"I see something in you. Something good. You don't see it yet, but I do."A regular occurrence of this film, almost like a running gag, is Walter's door, and the people who knock on it.
Every time the door to his apartment gets knocked on, we feel that Walter's patience dwindles by another percentage. Serenity in his solitude is something he initially sets out for.
Solemn grace inside his own walls, not the walls of a prison sentence on a 12 year stretch.
