Plot hole: The very ending scene where Peter (in this version died in the ice as a boy so Walter's wife never met him) takes off some of the dust covers then picks up a toy airplane. The toy airplane he got as a child from ... Walter's wife when she was trying to placate him in an earlier episode for trying to run "home". This toy airplane wouldn't have been his as a child in this version of the universe. (00:42:00)juarlita
Plot hole: Preparing to steal methylamine from the train, Walt, Jesse and Mike measure off a predetermined distance from the railroad crossing, which happens to coincide with a handy arroyo, where they bury their tanks. Problem is that they couldn't have known that distance (calculated by knowing the position of the methylamine tanker car in the train) until Lydia told them. But she didn't call that info in until the night after they'd already buried the tanks.Rattletrap
Plot hole: When Lawquane spots the droids in the field, he identifies them instantly as commando droids. But as he had left the Republic Army shortly after the first battle on Geonosis (the one which started the war) and has lived as a farmer ever since, and since the commando droids are relatively new (see "Rookies"), how can he know what they are? With his lack of battlefield experience, he should simply call them battle droids.Daniel4646
Plot hole: In the episode where Jessica went home to her family's house in season 2, Bill said "someone who lives here must invite me in." In this episode, Russell Edgington's wolf (Coota) invites Russell into Alcide's apartment. Also, in Season 6 Sarah Newlin recinds Jessica's invitation into Jason's house (which only Jason should be able to do).
Plot hole: When the guys break into the safe house and free the witness against Bobby, they are wearing masks to hide their identities. Yet after freeing the witness, Jax and Tig decide to get involved in a fist fight inside the house which would leave their DNA all over the place. Since both are undoubtedly on the police database, it would take no time at all for the police to find at least two of the culprits who assaulted two officers, an ATF agent and intimidated their star witness.The_Iceman
Plot hole: Just after Lex teleports into the Bat Cave, he marvels over how their tracking devices worked perfectly. However, they didn't have the plan to switch up nemeses until after they had their butts handed to them and retreated back to the Lex's lair. They never had the chance to put any tracers on the heroes, nor did they even have the idea to beforehand. (00:14:15)Quantom X
Plot hole: In the heat of killing fake Red John, Jane forgot to notice that Craig O'Laughlin never knew about the mall setup to lure Red John. So definitely Gale Bertram himself was in contact with the serial killer which he may have missed first up, but all that time in jail afterwards he could have figured it out.
