Has there been any discussion or thoughts about how some events or themes are repeated twice during the series?
It could be a stretch, and maybe some are repeated more than twice, but the more I think about it the more examples I come up with.
And of course I may be wrong about some I have listed, the whole series is hard to remember all the details of dialogue, so feel free to set me straight. Also, some examples I have read right here on this Wiki.
Walter is handcuffed in the dessert twice.
Walter's pants from the RV that he loses in the desert are seen twice.
Walter wears the same clothes in the pilot episode as the final episode.
Walter and Gus both have a scene where they have their cheek to the ground, mouths open, crying silently in pain after someone close to them is shot in the head
Jesse uses a gun to kill 2 people in the series
Jesse has 2 love relationships in the series (although he is with Wendy the prostitute, I didn't count that as a love relationship)
Walter Jr gets a new musculecar...twice
Walter shoots 2 people in the head in the series
And so on, just to name a few.
