10 Breaking Bad Mistakes Nobody Noticed
4. Where's Walt's Scar?
By the time the show's final season comes about, Walter White has completely given in to his kingpin Heisenberg persona and becomes a complete monster to his family, the very people he had initially started out trying to provide for. After helping to kill off Hank, he desperately makes one last attempt to get his family to follow him into exile, which they naturally don't embrace much.
Things grow from heated to outright destructive as the family clash, with Skyler arming herself with a kitchen knife and slashing at Walt's hand. The entire sequence is unsettling and uncomfortable to watch, but the direction from behind the camera makes a real point to show off just how deep a slash this cut to Walt's hand is.
So, why then does the show never a scar of the attack on Walt's hand going forward? There are two more episodes in the original run of the show following the attack and although these episodes do take place a year later, there's no way Walt would have emerged from an attack like that without a battle scar to point to and show off.
