Lucy Lane is the younger sister of Lois Lane and a recurring character in the WB/CW Television series Smallville.
She appeared as the secondary antagonist in the Season Four episode "Lucy".
After her mother died, Lucy was shipped off to boarding school in Switzerland by her father General Sam Lane while her sister, Lois, stayed with him as he moved between military bases. While overseas, Lucy met a Swiss criminal loan shark named Marcus Becker and had borrowed $50,000 from him.
Lucy went skiing down a mountain when she was chased by Marcus and an associate. Having ran into trouble due to her financial situation, Lucy came to Smallville under the pretense of wanting to see her sister. Lucy arrived at the Kent Farm and was welcomed to stay for a few days. She got along with Clark since she was constantly flirting with him.
While at the Talon, Clark noticed Marcus staring intently at Lucy. Clark asked Lucy who he is, but when she turns to see, he's gone. Later that night, Lucy slipped out of the house and went back to the Talon to steal money from the cash register but was caught by Clark who followed her there.
When he questions her, she confesses that she got in with the wrong crowd, ran up her credit cards, and owes a loan shark in Europe fifty thousand dollars. Secretly, Lucy conspired with Becker to extort money from Lex Luthor. Clark and Chloe investigated and found the loan shark's identity and reported it to Lois.
Lois and Clark went to the Luthor Mansion where Lucy was demonstrating her violin skills for Lex. Lucy was angry at Clark for telling and insists that she could handle the situation herself. She and Lois argue about Lucy's actions until Lex defuses the situation and gets between the sisters.
Clark explains the truth and Lex agrees to help Lucy with the money, but only because Marcus Becker is one of Lex's old business adversaries.
Lucy insisted that she handled the money alone, but Lex accompanied her and Lois to an abandoned warehouse. But while exchanging the money, Becker pistol-whipped Lex and kidnapped Lois and Lucy as well, holding them all hostage in the back of an 18-wheeler.
However, Lois and Clark realized at the same time that Lucy was using them all.
Unknown to everyone, Clark intercepted the truck and was able to use his powers to incapacitate and apprehend Becker. Lex attempts to have Lucy turned over to authorities, but she escapes in his car. In the confusion, Lucy got away with Lex's money and went into hiding.
