“If we don’t make it to 300, I think Ackles and I will both be truly bummed,” Padalecki says. “When we get to 300, I think Ackles and I will think it might be time to say bye. There’s a chance that changes, but we certainly do not take it for granted that we’re going to make it to 300.”
At this moment, all they know is that they still love these characters. “I feel I’ve learned a lot from my friend Sam. I’ve learned a lot from my friend Dean. I want to tell that story as well as possible as long as possible, but I don’t want it to get too long in the tooth,” Padalecki says.
Ackles chimes in: “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. To this day, I have not really ever sensed that from myself or him… They’re paying us to bring that little 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 sad day, and I hope that day never comes. I’d like to get to 300 before that day comes.”
For now, there’s still plenty of gas left in the Impala’s tanks. Speaking of which, the only thing that’s certain about Supernatural’s end is Baby’s fate. “He gets Baby,” Padalecki says of Ackles. “I get Baby Two.”
Ackles makes one correction: “No, you’ll get Three. Two is stunt. It’s beat to s—.”
