20 Things You Somehow Missed In Breaking Bad
10. The Death Of Walter White
The end of the episode, "Crawl Space" is famous amongst fans for its intense ending in which an overwhelmed Walt has a hysterical laughing fit. Many fans have remarked that this moment causes "the end" of Walter White, and therefore, "the birth" of Heisenberg.
The shot is then replicated in the very final shot of the series, where Walt has been shot and killed by the police.
Therefore, both of these shots symbolise the death of something - first of Walter White himself and then of Heisenberg.
