Agatha All Along showrunner explains why there was no post-credits scene (and what it could've been)
Agatha All Along follows a coven of witches traveling the Witches' Road in hopes of obtaining that which they most desire. Unfortunately, it was ultimately revealed there wasn't a prize at the end of the path for Agatha and audiences alike. The highly acclaimed series broke the long-standing tradition in the Marvel Cinematic Universe of teasing what's to come with a post-credits scene. It seemed like a strange decision, especially since many things could've been set up.
What happened to Death? Is Wanda really "gone"? Where is Billy's brother, Tommy? The seeds for any of these storylines could've been planted during a post-credits scene and yet we got nothing. Audiences fast-forwarded until the end of the last episode only to find a black screen. But in a strange turn of events, we learned it wasn't always meant to be this way.
There were several ideas of what could've been shown, which begs the question: Why did none of them make their way into the series?
Marvel told Agatha All Along showrunner not to do a post-credits scene
As reported by Variety, Agatha All Along showrunner Jac Schaeffer was instructed not to add any post-credits scenes to the series. It comes as quite a shock since Marvel Studios - the studio responsible for popularizing that concept - was the one to kill our hopes of witnessing what's to come:
"That’s a Marvel decision. I know nothing more than that (...) I wrote a number of tags because you always do on every Marvel everything. I love writing tags (...) They’re the best. But there are so many things that factor into those. And I was told that we weren’t going to do a tag on this show."
- Jac Schaeffer
The only mystery bigger than Tommy's whereabouts is the mystery of why Marvel would cut a post-credits scene. Maybe Agatha's and Wiccan's stories will be followed up sooner than expected, so it wouldn't make sense to tease what's coming in such a short time of anticipation. On the other hand, perhaps they're still planning what to do with the characters and they don't want to have any restrictions moving forward.
The post-credits scene of WandaVision showed the Scarlet Witch using the Darkhold, meaning any project she appeared in next had to see her corrupted by the book's power. That storyline eventually happened in Doctor Strange in the Multiverse of Madness and we all know the movie wasn't exactly a fan favorite. Part of the problem is how Wanda just turned into a straight villain since the last time we saw her with no further development, all in an attempt to follow up with that one post-credits scene. So perhaps Marvel doesn't want to repeat the same mistake moving forward.
Regardless of why the scene was cut, it also makes us wonder what it was supposed to be like. Chances are Marvel will keep the secret to themselves, but it doesn't mean we can't look elsewhere for answers. Insider MyTimeToShineHello reported there were three different ideas on the table. The first one would've seen Sasheer Zamata's Jennifer Kale hunting the Doctor who bound her all those years ago (courtesy of Agatha). A second option would've showcased Death following Agatha and Wiccan after they go looking for Tommy; hinting their conflict is far from over. The final alternative was a simple scene of the Witches' Road disintegrating after Wiccan left the town looking for his brother.
Perhaps we'll be able to see one of these scenes come to life in a future project. Until then, it's okay to rewatch Agatha All Along over and over again to make the wait feel shorter.
