The Breaking Bad season 5 finale, or the “final episode of 2012″ as described by AMC, was a stunner as we watched shocking events occur.

Now series creator Vince Gilligan and his cast are explaining how and why things happened the way they did.

This behind the scenes look released by the network includes interviews with Gilligan, Bryan Cranston, Anna Gunn, and Dean Norris amongst others.

We’re still pretty shocked that Walt decided to give up the business, after spending most of this season so far convincing people like Jesse that he will never stop.
