Breaking Bad's final season opens with a flash

I don’t mean Jesse doesn’t have qualms, but I do think he’s written to suggest there’s a dark core already in there, which responds to, feeds off and is in turn fed by Walter.

Great? He became everything he imagined at the beginning, the baller “tough crystal slinger.” That the price he paid to get there was too high, and that the reality was tainted, is a different problem.

Just like Walter, Jesse wants to believe something about himself that isn’t true; the difference is that unlike Walter, he’s not a sociopath and can’t keep it compartmentalized.
