Episode #1.1 - S1-E1
Continuity mistake: When Yu-jin sees his parents being threatened by Lord Kim's men, he puts down the branches he was carrying and moves the stick he was holding from his left hand to his right hand. He then starts running and the stick is now back in his left hand. (00:12:43)
Episode #1.1 - S1-E1
Continuity mistake: After the scene where they suggest increasing the number of men in the ganghwa area, Lord Kim is sitting at a table speaking with another man. In the shot where Kim sighs deeply, a woman can be seen walking past in the background. Then it cuts to a closer shot of Kim and the woman suddenly disappears. (00:09:02)
Continuity mistake: Eugene finds the list of Righteous Army members, folds it up and puts it in his jacket pocket. In the shot of him putting the list in his pocket, both his left hand (holding onto the jacket) and his right hand (putting the list into his pocket) are level with each other. In the next shot, someone walks into the room and his hands don't change position. When the shot cuts back to Eugene, his left hand is much lower down than the right. (00:02:25)
Revealing mistake: When Ms. Haman is shot by the soldiers, the moment that the gunshot that hits her is heard, and she is shot, there is already a massive, thick blood stain on her dress from where she is bleeding from. No gunshot wound on the planet can create an amount of blood that massive or thick in an instant. The blood stain was likely applied to her dress before filming the shot. (01:17:52)
Continuity mistake: When the general shoots the elderly rebel, there is a huge blood stain left on his clothes where the left-hand side of his upper chest is located. When he collapses on the ground in the next shot, the blood stain has suddenly disappeared from his clothing. (01:13:23)
Continuity mistake: When Eugene is hiding inside the rickshaw after being rescued by the rebels, just as he says "She's injured", he is shown holding a gun, but his fingers are not placed on the magazine. When it cuts to a closer shot of him, his fingers are suddenly placed over the magazine. (00:17:14)
Continuity mistake: Eugene is leaving the American legation in Japan by sitting on the back of a truck. In the shot of him sitting down, the bottom of his jacket can be seen going over the side of the truck (positioned behind him). When the truck starts to drive away a few seconds later, the bottom of his jacket is now shown hanging over the back of the truck (positioned to the side of him). (00:12:51)
Factual error: Eugene is given a return order from the President telling him to return to America. The name of the President listed on the order is Franklin D. Roosevelt, but he did not become President until 1933. In 1904, when the episode takes place, Theodore Roosevelt was the President. (01:08:16)
Plot hole: At the end of the previous episode, Ms. Haman is shot by a Japanese soldier. The shot is severe enough to make her collapse to the ground and fall unconscious. But in this episode, she appears perfectly fine without any sign of being shot, and without any injury in sight. (00:07:30)
Factual error: On the wooden globe in Eugene's office, China is listed with the name "People's Republic of China." This name was not first proclaimed until 1949, whereas this episode takes place in 1903. (00:27:28)
Continuity mistake: When Hina is sword fighting with the Japanese soldier, and he slips over, in the overview shot, he is shown dropping his sword. When they go to help him up a few seconds later, the sword is now in his hand. (00:16:48)
Continuity mistake: When Moore is speaking with Minister Allen about continuing the investigation into Joseph's death, just after he finishes saying "It was a missionary who died", Allen can be seen lowering his hands. The camera then changes angles to focus on Moore, and we can Allen lowering his hands a second time. (00:39:53)
Continuity mistake: When Hina is talking with the hotel employee, in the shot where the employee says "The rickshaws bumped into each other", she is holding a cigarette at a vertical angle. When the shot cuts, the cigarette is being held at an upright angle. Then when the shot cuts again, the cigarette is at a vertical angle again. (00:37:30)
Continuity mistake: When Eugene begins eating the piece of paper, in one shot some of the paper can still be seen outside his mouth. When the shot cuts to focus on Moore, none of the paper can be seen outside his mouth. It is now entirely in his mouth even though it wasn't in the previous shot. (00:53:13)
Continuity mistake: Whilst Hina and Leo are fencing together, the match ends with Hina pressing her sword against his chest. The sword can be seen bending when she does this, but when Leo starts saying "Whoa, whoa, whoa", the sword is at a straight angle. (01:01:51)
Continuity mistake: When Hina is talking with Su-mi in the reception, she calls for a worker holding a tray of beer bottles. In the shot where the worker walks up to them, the bottle shown towards the right side of the tray is in a position where the label is facing towards Hina. When the camera changes angles, the bottle is now in a position where the label is facing the opposite direction. (00:55:53)
Episode #1.7 - S1-E7
Continuity mistake: When Eugene finds the Pawn Certificate in the book, he unfolds it and holds it with four fingers on the back and his thumb on the front. When the camera shows a close-up of the certificate, he now has two fingers (as well as his thumb) over the front. (01:05:43)
Episode #1.7 - S1-E7
Continuity mistake: Tsuda grabs So-a by the hair and takes her outside. When the two begin to walk outside, Tsuda does not hit So-a, but when they are outside there are suddenly blood stains on her face, even though Tsuda does not hit her until a few seconds after going outside. (00:46:55)
Episode #1.6 - S1-E6
Continuity mistake: When Eugene and Moore are eating, after Moore asks "Can we get two more bowls over here" and Eugene replies "No", Moore asks "Where did she go", and it cuts to a wide shot of the area. In the shot, we can see Eugene has his wooden spoon pointed downwards in the food, but in the next shot, the spoon is held at a vertical angle. (00:22:05)
Episode #1.5 - S1-E5
Continuity mistake: Ms. Haman is shown placing a vase filled with flowers down on a desk. In the first shot, her right hand is around the top of the vase, while her left is near the bottom. In the next shot, both hands are near the top. (00:19:40)
