<EM>Smallville</EM> Smallville

It's taken all season, but Clark Kent is just about done rounding up all the prisoners he accidentally let escape from the Phantom Zone last fall. In tonight's Smallville season finale (8 pm/ET on the CW) he goes after the final fugitive. "The last Zoner is definitely trickier than the others, and will lead us into Season 7," previews executive producer Al Gough. "This won't be the last we hear from the Phantom Zone."

It's not all bleak for Clarkie, though, as Lana (Kristin Kreuk) will be back on the market soon. Mrs. Luthor is going after Lex (Michael Rosenbaum) now that she knows he faked her pregnancy to manipulate her into marrying him. "She and Lex are way beyond marriage counseling," Gough says. "Now Lex is gonna find out what Lana's been up to. These two make Ike and Tina look like domestic bliss."

The action-packed hour will also finally reveal the Kryptonite-fueled ability that's been lying dormant in Clark's pal Chloe (Allison Mack). Gough won't say what her superpower is, but advises to keep an eye on Lois Lane (Erica Durance) in the episode. Lois has a "very important" role, he says, and "she is the key to Chloe's power manifesting."

And what would a Smallville season finale be without an explosive ending? Gough will neither confirm nor deny the rumor that a series star — Clark, Lana, Lex or Chloe — is going to die, and only offers up this tease: "Who says only one character can die in a finale?"
