BREAKING BAD IS A PREQUEL TO THE WALKING DEAD - At the end of Breaking Bad, Walter White’s (Bryan Cranston) blue meth is becoming more and more popular across the country, eventually making its way around the world. Some fans think that users die, only to rise again in zombie form. Those who subscribe to this theory point to the handful of Breaking Bad references on The Walking Dead. In season one, Glenn (Stephen Yeun) drives a red Dodge Challenger, which looks very similar to Walter White’s car. And when Walter White goes to return his Dodge on Breaking Bad, he takes it back to the dealership’s general manager, whose name is also Glenn. In season two, Daryl Dixon (Norman Reedus) is trying to bring down T-Dog’s (IronE Singleton) injury-induced fever, so he pulls out his brother Merle's stash of drugs to see if anything in the plastic bag will do the trick. Pictured clearly at the bottom of the bag: blue crystal meth. Even more suspicious: before the zombie apocalypse, Merle Dixon (Michael Rooker) used to be a drug dealer. His supplier was described as “a janky little white guy” who threatened Merle with a gun and said, "I'm gonna kill you, bitch!" Sounds like Jesse Pinkman (Aaron Paul) to me.
