It is revealed by the mother that Lukas has died in an accident prior to the events of the movie. She tearfully explains to Elias that Lukas's death was not his fault and she begs her son to set her free so they can both move on from the tragedy. Elias challenges her to prove that she is their mother by telling them what Lukas is doing. As she cannot see the hallucinated Lukas threatening to set fire to a curtain, she cannot answer the question. Elias - believing that his real mother would be able to see Lukas - grabs his arm and lights up the curtain. The mother subsequently burns to death before the firefighters arrive. The film ends with a ghostly shot of the mother reunited with her twin sons at a cornfield near their home.
