Actor Jeffrey Dean Morgan is making a return to Supernatural to help celebrate the show's milestone of 300 episodes, 12 seasons since he was last seen on the series. John Winchester (Morgan), the father of Sam (played by actor Jared Padalecki) and Dean (played by actor Jensen Ackles) was killed back in season two, saving Dean's life in the process.

While Morgan's voice was heard in season three, he hasn't appeared on the series in all the years since, and now he is finally coming back, reports eonline.com. "We're incredibly excited to have Jeffrey back for this milestone episode, and think fans will love what we have planned for his character...and a few other surprise guest stars," said executive producer Andrew Dabb.
