Mike is a motherfucking sav.
***SPOILERS***
Walt's off the hook, for now, with the poison cigarette. There are still loose ends though (Saul/Huel), so that could still play out with Jesse finding out the truth.
Hank and Gomie interrogating Mike was fucking classic.
I could say this about almost every character on the show (barring Skyler, Marie and Walt Jr.), but Hank is one of my favorites. He's gonna play a HUGE role this season, and I'm eager to see what else he can uncover and how close to Walt he'll get. That look he gave, when his chief was saying Gus was right under his nose, kinda implies Hank might know more than he's letting on.
