Clark confronts Bizarro, the last wraith from the Phantom Zone, and the ensuing fight causes the dam to break and a torrent of water rushes towards the land. Lex, having just been arrested for Lana's murder, is submerged under water in a patrol car, but is saved by a mysterious young woman.

Lois manages to pull Chloe 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 A.K.A. Supergirl, Clark's cousin from Krypton.
