Selective morals? How is that a valid defense of Jesse's crybaby bullshit?
People choose to use meth. Drew Sharp didn't have that choice. Wrong time, wrong place. Didn't even understand what he was seeing. Murder was an excessive response to the encounter. Jesse understood that. I'm not sure what you're arguing. That Jesse is somehow in the wrong to be troubled by the needless murder of a kid? I'm not crazy about this particular plot turn/device, but that seems a natural enough reaction to me. If you're saying Jesse is a little picky-choosy about which transgressions get under his skin, that is probably true. Jesse's a fallible human. Child murder seems a reasonable transgression for his still very active conscience to be rattled by.
To Walt the entire encounter and outcome is simply a business event. Not one he's happy about, but any unhappiness he experiences arises not from human compassion for the life taken, but its effect on his operation and crew morale. I like the way the show illustrates the link between evil and the efficient machinations of the self-made man.
So addiction doesn't exist?
You can't become physically addicted until you've already chosen to repeatedly use it.
I was surprised the episode didn't end when Hank closed the garage door.
Oo. That would've been cruel. I hadn't thought of that.
The flash-forward in the beginning is at least a few years in the future. So, no, Walt will not be dead of cancer soon. There has been no story about that side of Walt's life recently, and not showing every excruciating detail is just not in Gilligan's playbook (they've got way too many hours of TV to fill). Walt is lying about his cancer coming back.
It's the day of his 52nd birthday, two years after the start of the whole series. It's not "a few years into the future." I'm not sure where we are on the timeline, but birthday 51 already elapsed. It was mentioned before that the two-year timeline of the show presents some significant plausibility problems -- but, plausible or no, that's the timeline. What we're seeing in the opening is probably a few months into the future, not years.
And no way Walt's lying about the cancer. Not a terrible idea, but they show him receiving chemo again, and the coughing during the first Season 5 flash-forward was a giveaway even before this new half-season began.
