Continuity mistake: When the man is teaching the boys how to cut the organs out of the bear, there is a bucket beside the table that is a foot or so away from the man. It cuts to an above shot where the bucket is suddenly right next to him. (02:39:40)
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)
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).
