spoilers, riverdale s5, sabrina s4, speculation
I don't remember which recap podcast I was listening to that pointed out Riverdale specifically stated it was 2020 before the time jump and now 7 years later someone specifically said it's 2021.
In the latest episode there's mysterious lights in the sky and abductions.
I'm just gonna say a Sabrina crossover would go really well here. They did do time hijinks that would overlap and Ambrose does autopsies, so.
If it's not witches it should be.
