|Occupation||Student (Smallville High School)|
|Played By||Stephanie Nudd|
On her last day at Smallville High, she was captured by Brendan Nash, a classmate who had the ability to turn people into wax statues. He had forced his father to recreate the interior of the school in an abandoned factory and made his kidnapped classmates pretend to be in school forever. She was placed in the faux school along with Chloe Sullivan, Lana Lang, Wendell Johnson, and Haley Timmonds.
When Chloe found herself in the school, she encountered Delia walking down a hallway with another girl. Delia advised Chloe to "play along" because Brendan was watching them. Clark realized that along with the others, Delia never picked up her cap and gown for graduation and he and Lois were able to help Chloe, Lana, and Delia escape from Brendan's delusion unharmed.
