How does it end?

Anne Marie is dressed as her mother and burns the house down complete with the dolls inside though Catherine lives

It turns out that sadly has Anna Marie inherited her mother Freya's mental illness. I think it was schizofrenia. Anna Marie were the one making all that fuzz over at the island, and she used to go over there and when being there, she "became" her own mother Freya. She used her mothers white dress, and the dolls were her daughters, Ingrid and Anna Marie. Anna Marie was a very sick woman, even though it for a long time looked like it was Ingrid who was the sick one. Ingrid was just quiet and shy, and that caused wiewers to think she was odd and maybe had something to do with the things going on at the island.
Freya was a very sick woman, and the isoand were kept in the family to have a place to put her as her illness slowly increased. Mrs. Linderman were the woman taking care of her, and it was a room in the house on the island where they had to lock Freya in when she got too sick to be free. Mrs. Linderman killes Freya with an overdose sleepingpill, but we never saw that.This was told the wiewers from Mrs. Lindermann.

In the end, Anna Marie is dressed in her mothers white dress and truly believe she is her mother freya. When Catherine comes over to the island, she is trying to ill her, but she end up setting fire to the house. Catherine is rescued, but Anna Marie die in the fire.

I think there were a posibility to rescue her too, but the family doctor was aware of her serious illness, and given the very dark future for her, maybe in a mental hospital, they never tried to rescue her from the fire.

I sailed in the fjord where they were shooting the scenes when Catherine and David were out sailing, and it is wonderful there!!
