Did you catch all the Riverdale easter eggs in Chilling Adventures of Sabrina?

Hidden Easter eggs in the Chilling Adventures of Sabrina confirm its existence in the Riverdale universe.

Even though Chilling Adventures of Sabrina is a separate series all on its own, its ten-episode first season somewhat confirmed its connection to its sister show, Riverdale. Both series are adaptations from the Archie Comics developed by Roberto Aguirre-Sacasa that share the same world and have had several crossovers in the comics.

This was the original idea for a series starring Sabrina Spellman- The character was supposed to be introduced into Riverdale during its season one finale then become an antagonist for season two. This idea was dropped for various reasons and they decided to make a show about the Spellman witches instead, this again was changed when the series went to Netflix instead of the CW.

Any connection it might have had with Riverdale seemingly died away after the network switch. However, the possibility of a crossover seems to be growing by the day.

Before The Chilling Adventures of Sabrina premiered on October 26, Riverdale season two gave hopes for a shared universe when it referenced the existence of Greendale. Greendale is where Sabrina and the witches live, which is on the opposite side of Sweetwater River, the same river Jason Blossom’s body washed up on the shores of.

In the second season of Riverdale, its neighboring town of Greendale was referred to as a spooky and dangerous place, a place you don’t want to be near after midnight. Ms. Grundy was murdered by the Black Hood in Greendale, and Jughead was strong-armed into delivering a mysterious crate to Greendale by Penny Peabody in the episode, “Tales From the Darkside.”

Sabrina‘s and Riverdale‘s showrunner has mentioned his hopes for a crossover in an interview at NYCC:

"“On Riverdale they are like ‘we can’t crossover because we don’t have supernatural stuff on Riverdale.’ And that’s true… But I always say that the Riverdale kids on a dare could like break into the haunted house in Greendale and it’s ya know the Spellman house on Halloween. It’s about finding the right story and the right time. I think right now the big priority is launching Sabrina as its own thing and making sure that Riverdale as gonzo as it’s ever been.”"

Now, it looks like we’ve gotten some hints at a shared universe as well as a slightly confusing cameo. The Riverdale high school was named dropped in the second episode of Sabrina when a football player tries guessing what high school the Weird Sisters go to, Riverdale was one of their guesses.

There is also another Easter egg in Sabrina‘s lengthy opening credit sequence, where the comic versions of Archie and Betty are shown on a TV show that Sabrina is watching.

Riverdale gets another name drop when Sabrina Spellman’s boyfriend, Harvey Kinkle and his family are making funeral arrangements for Harvey’s brother Tommy. Upon learning of Sabrina’s witch status and of her lies, Harvey refuses to use the Spellman’s mortuary services and calls the funeral home located across Sweetwater River instead.

Aside from all that, there is one character from Riverdale who briefly crosses over. Do you all remember Ben Button, played by Moses Thiessen in Riverdale? He recently committed suicide by falling out a window after playing the game Griffins and Gargoyles. Well, he had a cameo on Sabrina as a pizza boy named Ben, “Ben the Pizza Guy.” He delivers a pizza to Madam Satan and she invites him in, giving the indication that she’s going to eat him. So apparently, Ben’s died twice. Are Sam and Dean Winchester going to make some cameos too? Feels like we’re getting into Supernatural territory here.

When asked by Entertainment Tonight about the strange cameo, showrunner Roberto Aguirre-Sacasa explained

"“That’s a good question, and that depends,” he said. “It suggests a very deep, deep mythology where time and space bends. I love that kid. I’m sad that he keeps turning up and horrible things keep happening to him.”"

Did he survive the fall out the window?

"“It seemed like it was pretty final, but yet there he is in Greendale,” Aguirre-Sacasa continued. “But in Greendale, everyone pops up – the dead don’t stay dead long in Greendale.”"

This is complicated because if Thiessen is playing the same character, then how was he resurrected for this one-time visit to Greendale? Either season one of The Chilling Adventures of Sabrina takes place before the first season of Riverdale or, that Griffins and Gargoyles game really is supernatural. Plus, it might be just me wondering this, but a couple of people have died on Riverdale and they bring Ben in for a cameo? Why?

On a good day, he might have had two or three lines and yet they haul him back from the grave to deliver pizza to Satan’s mistress; stranger things have happened, but it just seems weird. Ben’s minor appearances have always seemed a bit strange and partnered up with fellow oddities. He was in Greendale the night Ms. Grundy was killed by The Black Hood and he was the one who interviewed creepy Chic at the Bijou Movie Theater for a job. Then there’s also the Gargoyle King he sacrificed himself for.

Speaking of the Gargoyle King, is there a chance that the CW is bringing the supernatural to Archie and the gang? The Gargoyle King comes off as something ominously dark and if that’s a guy in a suit than he must be as thin as Slender Man and be on some very high stilts. It seems incredibly unlikely that Jughead and Betty are going to run into some real dark forces during their investigation, it just doesn’t feel like that type of show, but if they’ve always accepted the existence of Sabrina and vice versa then it might be possible.

Thiessen isn’t the only actor who’s crossed over, there’s also Chris Rosamond, who plays both Harvey Kinkle’s father and also a Southside Serpent named Mustang and Reese Alexander plays both Josie’s father in Riverdale and Roz’s father in Sabrina. Thiessen is the only one playing the same character, but seeing similar faces gets the crossover suspicions going again. This could mean something, like Josie and Roz are half-sisters or Mr. Kinkle has a twin brother, or it could be that both shows have the same showrunner and are filmed in Vancouver so they’re double-dipping into the pool of actors there.

Who knows. I’m sure, though, that if there was absolutely no chance of a crossover, the subject would have been dropped, but it keeps coming up in hints and teasing comments.

The Chilling Adventures of Sabrina is currently streaming on Netflix. Riverdale airs on Wednesdays at 8 p.m. ET on the CW.
