If you do kill Stefan’s dad and cut up the body, this has the effect of giving Stefan and kind of sick euphoria, which allows him to complete the code for the game. This, weirdly, might be the happiest ending. Yes, Stefan goes to jail in this version, but everyone loves the game. During the credits, there’s a flashforward to the future where its revealed that Colin’s grown-daughter Pearl is reviving Bandersnatch for a streaming platform. It’s pretty twisted, but it feels like the most appropriate kind of ending for a Black Mirror episode. Dark, scary and a little bit meta.
