When Walt and Jesse are discussing business in the RV, the hood on Walt's suit is constantly changing between being flat and being folded over.
Hank enters his garage in the middle of the night, and when Marie suddenly shows up on another door, he aims his gun and flashlight at her, then at the beer bottles when they burst. He is then shown lowering both, but when the camera cuts back to Marie, light is still on her as if Hank was still aiming at her.
Early in the episode we see Walt arrive at the house during the day with Skylar on the phone at the dining room table, the patio doors letting lots of sunshine into the room. When we see Walt at an angle with the kitchen behind him, that room is completely dark and not visible - since the kitchen has its own window it should also be bright with sunshine.
When Skinny Pete, Badger, and Combo come over to Jesse's, the knocking sound continues after the person at the door, in silhouette, has stopped knocking.
When Hank throws the clear cube into the river the river (video) speeds up just before the cube hits the water but the sound associated with the river & cars in the background remain the same.
Jesse incorrectly describes the one ounce shortfall in drugs as 'breakage'. 'Breakage' refers to credit for a service or product that a customer receives but does not use. The correct word to describe items that disappear from an inventory is 'shrinkage'. Jesse of course may not know these accounting terms.
