I suspect that Sabrina's world will get even darker now that she's signed the Book of the Beast (and become a platinum blonde), but just how wicked will she be? The final scene of the series shows Sabrina walking the halls of the Academy of Unseen Arts alongside the Weird Sisters, wearing their signature lace-collar dress. This can only spell drama, as far as I'm concerned. And to be totally honest, I'm ready for Sabrina to lean farther into her witch side.
