Supernatural's 'Emotional' 300th Episode Promises Time Travel, Tears

Supernatural is about to cross another major milestone. This week, the enduring series will mark its 300th episode that will bring Jeffrey Dean Morgan's John Winchester back to the series for the first time since Season 2. Speaking to CBR on the red carpet for the event, Castiel actor Misha Collins offered a taste of what's to come in the landmark episode.

"Everyone is gonna die," Collins joked. On a more serious note, he teased, "We're going to be reunited with fan- and character-favorites. There will probably be tears, and there will be a little bit of time travel."

Asked to tease the episode, executive producer Brad Buckner said, "Just that it's a bit of a surprise. It is a departure, because I think our landmark episodes have been kind of wacky, very strange, meta episodes. So I think one of the reasons the show has lasted is that, rather than keep trotting out the same formula and try to top ourselves, rather than do that same thing again with the 300th, it takes a real different approach and there's some surprises."

"I think it's surprisingly emotional. I think people aren't going to be ready for that. So it's just a different way to go. I think that's what kept the show alive," he added.

Alexander Calvert, who plays Lucifer's son Jack, summed up the episode in just a few words. "Winchesters. Impala. A bit of mystery," he shared. "What I always like about this show is that, whatever else that happens, it's ultimately about the brothers, and that will be the focus of the 300th episode."

According to the episode description,

Sam (Jared Padalecki) and Dean (Jensen Ackles) look to occult lore for a solution to their latest problem, but instead of a resolution, they find much more than either of them had anticipated. Jeffrey Dean Morgan (John Winchester) guest stars.

John Winchester sacrificed his life to save his son Dean in the Season 2 premiere, though -- as Supernatural fans well know -- Winchesters rarely stay dead on the series. Morgan last appeared on the series in a brief cameo during "All Hell Breaks Loose: Part 2," the Season 2 finale, which aired over a decade ago. Since then, Supernatural has aired aired 12 more seasons; it is currently in the middle of Season 14.

"Lebanon," named after the town in which the Winchester brothers' bunker resides, will air on Thursday, February 7 at 8pm ET.

Airing Thursdays at 8 pm ET/PT on The CW, Supernatural stars Jensen Ackles, Jared Padalecki, Misha Collins and Alexander Calvert.
