“Bizarro” Offical Description

The CW has released the official descripton for the season premiere.

CLARK FACES BIZARRO, HIS TOUGHEST ENEMY YET AND SUPERGIRL COMES TO SMALLVILLE —

Clark (Tom Welling) 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 (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) AKA Supergirl, Clark’s cousin from Krypton. Aaron Ashmore
and John Glover also star. Michael Rohl directed the premiere written by Brian
Peterson & Kelly Souders (#3T6301).

Half of it sounds like the premiere and the other half sounds like the next episode. If there’s one thing I’ve learned over the years of watching the show is to not entirely believe a description, cause there not always accurate to what actually happens in an episode.
