Smallville :

Another outcast in the town of Smallville, Chloe has always been secretly in love with Clark, but often lets her journalistic truth searching get in the way of their friendship. Chloe started her reporting career as editor of the school newspaper and immediately displayed her highly inquisitive nature, especially when it comes to Mr. Kent. Her feelings for Clark are sadly not reciprocated and when she witnesses him kissing Lana, she agrees to use for sleuthing ways to dig up information on Clark for Lionel Luthor in exchange for a job at the Daily Planet.

When Clark and Chloe patch things up, Lionel has her fired from the newspaper. She decides to help Lex have Lionel arrested for the murder, again utilising her reporting skills. Though in protection from a vengeful Lionel, Chloe’s safe house blows up and its presumed she is dead. Her cousin Lois Lane comes to town to investigate the accident. Clark and Lois team-up and discover the truth and find Chloe alive. She unearths Clark’s secret when his girlfriend of the time, Alicia, hopes that Chloe will write a story exposing him but she decides that Clark must have kept his secret for a reason and ignores her.

Now Chloe knows the secret of Clark Kent, but is always disappointed that he never chose to tell her himself. He eventually tells her more of his story and reveals to her that he was not a infected by the meteor rocks, but he’s an alien who was sent to Earth as a baby. Chloe eventually returns to the Daily Planet, though in a lowly position at first, and also discovers she has powers of her own.

Chloe is fired from the newspaper once more when Lex discovers she has been keeping information from him. She decides to spend her time running Lana's Isis Foundation, a free clinic for individuals, like herself, who have been infected by meteor rocks. Just as her life seems to be settled, as regular boyfriend Jimmy Olsen proposes marriage, Chloe is arrested and detained and soon discovers she has additional super powers.
