The Eagle and the Osprey - S6-E1
Other mistake: When Walt is at his home waiting for a callback about the trace, his landline rings. However, the subtitles say [cellphone rings]. It's well established Walt doesn't have a cellphone.
A Thing I'll Never Understand - S6-E4
Continuity mistake: When Vic is crying, she lays in Walt's lap and puts both her hands on his thigh and Walt's hand is on her arm/shoulder. In the next shot, Vic's hand is covering her mouth and Walt's hand is on his knee.
A Thing I'll Never Understand - S6-E4
Continuity mistake: When Travis is talking to Henry at the bar, the bill he puts on the counter keeps changing positions in various shots. For example, sometimes it's lying horizontally and sometimes it's lying vertically.
Continuity mistake: After Lucian jumps off the edge and Walt turns him over, Lucian has dirt on the side of his head by the blood. In some shots the dirt is gone, but then back in later shots.
No Greater Character Endorsement - S6-E6
Continuity mistake: At the tribal council hearing, when they vote to oppose, 7 of the 8 raise their right hand (the man at the end raises his left hand). But in the close up panning shot of the raised hands, the guy sitting next to Jacob Nighthorse has his left hand raised. It's back to his right hand when they lower their hands.
Opiates and Antibiotics - S6-E7
Factual error: When we see Eddie Harp's driver's license, it expires 8 years after it was issued. However, Massachusetts driver's license are only valid for 5 years and expire on the person's birthday, not the issue date.
Goodbye Is Always Implied - S6-E10
Continuity mistake: Near the end, when Vic is on the porch bench, she's holding a mug in her hand. When Walt goes to sit down, she's still holding it, but in the next shot her hands are empty and the mug is on the porch railing.
Answer: Chance.
