Smallville :

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, the house leader Buffy Sanders and 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. Lex provides Clark with an antidote for Lana, after Luthorcorp is revealed to be connected to the vampires.

Meanwhile, Chloe applies for an internship at The Daily Planet, but the newspaper's formidable editor, Pauline Kahn (guest star Carrie Fisher) may be more then she can handle.
