I see Walt/Heisenberg/Ozy almost like a multi-personality disorder brought on by extreme stress and chemotherapy.

I also love the fact that the writers were able to essentially lift text right off of forums where people posted hateful rants about Skyler and put those views into Walt's mouth. It was the best and most subtle way to condemn the audience troll viewpoint that wives should all just shut up and follow along.

I do think the episode would have been stronger if Walt Jr. was accidentally seriously hurt during the knife fight. Not killed necessarily, maybe blinded by his parents' blade. That would have brought home a lot of the 'family' themes his character is based on.
