Alfred will need to make a decision when Heahmund returns with Lagertha and Bjorn. "Murder Most Foul" is the twelfth episode of the series' fifth season.
Torvi and Bjorn might be over, but she's still a fierce warrior who will fight by his and Lagertha's side against Ivar. She'll protect her home and children at all costs.
Whatever Lagertha and Bjorn were talking about, Bjorn doesn't appear to like what he's heard. He has his back turned to his mother. Will he stand by her side or continue his exploration?
