"Supernatural" season 10 spoilers revolve around the brotherly love between Dean and Sam Winchester as cast Jared Padalecki shared Father's Day photo of his two sons.

Jared Padalecki, who plays Sam Winchester, revealed "Supernatural" season 10 spoilers to TVLine when he said that the relationship between the brothers won't ever be the same after their reconciliation in the season 9 finale.

"You see in the finale a lot of what makes Sam and Dean 'Sam and Dean,'" he said. "There's a lot of that brotherly love that the show is based on. So hopefully next season we bounce off of that."

It's not clear, however, if he's writing about the premiere episode.

Misha Collins, who plays the role of Castiel, hinted that the finale episode provided a platform for writers to introduce new storylines next season.

"The cliffhanger at the end of season 9 is great and it really sets up some rich stuff," he told TV Fanatic.

In season 9 finale, the Mark of Cain turned Dean Winchester (Jensen Ackles) into a demon instead of killing him. The episode "Do You Believe in Miracles?" ended with the camera showing Dean's black eyes.

Writer Adam Glass also posted his own version of "Supernatural" season 10 spoilers when he wrote on Twitter: "Ok #Supernatural rough board 4 my episode goes up today. I've got some yummy boys stuff to play and a week to get it right b4 pitching it."

Meanwhile, Jared Padalecki is taking advantage of the break from shooting "Supernatural" to spend quality time with his family.

On Father's Day, he posted a photo of his two sons, Shepherd and Thomas Colton, playing inside a basket. He also captioned the photo: "Happy Fathers Day to all u out there! Wadda fun (and exhausting!) club we get to be in, huh? #bestjobever @HipDaddy1"
