Supernatural's Jared Padelecki hints that Sam will dance with the devil

Jared Padalecki, who plays Sam Winchester on The CW's Supernatural, said that he's sure his demon-hunter character will have to deal with the consequences of using his mystical powers as the current season wraps.

"By the end of the season, I'm sure they're going to do something big, and ... —I'm speaking as an audience member—but I'm sure we're going to see Sam go dark side or get very, very close to going to [the] dark side," Padalecki said in a group interview on Saturday in Beverly Hills, Calif., where he was promoting his upcoming movie, Friday the 13th.

In the current fourth season, it's been revealed that Sam has developed the ability send demons back to hell with a wave of his hand. He's also taken up with Ruby (Genevieve Cortese), a demon in human form. This despite warnings from his brother, Dean (Jensen Ackles), that there will be hell to pay if he keeps it up. Padalecki said the show has completed 17 of the season's 22 episodes.

Padalecki admits that series creator Eric Kripke keeps him in the dark about upcoming plot developments. "Sam is definitely getting more into his supernatural abilities, whatever they may ... be," he says, then adds: "Our writer, Kripke, kind of doesn't let us in on a whole lot. And I'd rather not know, you know? Because I don't want to worry about it."

A lot depends on whether Supernatural gets picked up for a fifth season, Padalecki says. "I hate it, because we're on the sort of brink where it's like, 'Well, are we going to come back? Do we know if we're going to come back for another year, or should we wrap it up?' ... That's where TV is just a pain in the ass, because you're like, 'Just tell me how long I have so I know how to tell a story.' As opposed to 'Let's keep asking questions. Let's keep answering them with more questions.' I hate it. I hate it. It's really frustrating. But I'm sure something'll happen." Supernatural airs Thursdays at 9 p.m. ET/PT.
