(Sooo, this is my first theory ever and yup. If you see any misspelled words i’m sorry I can’t talk fluent english) All we know about the black hood killer is that he has green eyes. He thinks that he’s just like Betty and “wants to make” Riverdale a better place. Okay let’s go back to time when the gang discovered that Jason’s killer was Clifford Blossom but technically we could say that Betty and Jughead found that out (mostly Betty) because they were working on the murderboard. Which lead to giving the tape to police and bla bla bla… So after sheriff Keller and mayor Mcoy(sorry if misspelled) saw that Clifford has already commited suicide…But did he??? I got my suspicions about his suicide after Cherryl was threatening her mother about “What really happened in the barn with daddy”. Did Clifford commit suicide, or was it a setup?? Okay here’s the theory: If Clifford didn’t die, he would want revenge right? So he now tortures Betty and Jughead. He did have a tie with the serpents so maybe Juggie being a serpent is really act(from serpents) we did see in this week’s episode that they beated Jughead, Black hood made Betty to break up with him and snake bit him. And for Betty he tortures her mentally because he know what Dark Betty is capable of and is waiting for the right time to finally destroy her. And lastly the thing that would destroy them both is breaking them up. I think the main reason why I think that Clifford is black hood is his eyes and bloodlust(he did kill his son with no hesitation so yeah)?? What do you think? (I’m truly sorry if anything is grammatically incorrect or misspelled)(and I didn’t copy anyone this is my opinion))
