She learned that her father, the one who was married to her mother and had died in the meteor shower, wasn't actually her biological father -- that she was actually the daughter of Henry Small, part of the line of Smallville's very own founding family. They worked for a while on a relationship, but Lana concluded that her presence in his life was too much of a strain on his marriage and stepped out quietly. Whitney returned home from the war, amnesiac, thinking that he and Lana were still together. He managed to begin to turn Lana against Clark before it came out that "Whitney" was in fact a meteor-infected student from season 1, Tina Greer, Lana's one-time friend who had become obsessed with her and wanted to be her. Tina died by accidentally impaling herself in the back alley behind the Talon. After the Tina incident, a group of guys wound up assaulting Lana at the Talon and, realizing that it wasn't her safe haven anymore, she went to Lex to ask him to train her in the art of self defense. Through her sophomore year she demonstrates herself as exceptionally capable thanks to his teachings.
Red kryptonite made an appearance a few times through her sophomore year, putting strain on her relationship with Clark, first because it led him to be the worst date ever when they finally went on a date together, also causing him to lay one on Chloe while he and Lana were supposed to be seeing one another. Later, it even caused him to leave town at the end of the year after he'd bailed on Lex Luthor's wedding to Helen. Lana tried to persuade him to stay, and Clark simply invited her with him. She declined, saying that Smallville was her home. Clark disappeared for three months, during which Lana helped the Kents heal and tried to help them find their son. She realizes that she loves Clark and when Chloe owns up that she's known where Clark is, Lana feels betrayed but immediately goes to get him in Metropolis. She couldn't have been more horrified by the Clark that she found, who was still toked up on red K and acting like a player as well as stealing and hurting people. Eventually she convinced him to return to Smallville, however, though their relationship appeared mostly irreparable.
Clark remained in Metropolis under the name Kal for three months. During that time, Chloe and Lana bonded and Lana came clean about her relationship with Clark. After three months when Lana decided she was going to go to Metropolis to find Clark, Chloe admitted she'd known where he was all along. Lana, enraged at Chloe, headed off to Metropolis to meet up with Clark. Clark refused to go back with her, and she refused to leave him again, so she went along with him to some club in Metropolis. He acted like a total douche and she tried to call Jonathan to tell him where Clark was -- Clark caught her and ran. She returned to Smallville and Jonathan went to fight Clark to get him back and off red K. When Clark returned to Smallville, Lana refused to be in a relationship with him but remained close friends with him in hope that he would open up to her, though Clark concluded that she could never love the parts of him that he kept hidden.
Lex starts going crazy and while Lana and Clark try to protect him, Lana winds up getting trampled by a horse and put in the hospital. As she recovers, she develops some bitterness towards Clark for defending Lex to the end and keeping him out of Belle Reve long enough for him to get her hurt. In rehab, she meets Adam Knight, who motivates her to take charge of her own life and buck up and get done with her therapy. He tells her his hard life story and she offers him the apartment above the Talon because he wants to stay in Smallville. She begins to suspect that he might be hiding a dangerous secret and Adam gets aggressive with her when she presses it. As a result, Lana goes to Lex and asks him to get rid of Adam by evicting him from the Talon, which is Lex's property. Adam winds up trying to shoot Lana, but Clark saves her (without her knowing) and Adam goes missing, presumed dead due to his terminal disorder that requires LuthorCorp's revival drug.
