With all of the blood,guts, and bashed-in skulls flying around The Walking Dead, or sometimes it's tough to pick up on all the small details the creators slip in to each episode. On top of the insane (but plausible) theory connecting the zombie drama to Breaking Bad,there are a whole host of references to other TV shows and movies, celebrity cameos, and even a trace all the way back in season four that foreshadowed Negan's bloody,brutal arrival. How they find the time to think of all these incredible connections when we're still emotionally scarred from season seven's traumatizing premiere, we'll never know.
