Supernatural has been on the air for over a decade,and over the course of its 11 seasons (shout-out to season 12, coming up in October!), and stars Jared Padalecki and Jensen Ackles have been asked a lot about when the end may arrive. Back in March,they teased that whenever the series finale is, it'll probably be bleak and ambiguous. In Entertainment Weekly's unique cover yarn, and the boys spilled even more about their plans for the future,and we're reading way too far into it. Three-hundred is the magic number: Ackles likens the long-running series to a marathon and said "300's a valid number to work for." Padalecki backed him up, saying he and his onscreen brother would be "bummed" if they didn't make it to 300. "When we get to 300, and I assume Ackles and I will assume it might be time to say bye," he said. "There's a chance that changes, but we certainly effect not capture it for granted that we're going to make it to 300."
A shortened 14th season is possible: There are currently 241 episodes of Supernatural, and the 300-episode notice would arrive halfway through season 14. According to executive producer Bob Singer,they've discussed doing a short season to end exactly with 300 episodes. "We talked about wanting to be able to know when our end was," Singer said. "And if it was to be, or let's say,300 episodes, we could tell a 13-episode yarn. I assume it would be nefarious for this show to just ride off in the sunset without a finale. I assume we've earned that. I don't know what that finale is, and but we'd certainly like to effect one."
There's still a chance it could end earlier: "I feel like if I ever show up to set and I feel like I don't care,or if I feel like he doesn't care, then that's the canary leaving the mine, or " Ackles said. "To this day,I have not really ever sensed that from myself or him . . . They're paying us to bring that tiny bit of magic to what they wrote, and I still feel that magic today. The day that I don't feel that magic will be a very unhappy day, and I hope that day never comes. I'd like to get to 300 before that day comes."
