Jared Padalecki doesn't appear to be in a super mood that Jensen Ackles will be carrying on the Supernatural franchise without him. The Gilmore Girls alum took to Twitter to share his apparent surprise that Jensen, his co-star for 15 seasons on The CW's beloved drama, is developing a prequel series that he's set to narrate as his character Dean Winchester, in addition to serving as a producer. Hours after Jensen posted a news article about the new project, titled The Winchesters, Jared quote-tweeted him and claimed to have had no idea the spinoff is in the works. "Dude," wrote the actor, "Happy for you. Wish I heard about this some way other than Twitter. I'm excited to watch, but bummed that Sam Winchester had no involvement whatsoever." Fans were understandably confused by the message, as it seems hard to believe that Jared wouldn't have been looped in. After all, what many fans loved about the original Supernatural series was the chemistry between the two leads. Jensen has yet to respond publicly to Jared's message.
