SPOILER ALERT: If you haven't watched the Riverdale season 2 finale, get outta this post RN.

A new Riverdale fan theory is surfing the interwebs and it has us shook to our flippin' core. Like all good theories, this beaut started on Reddit.

The general gist of the story is that Penny Peabody (AKA, 'The Snake Charmer') is Betty Cooper's biological mum, NOT Alice.

The argument goes that Alice and Penny are secretly half-sisters and that Penny gave birth to Betty at a young age. But Alice (Betty's aunt) decided Penny wasn't responsible enough to look after Betty, so she took her to the Northside and raised her with Hal to give her a better life.

Penny is now stewing and wants revenge through the Black Hood, to prove to Alice that the Northside ain't all it's cracked up to be.

"Penny is the puppeteer of everything, the mastermind. Someone else is making all the mess for her," the Reddit user writes.

"Alice wanted to repair what she had done with her first child [Chic], she wanted to feel good about herself 'saving' the life of another baby. And that's it. Alice did it," the Redditor continues.

Now, let's unpack this theory and see if there's any substance to it.

For starters, Alice and Penny are BOTH from the Southside. We also have very little info about either of their early lives, so it's totally possible Penny and Alice are related.

Pkus, there's an undeniable resemblance between Penny and Betty.

I mean, they even pull the same facial expression FFS.

And if Penny was Betty's mum, it might help explain her dark side (y'know, apart from the whole 'Hal being the Black Hood' thingo).

On a more scientific matter, when you look at Betty and her sister Polly, it actually makes more sense that the girls have different mothers, as they're probs a LOT closer in age than anyone thinks.

Remember how Polly and Jason were in the same year at Riverdale High? But Jason's twin, Cheryl, is in the same year as Betty, Jughead and Archie. Perhaps putting the sisters in two different grades was a deliberate decision by Alice to make it more believable that they're biological sisters.

Sure, this whole thing might be a bit of a stretch, but it's totally possible.

Whaddaya reckon? Think it's a legit theory, or nah?

Guess we'll just have to wait until season 3 to find out for sure.
