Season 4 completes new missions as Aethelflaed appears to be preparing for war, and Aethelflaed and Uhtred appear as an ally with Welsh to face Cnut's A-Warrior Army at the Battle of Tettenhall during this period. It seems Aethelred might regret what he did while a prostitute competes for control of Mercia and Edward uses his niece Aelfwynn as a tool in order to do what they want.
Politics, love, laughs, axes flying into faces, characters who can fill your heart with a look, and baddies you're desperate to see punished..., it was all there in episode one. Welcome back, The Last Kingdom, you have been missed.
