Continuity mistake: When Dani is looking at Simon and Connie complaining to Ingemar after the female elder jumps off the cliff and they turn back to face towards it, Christian says "Oh my God" realising the male elder is about to jump off. At this moment, he has his left hand over his mouth and his right hand by his side. The shot then cuts and Christian now has his right hand over his mouth and his left hand on his chest. (01:10:55)
Continuity mistake: When the female elder is standing at the edge of the cliff, in an overview shot of the Hårgas, Dani, Christian, Josh and Pelle's shadows are in front of them. A couple seconds later, when the camera is slightly panning down on the four, their shadows are to the right of them. (01:08:55)
Continuity mistake: In the first shot of the Hårgas looking up at the cliff, when the camera pans over to Dani, Christian, Pelle and Josh, Pelle is standing a couple of feet away from the other three. When the camera changes angles to the cliff, Pelle is standing right next to the other three. (01:05:55)
Continuity mistake: When Pelle is explaining how the Hårgas roles work depending on their age, as he says "And finally from 54 to 72, you become a mentor", Christian is behind Pelle facing towards him. The shot changes angles, Christian's body is in a different direction and then turns his head to face Pelle. The shot changes angles again and Christian is now suddenly looking upwards. (00:53:30)
Continuity mistake: In the first meal scene, when Josh asks Pelle for a translation of what the Hårga was singing and Christian asks for one as well, Dani is shown eating out of a bowl and holding a fork, then lowers the bowl and fork as Christian says "Yeah, thanks. That would be amazing." It then cuts to a different angle, where Dani suddenly has food on the fork and the bowl is raised again. (Director's Cut). (00:47:25)
Continuity mistake: When Ingemar shows everyone the mushrooms and Mark goes to reach for them, Pelle is scratching his head and begins to lower his arm. The camera changes angles and his arms are suddenly folded. (00:30:38)
Continuity mistake: When Pelle and Ingemar first reunite in Halsingland, the shadows they cast on the ground are small and light and positioned directly in front of them. Later in the scene, when Mark takes the mushrooms from Ingemar, the shadows are now more deeper and positioned more to a 2 o'clock direction. (00:29:50 - 00:30:40)
Continuity mistake: When the group are in the car driving through Sweden, after Mark asks what is it that makes the women hotter, it cuts to Dani and Christian is shown sitting next to her. His arm is positioned so that his wrist is touching her shoulder. The camera changes angles and his arm is suddenly pulled away from her. (00:25:30)
Continuity mistake: When Dani is speaking to Pelle before the trip to Sweden, she is shown wearing a hoodie that is zipped open slightly. The left side of the hoodie is opened out revealing some white stitching along the interior of the zipper. She then moves to the couch that Pelle is sitting on and the right side of the hoodie is now opened out. (00:23:10)
Continuity mistake: When Dani and Christian are at her apartment after returning from the party, Christian sits down on the couch with her and places his hand on his head in a position where his knuckle is touching his head. It then cuts to Christian saying "It's fine", and it is now his fingers touching his head. (Director's Cut). (00:18:40)
Continuity mistake: When Christian is trying to explain when they will be going on the trip to Sweden to Dani, as he says "I'm probably not gonna go", Mark is holding a bottle upright. The camera changes angles and the bottle he is holding is suddenly titled forwards slightly. (00:14:45)
Continuity mistake: At the party, when talking about the trip to Sweden, just after Mark says Pelle's invited them to an authentic hippie midsummer at his yodelling farm, it cuts to Dani asking "Oh, yeah." To the right of shot, Mark is shown holding a bottle with part of the label slightly uncovered, while the rest is covered by his hand. Two shots after, in a shot of the whole group, Mark's hand is now entirely covering the label. (00:14:20)
Continuity mistake: When Josh asks Pelle if he's not talking about an actual Attestupan before going to bed, Christian looks over to him asking him if he knows what it is. The duvet on Josh's bed is going over the edge of the bed. Dani then asks "Is it scary", and when the shot cuts back to Josh, the duvet is entirely on the bed. (00:57:10)
Continuity mistake: When Pelle tells everyone tomorrow will be the first of the ceremonies, Christian asks "what's that" after Pelle tells them it will be Attestupan. The time on Christian's watch is around 1:48 when he asks this. Christian then takes out his phone and the time on it is 11:55. (00:56:55)
Continuity mistake: Just after Inga walks out of the main house after first looking at Mark, he turns around to look outside towards her. His left hand is at his side when he turns, but in the next shot, his hand is suddenly touching the back of his trousers. (00:55:05)
Continuity mistake: When Pelle gets his phone to show Dani photos of his commune, Dani stands up from the chair she is sitting on with both her hands at her side. The camera changes to a different angle where she moves over to Pelle's couch and both her hands are more closed together. (00:23:15)
Continuity mistake: When Christian is at the cafe with his friends, just after the waitress takes the tip and Pelle tells him "don't forget about all the Swedish women you can impregnate in June", Christian raises his hands in the air. The shot then cuts to Mark and Christian's hands are suddenly lowered. (00:08:05)
Continuity mistake: Just after Dani re-reads the worrying email from her sister, she takes out her phone and holds it with both hands near the bottom. We are then shown a close-up of the phone and her right hand is now nearer to the top. (00:03:15)
Continuity mistake: When Ingemar is watching Christian's body get engulfed by the fire, he is holding his hands together, with his fingers interlocked with each other in a slightly curved position. The shot then cuts to a different angle where his fingers are more bent. (02:43:20)
Continuity mistake: When the female Hårgas are consoling Dani after she sees Christian having sex with Maja and they begin crying in unison, Dani's hair is tied back, but when it cuts to a different angle, a few strands of hair are suddenly hanging over the side of her head. (02:27:55)
Answer: It's actually a boy named Ruben. It's alluded to him being disfigured due to being the product of incest. In the context of the movie, Ruben is supposed to be an "oracle" who comes up with sacred scriptures, runes, etc. From what I understand, due to his deformities and cognitive disabilities, he's considered to be less "constrained" by typical mental/emotional limitations, and thus more open-minded spiritually. (Basically, they believe that because he's so simple-minded and childlike, he's open-minded enough to able to communicate with higher powers).
