6 Riverdale Theories So Crazy, They Might Come True

Penny Peabody has been the center of so many fan theories, but this one seems to be the most popular by far. Started by a fan on Reddit, the theory suggests that Penny is actually the sister of Alice Cooper and also secretly Betty's biological mom. This would explain her seeming resentment towards Betty, as well as her reluctance to off Jughead when the opportunity arises (maybe she didn't want to hurt her daughter). This one's a bit far-fetched, but on Riverdale, nothing is too far-fetched to happen!
