Walter White had used the machine gun to shoot all of the Nazi guys. Jesse choked Todd to death with that chain thingie, and all was good. But Walt had gotten shot by the machine gun. After that, Walt and Jessie look at each other one last time and Jesse escapes. Walt, however, goes to the meth lab to get one last look at the thing that made him feel alive. In the lab, he finds some of his blue meth, a meth bulb, and a lighter. Being that he'll be dead soon, Walt decides to give it a shot. A few minutes later, Walt takes his first (and last) puff of his own creation.

"Wow," he says. "This isn't bad."

Just then, Walt falls flat on the floor. He lay on his stomach, motionless.
