Supernatural‘s season 12 finale saw Mary Winchester make some big moves. Most notably, she showed up with her warded brass knuckles and decided to go toe-to-toe with Lucifer himself, a decision that ultimately landed her trapped in the apocalypse world for the foreseeable future. But before she made her way to that house and helped Kelly Kline give birth to Lucifer’s son, she had a heart-to-heart with her boys … one fans didn’t get to see.
EW has an exclusive first look at a deleted scene from the finale, in which Sam and Dean are preparing to take on Lucifer and an emotional Mary pleads with her sons: “I just got you back. I can’t lose you,” she tells them. But Dean promises her she won’t. (And technically, he’s right, because, in the end, they’re the ones who lose her.)
Watch the deleted scene above and then take your own copy home when Supernatural‘s twelfth season is released on Blu-ray and DVD on Sept. 5.
