The latest fan theory for season 2 of Riverdale is actually mind-blowing

It actually makes so much sense though...

The latest fan theory about season 2 of Riverdale is actually pretty damn mind blowing. 

***Drum roll please***

Well, we all know that Betty Cooper has a secret brother after watching season 1... but who IS thay mystery brother??

Well, according to this fan theory we now know who he is.

Reddit user RandomFranticAction suggests Betty's brother is someone we already know.... Kevin's boyfriend, Joaquin DeSantos.

That's right, Betty's brother might be a Serpent!!!

This theory also holds up the fact that they could even have different dads.
