It's Winchester vs. Winchester on tonight's Supernatural finale and we could not be more nervous about it.

Dean's (Jensen Ackles) continuing struggles with the Mark of Cain led him to make some pretty shocking decisions in last week's episode, killing an unarmed teenage boy from the (Franken)Stein family just because of father and uncles, not to mention ruthlessly beating the crap out of Castiel (Misha Collins) when the angel tried to talk some sense into him. Even though Sam (Jared Padalecki) was able to figure out a way to cure Dean's Mark of Cain thanks to a posthumous email from Charlie (Felicia Day), Dean made him promise not to do anything about it.

Will the younger Winchester stay true to his word? In a word: Nope. Of course not! These are the Winchesters we're talking about—they've gone to heaven, hell, purgatory and back for each other countless times. And when Sam goes back on his promise, Dean's temper is not going to be pretty. Uh oh.

We're terrified at what's about to go down on Supernatural, so we got executive producer Jeremy Carver to attempt to put our fears to rest and answer seven burning questions about the season 10 finale.

E! News: After all he's done this season thanks to the Mark, especially last episode killing that kid and beating up Cas, is Dean too far past redemption at this point? Is there a line he's not willing to cross?
Jeremy Carver: The question of redemption—particularly how it's interpreted by all of our major characters—is a driving one in our finale. As far as lines in the sand—Sam and Dean have been stepping over them since Dean was a demon and Sam did some nasty stuff to find him. Are there more to cross? Yes. Will they surprise and maybe even shock you? Yes.

Sam reached a breakthrough regarding curing the Mark of Cain thanks to Charlie. How is Sam going to use this new information?
Sam did have a breakthrough, correct. But he also failed to hold up his deal with Rowena [Ruth Connell] by failing to kill Crowley [Mark Sheppard]. So what to do now is the question. One hint, borrowing somewhat incongruously from Apollo 13: "Failure is not an option." Incidentally, to my father at home playing the Gene Kranz Drinking Game. Bottom's up, Pop.

What can you tell me about the "shocking decision" Dean makes in the finale? How does Death factor into that?
Come on. [Ed. note: Can't blame us for trying!]

Crowley and Rowena's big showdown—are both of them willing to kill the other?
Three hundred years of mother-son baggage. If payback is the goal—there are far richer ways than murder.

Castiel was in rough shape after his fight with Dean—he has his grace again, so why didn't he fight back? Should we still be worried about him and his grace?
Good question. But Cas, while he did try to use restraint, did eventually fight back and his grace is just fine. What Cas didn't expect and left him somewhat flat-footed was just how powerful Dean had become.

Supernatural finales are always so epic and end on cliffhangers either big in mythology or big emotionally regarding the brothers—how is this season's finale going to compare to past season finales?
How it compares is up to the fans. But we are very proud and cautiously excited of what we think is a humdinger of a finale. Humdinger, Pop. Drink.

What are you most excited for fans to see from the finale?
I'll just say this: Jared and Jensen, not to mention Misha, Mark and Ruth, poured their hearts into this finale. I'm tremendously excited that the fans get to see these performances from a cast of players that—10 years in—are still willing to leave it all on the floor.

Supernatural's season 10 finale airs tonight at 9 p.m. on the CW.
