Lex (Michael Rosenbaum), having just been arrested for Lana's (Kristin Kreuk) murder, is submerged under water in a patrol car, but is saved by a mysterious young woman. Lois (Erica Durance) manages to pull Chloe (Allison Mack) to safety but her cousin is pronounced dead at the hospital.
The same woman who saved Lex reappears at the Kent farm and is revealed to be Kara Kent (Laura Vandervoort) A.K.A. Supergirl, Clark's cousin from Krypton.
