While Geser is fixing him after the fight with the two vampires we learn the story of a young woman, who had a curse placed on her by a witch. Any house she entered the pets died, any animal she petted died and she basically cursed anyone or anything she touched. In short this blond doctor is a present day version of her.
Geser provide Anton with Olga the owl, she in facts turns out to be a woman who was cursed to be an owl as a punishment after disobeying Geser. The pair of them are then sent to protect the young boy from earlier, Igor. While looking after him in his flat Anton discovers from a photograph that Igor is in fact his son and was the son that he tried to kill earlier in the film. He also learns that Igor is an other and briefly explains to him about each side and that in the Future he will have to choose a side, but it is his choice alone.
Anton gets called away to try and find out who cursed the doctor as the foreseen tornado steadily approaches Moscow and starts to cause chaos. Understandably they do not want Moscow to be destroyed so they send Anton to try and get the Doctor to confess as to who cursed her. After tricking her into letting him into her flat we learn that she is an other who cursed herself. Anton gets her to uncurse herself and the tornado disbands into a flock or ravens.
