The Last Kingdom: 10 Things That Must Happen In Season 4

Aethelflaed the warrior queen of Mercia is a fearless and daring leader in total contrast to her spineless husband Aethelred. Her decision to ride into battle at the head of the Mercian army during the Season 3 finale really turned the tide in favour of a crucial Saxon victory. The daughter of Alfred The Great will become a key player in Season 4. Millie Brady (on the back of a standout performance) has recently been cast in the upcoming Witcher series which will also air on Netflix.

Aethelred's scheming and plotting has earned the hatred of many fans - especially his failed attempt to assassinate his wife. Aethelflaed must commit regicide and take her rightful place as leader of Mercia with Aldhelm as her faithful lieutenant. This will also create an interesting storyline as Aethelflaed will surely face challenges from a Saxon society dominated by men. Will we also see the birth of Aethelflaed's daughter Aelfwynn?

Her flirtations with the serial womaniser Uhtred and their obvious feelings for each other have strongly hinted that they will become lovers in Season 4. Aetheflaed's shrewd political mind ensures that she is more than a match for Uhtred's wayward nature. There is a real onscreen chemistry and they evidently share mutual respect and affection.
