In case you’ve been living in an underground meth lab for the last few years, let us remind you: the end of Breaking Bad is nigh. There are only four episodes left in the acclaimed AMC crime drama’s five-season run. Questions abound: Will high school chemistry teacher Walter White (Bryan Cranston) pay dearly for becoming a murdering meth lord? Or will he somehow dig a way out of the mess that he’s created? Will his ex-partner Jesse (Aaron Paul) and DEA brother-in-law Hank (Dean Norris) — or his advancing cancer — exact revenge on him? Will anyone order the tableside guacamole?
