Clark and Chloe had a fireside chat about Chloe being more trustworthy than Brainiac gave humans credit for
As events unfolded that forced Clark to accept his Kryptonian destiny and collect the Stones of Power, Clark and Chloe’s high school graduation was thrown into turmoil. Chloe discovered a weakened Clark in Lex’s vault and dragged him to safety. He and Chloe were transported to the Arctic where she was the first human to see the Fortress of Solitude.
College Years
There, Clark finally had to address that Chloe knew his secret. Chloe revealed she saw him catch a car «like it was a beach ball.» Clark admitted that he is from another planet, but Chloe was not appalled or frightened-she reacted with wonder and admiration. Chloe questioned Clark’s seemingly flippant reaction to suddenly being human, telling him she thought his destiny was greater than being a farmer in Kansas.
She helped him rescue Lana and the Kents from escaped patients from Belle Reve. When Clark’s powers were restored, he confided in Chloe the uncertainty and disappointment he felt. When Lana was infected with a vampire-like strain of rabies, she bit Chloe and Clark rushed Chloe to the hospital and found the cure for both girls.
While under the influence of silver kryptonite, Clark hallucinated that Chloe told his secret to Lionel, but after the effects went away, Chloe told him she would die before she betrayed him and they hugged. Chloe investigated Professor Fine which led her to the Fortress, where she helped Clark defeat Brainiac by removing green K from his chest.
During his rocky relationship with Lana Lang, Clark often put Chloe in an awkward position, asking for sex advice, whether Lana missed him after their breakup, and a variety of other relationship issues. Chloe told him each time that he should tell Lana the truth and was a bit surprised when Clark announced his engagement to Lana. After Clark reset the day to prevent Lana’s death, Chloe helped him to make sure it did not happen again.
When Martha was mugged, Chloe and Clark met the Angel of Vengeance. Chloe realized that Clark’s grief over the recent death of his father might make him do something he would regret. She strongly objected to his going after the thieves, but Clark didn’t listen and almost killed a man. He later confessed to Chloe that he should have listened.
Chloe followed Clark to the Fortress and almost died from the extreme cold, but Clark interrupted his training to take her to a hospital
Chloe seemingly tried to commit suicide, and Clark asked her if she wanted to talk about anything, but Chloe told him that she would never try to hurt herself. She began to see a ghost and was placed in restraints in preparation for transfer to the Belle Reve sanitarium. Clark broke her out of the hospital and because he believed her, he was able to help her prove she was being followed by a ghost. Clark encouraged her to visit her mother for the first time.
Clark got mad at Chloe for concealing the fact that Lana and Lex were dating, but he later apologized and congratulated her on her first front-page byline. They teamed up with Lex to find Martha and Lionel who were trapped by a madman seeking revenge on Lionel. As the events of Dark Thursday unfolded, Clark worked tirelessly to prevent the chaos, even saving Chloe’s life from a car flying through the window of her Daily Planet office. She convinced him to go out and stop Lex instead of taking her back to the farm, but before he went, she gave him a passionate goodbye kiss, «in case they never saw each other again,» and Clark appeared to reciprocate.
