The moment that Smallville fans have been waiting for seven years is about to arrive, when the show returns with new episodes in April. Brian Peterson, executive producer of the show, told SCI FI Wire that this episode shows where Lex truly goes bad.

"I would say if you are going to watch one episode of Smallville, you need to watch Descent", Peterson said. "It is pivotal. It is up there with Clark [Tom Welling] opening the Fortress of Solitude. It's right up there."

Kelly Souders, co-executive producer, added "Lex has had a lot of challenges in his life, and he's sort of gone and sat on that fence all these years. This is the episode he leaps off of it."

Before that moment, fans can look forward to the March 27 episode Veritas, where Kara teaches Clark how to fly, to help Clark prepare to battle Braniac.

Smallville airs Thursday nights on the CW. The drama about the early days of Clark Kent stars Tom Welling, Michael Rosenbaum, Kristen Kreuk, John Glover, Erica Durance, Allison Mack, Aaron Ashmore and Laura Vandervoot.
