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.

A humiliating conversation with his brother forces Leif to reconsider his leadership style. Teo puts both himself and the clinic at risk by seeking out his wife, Marit. A patient gives Ravn an idea that could help Vilma. But before he can give Vilma a new drug, he needs a test subject. Someone expendable.
