Zap2It got to talk to Jared about some of the changes in the story myth, which plays into tonight’s episode, “Trial and Error.”

…there are more significant developments as Sam and Dean argue over who will complete a set of tests that will lead to information about closing the gates of hell.

Spoiler alert: Sam wins that particular battle.

Apparently, there will be blood involved, as if that’s a shocker, but at least it won’t be a bloody nose, which according to what he says in the video, is quite annoying.  

“It’s like a consumption,” Padalecki says. “Like he’s having Tuberculosis type [symptoms], hacking up blood and kind of trying to hide it from his brother. Nasty, but kind of cool.”

He goes on to explain why the trials that will cause his character to hack up blood is so important. 

“There is no finish line, but it is a finish line,” he says. “If they accomplish these trials, they can shut the gates of hell forever and keep demons out of earth, so they really want to do it. It’s not easy, and it seems like something that could kill either one or both of the boys, but it’s worth the trade-off in their opinion.”

Things will definitely get ugly for Sam as the trials take a physical toll on him — which is convenient, since Padalecki isn’t exactly in fighting shape himself after taking a fall on the ski slopes over his holiday vacation. He’s still nursing a broken rib.

“I’m concerned, as an actor, of what these trials are going to do to my character,” Padalecki admits. “It’s going to get pretty taxing … He’s starting to lose some of his physical prowess as well. Today we’re doing a fight where Sam is really getting beat down because he’s kind of lost a step … so I’m concerned about how beat down Sam’s going to get.”

He discusses more about his character, the dialogue involved, and he even mentions a bit about the infamous tweet below:

That having been said, I’d be oh-so-excited if Supernatural and/or Jensen and/or I won. And, when I’m excited, my clothes fall off. So vote!
