It's been a good long while since we've heard anything from 'Supernatural' season 10, but with Jensen Ackles and Jared Padalecki on their way to Comic-Con 2014 next week, both boys and CW producers took a pit stop at the TCA press tour to talk future spinoff potential, Dean's demon days ahead, and when 'Supernatural' might finally hunt its last season.

“We’ll see demons and angels, ghosts and werewolves, and demon Dean,” showrunner Jeremy Carver teased of season 10 at the TCA press tour panel. “We’ll be staying with demon Dean for more than one episode — you’ll probably be seeing a different side of demon Dean than you might expect, which we’re all pretty excited about.”

In addition to a 200th episode titled "Fan Fiction" and questions of Castiel's diminishing grace and imminent mortality, the 10th season of the long-running CW series will introduce a new character as interested in Dean’s season 9 finale transformation as Sam and Crowley are. That certainly jives with the recently-released CW synopsis for the season, which reads thusly:

Season 10 begins with Sam’s frantic search for his missing brother, who is gone without a trace. The road to recovering the wayward Dean takes Sam down dark paths, with consequences that will shake the boys to their core. Meanwhile, Castiel has to pick up the pieces in the aftermath of Metatron's campaign. With his grace failing and rogue angels still on the loose, Cas will face the ticking clock of his own mortality as all-new threats emerge to once again push all of our heroes to their limits.

Naturally, conversation turned to talk of another potential spinoff after the failure of 'Bloodlines,' with CW president Mark Pedowitz confirming that they'd craft another attempt if the right material came to them, and blossomed creatively moreso than the first attempt. And where we might have thought continued interest in a spinoff to represent an imminent end to the series proper, both Ackles and Padalecki expressed their contentment keeping with the series for as long as the quality of writing kept its current levels.

“If the show quality diminishes, if it ever reaches a spot where we get a phone call [from Carver]… ‘we feel we’ve said what needs to be said…’ [that's fine],” Padalecki offered. “I think we know the show enough and know our characters to know. If there’s an end coming, I think we’ll all see it.” Carver had his own insight to offer on series creator Eric Kripke's original vision for the show's end after season 5, and how it might influence a potential endgame for 'Supernatural''s future:

I know that Eric Kripke always had an ending in mind which he hasn’t yet shared with me, and I have an image and the like, but I always want to keep room for happy accidents as well. The show is continuing on beyond any of our wildest dreams, so I don’t think we want to limit ourselves. Just because I have the perfect image in my head, doesn’t mean one of these guys couldn’t come up with something okay. I think we have images in our heads but our minds are wild.

We'll learn more from the Comic-Con panel next week, but in the meantime, what do you think? Does season 10 sound like it will keep 'Supernatural''s quality building, or should the CW series look to rest in peace before too long? Tell us what you want to see from the Winchester brothers when 'Supernatural' returns for season 10 this fall!
