Winchesters Gone Wild! | Jensen Ackles got his cowboy on when Supernatural transported Dean and Sam to the Old West for an upcoming episode. “The guys find a formula to battle Eve, the mother of all monsters, but the problem is the only record of this formula ever existing happened over a 100 years ago,” Ackles previews. “So they call upon their angel friends to give them a time-travel experience.” The excursion fit like a glove, says Ackles, who like Dean is wild about Westerns. “I sent a picture to my father [from this episode], and he wrote back, ‘You’ve been rehearsing this scene since you were six.’” Hopefully he rehearsed it well, because Supernatural pulled out all the stops. “I get to have, like, a high noon shootout, we get to see a hanging…,” says Ackles. “We packed a lot into a 42-minute episode. It’s really good.”
