This is a Gif recap, but in case I need to spell it out, spoilers ahead.
The season premiere of Breaking Bad begins with our old friend and meth-lab assistant Gale Boetticher wielding a box cutter. Given the season 3 finale, which saw Jesse shooting(?) Gale in cold blood, we can immediately assume we are witnessing a flash back to a happier time…a time when Gale still had the back of his skull intact.
During the course of the flashback, Gale gleefully sets up his new lab. He looks like a kid in a candy store, and boasts about how the equipment would be at home with any of the larger pharmaceutical companies. But when the topic turns to Walter White‘s meth, the boasting comes to a halt, and Gale humbly admits to Gus that his own product is nowhere near the purity of their competitor’s. The admission seems almost pathetic, considering we know that Gale has just inadvertently signed his own death warrant.
Flash forward to the present day. Jesse has just shot Gale in the face, and concerned neighbors are milling about outside the apartment, waiting for police to arrive. Victor arrives instead, and confirms that his employer’s scientist has been killed.
