Clark finds out Alicia hospitalized her father and tells her she should turn herself in. She refuses and tells Clark if he wants his family safe and secret kept, he'll keep his mouth shut and be her boyfriend.

Clark enlists Chloe's help and the two set a trap for Alicia. She thinks Clark's in trouble and heads off to find him. Clark tricks her and gets her in a room that's been covered in lead paint. Alicia tells him that she can't teleport out, but she can walk out. And with that, she uncovers a piece of kryptonite, she overhead Clark's parents saying it was his weakness. As Clark falls to the floor she tells him that once she gets Lana out of the way, he'll come to his senses. Alicia hunts down Lana and tells her that Clark is still in love with her and that she must get her out of the way. As she's chasing Lana, Clark kicks over a bucket of lead paint onto the piece of kryptonite... neutralizing its power and allowing Clark to come to Lana's aid. Clark covers Alicia in lead paint, stopping her from teleporting and saving Lana's life.

The next day Lana stops by the farm to thank Clark and confront him about still being in love with her. Clark says it's not true and a disappointed Lana walks away. When Lana returns to the Talon she finds that Adam is gone, but Lex tells her he had nothing to do with it and that no one can find any traces of him... Adam is seen strapped to a chair with Lionel Luthor hovering around him. He tells Adam he's failed. That he sent him to Smallville to become friends with Lana and learn all he could from her about Clark. Dr. Tang comes in with the serum Adam needs to live, but Lionel tells her Adam's purpose is over now that he's alienated Lana and Adam is left in the room to die.
