Related : "Supernatural" Finale Goes to the Extreme

"It's my favorite finale we've ever done."

Woah, that's big praise considering Supernatural 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."
