that dinner scene is what defines a show's legacy...walt's run down, his simple yet emotional way of showing jessie just why he can't let the game go...
the off putting looks jesse made as he ate the food, skylars cocky motions as she admits she slept outside her marriage and walt looking unphased before she leaves them...Walt explaining his kids were gone and his wife wanted him to die. Him saying meth was all he had to live for...that to me seals the fact that walt is now the villain. The dirt before all supposedly had a good purpose but its clear he is a megalomaniac, bent on becoming the most powerful underworld boss and spreading meth accross the entire us and making more money than his old business ever did.
As some one said, not since Arrested Development imo, has a writing team played up this much detail in to a script without jumping the shark. It's a shame and a gift this has to end next year
