Margrethe wants him to claim the throne himself and questions the queen's strength, drawing a warning from Lagertha. Elsewhere, Astrid agrees to marry Harald. Floki decides that the land he has found should be shared with other believers and prepares to bring people there, turning his solitary journey into a plan for a settlement.
