Breaking Bad’s meth exists in The Walking Dead. Merle had some in his bag of drugs in season one.
This means that both shows take place in the same universe.
I want the series finale of BrBa to end with an infected batch of Blue Sky getting shipped out across New Mexico and the Czech Republic, thus starting the zombie outbreak.
How amazing would that be, if BrBa was just a prequel to TWD the whole time?!
