Supernatural Season 10 Spoilers: Sam and Dean's Relationship Tested in Coming Episodes

For the early part of Season 10 of Supernatural, Sam risked life and limb to rescue his brother Dean, who had been turned into a demon, and cure him. The brothers have been through almost everything in 200 episodes, but their relationship will once again go through a perilous test in the coming episodes.

The "Spoiler Chat" column at E! Online has some information about the trials ahead for the Winchesters. "Executive producer Jeremy Carver told us that's going to be a huge part of the rest of the season. 'The [brothers'] newfound rediscovery of [their] bond is really put to the test in the coming episodes,' he says. 'Their troubles are not over yet for either of them. Dean's not quite out of the woods yet regarding the Mark of Cain and Sam is not quite out of the woods as to what that means to him as well.'"

In other news, Supernatural airs its 200^th episode tonight, and stars Jensen Ackles and Jared Padalecki told E! Online that they were not thrilled with the idea at first.

"I didn't have a positive reaction," Ackles said. "The first time in I think 200 scripts I went and sat down in the showrunner's office and said, 'What in God's name are you doing?! Why? I need to understand why this is happening.'"

But Carver convinced the star of the merits of the episode.

"He gave very eloquent answers and did a great job of explaining why we were doing what we were doing," Ackles said. "I guess I had been aware of this 'fan fiction' for a while and I felt like maybe if I ignored it, it would eventually go away. When I read it in the script that is what I do for a living and is my work-I'm very protective of these characters and the story and I think we have a right to be-I wasn't angry. I just wanted to understand why and what was the message we were ultimately sending with this script and story. By the end of it, I felt good and it gave me all the confidence I needed. It was better than I could have ever hoped."

"I never should have even sat down in that office, so Jeremy, I'm sorry," he concluded.

Padalecki's reaction contained a bit more fear. "'Please don't make us sing,'" he said with a laugh. "We've been in a situation like this more than actors on other shows where they tell us to break the fourth wall. We're always thrilled. Our approach to this, is as long as we can remain true to Sam and Dean in the situation, which obviously makes for a lot of comic relief, then it's kind of daunting."
