Ravn is clutching at straws, searching for something that can help Vilma. Research was her domain, not his. Against Leif's will, Ravn decides to let Vilma's research colleague Unn, in on the secret. Teo, trapped underground and separated from his heavily pregnant wife Marit, is almost driven out of his mind. He dreams of building a shelter for himself and his family. And Leif is keen to help. This, however, requires serious resources, and so Leif begins to make demands of Ravn and Unn.
