BuzzFeed Spotlight featuring Jason Rostovsky, writer of "Agatha All Along Episode 6," with two stills from the show

1.First, Agatha All Along writer Jason Rostovsky said it was "really easy" but also "really challenging trying to put all these pieces together" when it came to exploring how William Kaplan became Billy Maximoff and what ultimately led him to the Witches' Road and Agatha.

2.Jason added that it was a real "collaborative experience" in the writers' room when it came to crafting how Billy Maximoff/Wiccan would finally be introduced into the Marvel Cinematic Universe.

3.When it came to introducing Billy/Wiccan to the MCU, it was important to the writers to "use things that were canon for him" from the comics in Agatha All Along, but also make his story surprising for comic book readers, too.

4.Incorporating William Kaplan's Jewish heritage from the comics into the show was exciting for Jason, who said, "In the lead-up to writing, I went back and watched my own bar mitzvah video, which was equal parts inspiring and traumatic at the same time, but it really did sort of open up a lot of what that could look like."

5.Not only did Episode 6 involve merging William Kaplan and Billy Maximoff's stories, but it also flipped Teen's motives, a character we'd been with since Episode 1. Jason said it was also exciting exploring Teen in a new way, too.

"He's somebody who's a bit more like a fanboy of witches, and then we learn who he really is in multiple ways. I think it was just a lot of fun finding all these different facets and elements and personas of Billy," he told BuzzFeed.

6.Jac Schaeffer knew she wanted to bring back Evan Peters's Ralph Bohner for Agatha All Along. It just wasn't always clear when and where he'd appear. Eventually the writers' room came up with having him be a great person to fill Billy in on what happened in Westview during WandaVision.

7.While Evan Peters was in a lot of WandaVision, Episode 6 of Agatha All Along is the first time we spend a prolonged period of time with the real Ralph. Jason said it was exciting exploring the "paranoid, traumatized character and looking into what it really looks like for the people of Westview who really had it bad."

8.Jac Schaeffer knew that showing Agatha's detective story through the eyes of Billy in Episode 6 needed to be "more comedic" and have it be the total opposite of the "very prestigious, very badass persona" Agatha was imagining in Episode 1.

9.The fun details and Easter eggs in the detective scenes were a collaborative effort between the Agatha All Along writers. Agatha using a hose nozzle as a gun was an early idea, and there was even a version where she "draws it and [it] dribbles some water, very sadly."

10.The interrogation scene between Billy and Agatha included some improv, including the "poke the bear" moment.

11.According to Jason, Evan Peters brought a lot to Ralph's return that wasn't written on the page. For example, Evan "built some of his witch kit" and he "came up with the witch spray" moment.

"That was just hilarious," Jason began. "It's so cool to see somebody come to the table with so much and really build out that character more than was on the page. So that was a great improvised part that I loved."

12.The "most challenging" scene to write in Episode 6 is when we return to the Witches' Road and Agatha and Teen "reunite," with Agatha finally knowing that Teen is Billy Maximoff.

13.Having Billy's motive for being on the Witches' Road be to find Tommy was a "really important piece" for the writers, and it "felt natural" that Billy would be trying to find "the other half of himself."

14.One of Jason's favorite moments is when we find out Lilia is the one who placed the sigil on Billy. He said, "Here's Lilia doing something wonderful for this kid and trying to protect this boy that she cares a lot about."

15.And finally, it was important for Jason to include all of the coven members in Billy's backstory and connect them all. He said, "I definitely had chills watching it, and I really felt the power of them all existing as a part of his life before we get to the road and form this coven for real."
