After Supernatural reached its climax with 15 seasons in 2020, the reception of the show’s ending has remained mixed among fans. Some fans accepted Dean Winchester’s death, while others argued the show’s ending did not do justice to the grand and monumental tone that was set throughout the series. What if that bittersweet fatal finale was intended all along? What if this had been hinted at seasons earlier — and somehow most fans overlooked it?
The CW series has always captured the audience's meta storytelling approach. With regard to the death of Dean —and in fact the entire 15 seasons— the franchise used boundary-transcending humor that crosses into reality.
Every now and then, breaking the fourth wall, there are books within the universe that foreshadow upcoming episodes, and all of this is directly tied to the existence of Supernatural. Enlightened viewers are rewarded by, through the help of prophecy, literary devices heavily shaken hoisted forward, and Supernatural is the testament of paying close attention.
A strikingly chilling example can be found in Season 9’s final episode, “Do You Believe in Miracles?” where Dean gets stabbed and killed by Metatron, an ex-angel scribe fixated on chronicling tales. At first, it seemed like just another one of the numerous climactic twists Supernatural is filled with, but this moment acts as a gaping reflection of Dean's true death in the series finale — not at the hands of a demon or god, but instead, during a mundane routine hunt within the silence of intimacy.
Metatron’s storytelling obsession foreshadowed Dean’s fate

Metatron was not merely presented as another antagonist: he was a writer too - a celestial author who scripted the world and its happenings. In “Do You Believe in Miracles?”, he creates a sophisticated story where he is the protagonist and leads the events to his favor as an author, not a fighter. His conflict with Dean is more than a fight; it is a compelling plot point. Dean's death at Metatron’s hands feels conclusive - definitive - metaphoric, especially when Dean is then resurrected, thanks to the Mark of Cain.
This moment hits harder when contrasted with the series finale. Dean’s death is portrayed the same way in both instances. He dies facing up, stabbed in the chest. He shares, as usual, a big brother moment with Sam before passing on. There is a great balance between those two scenes, and it feels as if it has been hinting at it. Metatron (a God who isn’t quite there yet) writes,” Dean’s first death scene while Chuck, a veritable playwright, “directs the final one. These moments are hauntingly beautiful, unsurprisingly so, and yet so easy to overlook if you're not actively searching.
Supernatural seasons 7 and 8 planted the seeds of a predetermined ending

Metatron's character was introduced as early as Season 7, Episode 21, in “Reading is Fundamental.” The title itself taps into the profound impact literature can have, while the dialogue has Sam mistaking Metatron for Megatron, an early indication of Metatron’s eventual villainy. In this episode, Supernatural undergoes a shift: the importance of the divine text, the Word of God, now becomes pivotal to the Winchester brothers’ quest.
Metatron arrives in Season 8 and is found living in isolation, encircled by tomes while obsessively scribing tales in his little world. Initially, he aids the Winchesters, but it becomes increasingly apparent that saving the world is not in his interests; rather, he is intent on molding it. Like Chuck, Metatron is deeply interested in foundations, character arcs, and tragedy. He wants to write a better story, just like Chuck attempts to do later in the seasons, framing both as authors of destiny rather than pawns in their narratives.
