Because yes, Pretty Little Liars and Riverdale exist in the same universe. Why not? ...

The main characters return to Rosewood, the town from the first series of Pretty Little Liars: Original Sin. They learn that some of the patients from Rosewood's Radley Sanitarium were sent to the Sisters of Quiet Mercy over in Riverdale.

Yes, that Riverdale! The Riverdale that is the center of the CWs Riverdale, the show that experimented with Archie comics characters in a non-traditional murder mystery, then became serial killers, cults, and other worlds, with the most recent season culminating with a comet hurtling towards town and catapulting everyone back to the 1950s.

It's official: Pretty Little Liars and the iconic teen paranormal-crime-drama-opera-musical(?)Riverdalenow share a universe.

I assumed that Riverdale would be prohibited from being mentioned because it was in a completely different universe, but it stayed in, according to him. So, yes, I guess it does exist in the same universe.

Alex Aiono was reported to be very open about the idea of a football rivalry between the two high schools in both series.

Aguirre-Sacasa said she would like for there to be a football match between them. Who knows. I don't know how far we'd be permitted to push the shared universes if we did.

Pretty Little Liars was produced by Sara Shepard and ran for seven seasons on Freeform (later known as ABC Family). It followed four separated friends as a mysterious stalker began sending them disturbing texts about their deep hidden secrets. The show ultimately deviated far from the original book series, creating an incredible web of intrigue.

Pretty Little Liars: Original Sin was released earlier this summer on HBO Max, although the previous two shows were brief. Until this episode, they visited Rosewood and met up with a character from the original series (albeit, played by a different actor).

The Chilling Adventures of Sabrina has already been crossed over with Riverdale, although that connection is a little more difficult to explain. Lucy Hale, who played Aria Montgomery in Pretty Little Liars, has also played Katy Keene in the Riverdale spinoff of the same name.

The original author of the Pretty Little Liars books has yet to speak up. The next question to figure out is: Where does Glee fit in?
