James L. Conway, co-executive producer and director of The WB's witch series Charmed, offered SCI FI Wire a few juicy details about the series' upcoming two-hour sixth-season finale, which brings the conflict between Gideon and Wyatt to a head. "Gideon [Gildart Jackson] has been trying to do something with Wyatt," Piper's (Holly Marie Combs) child, Conway said in an interview during a break in filming on the show's set in Canoga Park, Calif. "He's afraid that Wyatt is too powerful."
Conway said that Gideon makes use of a mirror-like device to open a window to a parallel dimension, an evil version of our world. "In the parallel dimension, there's an evil version of the Charmed Ones [Combs, Alyssa Milano and Rose McGowan]. There's an evil version of him, and the world is all evil," Conway said while lining up shots for a confrontation between Gideon and Leo (Brian Krause). "Our girls are inadvertently sent over there, and they have to escape. The only way they can escape that world is by doing a lot of good."
Without divulging too many secrets of the epic conclusion, Conway said that Gideon's shenanigans cause numerous troubles for the sisters once they find their way back to the normal world. "When they accomplish that, when they come back to this world, they upset the balance," Conway said. "Now this world is too good, like Pleasantville, and everyone has big smiles on their faces. But if you make a mistake, you get your arm chopped off. You steal something, your arm gets chopped off. If you don't leave when somebody tells you, your legs get chopped off, and everybody happily accepts those kinds of punishments. So now the world is really screwed up," he said with a smile.
Conway added that Wyatt's and Gideon's longstanding conflict finally comes to head, though he declined to say exactly how. "In an earlier episode, he did capture Wyatt and try to kill him, and the girls found out about it, and they rescued him," he said. "But now Gideon's plotting again. This time, he does again grab Wyatt and takes him down to the underworld. But Wyatt escapes and orbs out during the show, so they're trying to find him." The Charmed finale airs in a two-hour block starting at 8 p.m. ET/PT on May 16.
