Continuity mistake: Setrakian was born in 1921 and taken to Treblinka when he is 18-years old, that should be in 1939. The episode timeline states that he's taken to Treblinka's in 1944, which would make him 24/25 years old in this scene. (00:08:00 - 00:09:00)
Continuity mistake: Fet is in the sewer looking for rats and encounters a group of infected. He is holding a handkerchief to his face with his left hand to mask the smell. He has his flashlight in his right hand, and pulls out an iron bar with his left. As the camera angle changes, his left hand is again covering his mouth with the handkerchief (no iron bar), then the angle changes again, and he's holding the iron bar again. (00:35:05)
Continuity mistake: Goodweather and Setrakian find the body of Ansel's wife hanging in the stairwell of their home. When Goodweather removes the suicide note from her hand, a rosary is dangling loosely from her wrist. When the shot cuts to a viewpoint from behind her, the rosary is now entwined around her fingers. Then it changes back to hanging from her wrist again.
Continuity mistake: During the flashback scene, when the young Setrakian is attempting to hide his crushed fingers, both hands are wrapped in cloth strips. Eichorn unwraps Setrakian's left hand to inspect it, then sends Setrakian to the group that is to be immediately executed. Moments later, the wrap is still on, but when Setrakian is forced to kneel, his right hand is suddenly bare. There was no time to remove the other wrapping nor could Setrakian have done it himself, his fingers were too severely damaged.
Continuity mistake: When Eph and Nora become passionate while they are at Eph's former home, Eph is wearing a thick, outdoorsy-type jacket. Eph picks Nora up off the bed and carries her over to the bedroom wall, still wearing the jacket. The shot changes angle, and even though he never sets her down and she is tightly clinging to him with her arms and legs wrapped around his body, he instantaneously no longer has the jacket on and is wearing a sweater. He never had time to take the coat off and never set Nora down.
Continuity mistake: After Coco Marchand's emergency surgery for a serious gunshot wound to the chest, she is seen recovering in bed, in a coma, on a respirator, possibly permanently brain-damaged, and in critical condition. A few hours later, when Eldridge Palmer is sitting by her bedside, Coco is suddenly without the respirator and there is no physical sign (bandages, tubes, stitches, bloodstains, etc.) whatsoever of her just having had extensive thoracic surgery for a near-fatal injury. There is only an IV line in her arm. This is before The Master arrives and revives her, and Palmer did not know if/when The Master would come, so he would not have had the respirator removed.
Tainted Love - S4-E6
Continuity mistake: Near the start of the episode when Quinlan is talking to Roman while they load up the truck, Roman puts a green bag next to a black case with the case on the right. He then puts a black bag on top of the black case. After Quinlan passes him another black bag, the green bag and black case have swapped positions and the first black bag has vanished.
