"It's my favorite finale we've ever done."
Woah, that's big praise consideringSupernatural has had its fair share of epic finales. Eight previous ones, to be exact, so we're pretty sure Jared Padalecki wasn't exaggerating when he gushed about the CW hit's finale, "Do You Believe in Miracles?," airing tonight.
"True to Supernatural form, we go to the extreme," he told us on the red carpet at the CW's Upfront presentation in NYC. "I mean we're 195 episodes in, we have to do something kind of big time. So we do. There will be a big audience reaction."
And Jensen Ackles is backing up his on-screen bro, telling us that even he was surprised by what goes down in the finale. "I know what my reaction was when I got to the end of the page and my mouth was open," he said. "I will say that this cliffhanger surprised me more than most."
So just how dark will Dean (Ackles) go, thanks to the Mark of Cain, which has turned him into a bit of a killing addict? "I will say Dean...he will get darker than we have seen him," Jensen ominously teased.
However, he did have a bit of good news to share with fans: a possible make-up between Sam and Dean, after a rocky season. (And that's putting it gently.) "I will tease the fact that yes, there is a bit of a resolution there and a bit of a regrouping so to speak."
But before you start celebrating, Jensen was quick to add, "But it doesn't last long."
Of course, fans can breathe a sigh of relief going into tonight's finale knowing that Misha Collins is set to return as a series regular for Season 10, meaning more Castiel, which is always a good thing, right? Well, that depends on who you ask...
"We've been trying to get it into our contract that he's not allowed on set, but Warner Bros. isn't going for it," Jensen joked. "So it just means that our crew is going to increase in hazard pay with the pranks that Jared and I will be pulling on him. Everybody's going to have to wear safety helmets and goggles."
So will they be topping their infamous pie prank, which they pulled when Misha made his directorial debut earlier this season? "That was child's play. We're going to reserve a room for him at the ER," Jensen warned. "Jared and I have found out early on that we work much better as allies."
Sounds like they're brothers both on and off-screen, and Jared told us he's actually learned a lot from Sam and Dean's relationship on the show, which he hopes to pass on to his two young sons, Thomas, 2, and Shepherd, 5 months.
"What I've learned is that in my opinion, and the littlest one is five months, so he's too young to really grasp it, but you got a teammate," he told us. "Be happy, you're teammates...you have a best friend for life!"
