Common name for a group of beasts in Norse mythology, that teamed up with the giants and fought against the gods. The most known are the Midgard serpent, the Fenrir wolf and the Hellhound.
A search for answers brings Magne back to a mysterious woman — and a meaningful mountain. Turid confronts Ran, and former BFFs Gry and Saxa get heated.
Magne continues Isolde's work in investigating the Jutuls and their role in Edda's water pollution problem while learning more about his abilities and evading the increasingly suspicious Jutuls. Magne's mother bonds with Isolde's father, Erik. Magne and the Jutul's son, Fjor, are both romantically interested in Gry, who seems to care about both. On a school trip up the mountains Magne confesses his love for Gry but she chooses to go off with Fjor. After seeing Vidar cutting up raw reindeer meat, Magne realizes that it matches the same blood from Isolde's jacket at the time of her death. Magne then deduces that Vidar was behind Isolde's death all along, and warns him that he will not get away with it. After Magne follows Fjor and Gry, Vidar sends Trym, the hellhound, to kill him. However, Trym proves to be no match for Magne. Gry notices that something is wrong with the Jutul family, including century-old photos and even older artwork showing the Jutuls physically unchanged from the present.

- This is the first episode where the Old World has been mentioned.
- History class, discussing the Norse gods and giants, and Saxa predictably defends the giants being cast as "the bad guys of the story." Then Erik asks if there was something — or someone — the giants feared. Magne raises his hand. Cut to the next scene. The answer is left startlingly obvious for the audience. . . the giants feared Thor, and Magne is the embodiment of Thor. So the giants are afraid of Magne.
