Lana enrolls at Metropolis University at the last minute and is forced to join a sorority in order to get housing at such a late date. However, her new sorority sisters offer her more than a place to live after they turn her into a vampire and instruct her to kill Clark. Meanwhile, Chloe applies for an internship at The Daily Planet, but the newspaper's formidable editor, Pauline Kahn (CARRIE FISHER - "Star Wars"), may be more then she can handle.

In flashbacks, Lex and Oliver (recurring guest star JUSTIN HARTLEY) are teenagers attending the same prep school, where Oliver and his friends bully Lex and his buddy Duncan (BRYCE HODGSON). In order to gain the others' acceptance, Lex beats up Duncan, inadvertently sending him staggering into the path of a speeding car, which kills Duncan. In the present day, Lex and Oliver--whose secret identity is the Green Arrow--return to the school for a reunion and are startled when Oliver's old pals start getting killed in violent and mysterious accidents that somehow point to Duncan. Meanwhile, when Clark sees satellite photos showing that four other craters were created the day he escaped from the Phantom Zone, he realizes that others may have followed him.

Olivia pressures Paul to take a chance on love; Olivia's relationship with Jack continues to be in question.
