We've heard some pretty crazy theories in the past, like how the 'Black Hood' might actually be Archie's dog Vegas... but this new theory about the show is even more wild.
It suggests that Alice Cooper isn't really Betty's mum.
Reddit user -lCrackers suggests that the South Side’s lawyer, Penny Peabody, is actually Betty’s biological mum. It's also suggested in the theory that Penny and Alice are half-sisters.
The theory follows that Alice took Betty away from Penny when she was born, because she didn't think she was able to have her own child. Now, Penny is out to get revenge on Alice for taking her daughter, and for making the Southside look like a criminal infestation.
We could kind of get around this theory! Tell us what you think of it.
