In the time of King Alfred (David Dawson), his wife held a very special place in court. Her word was almost as important as her husband’s and she wielded a lot of influence with everyone. Now that Alfred is gone, Aelswith’s son, King Edward (Timothy Innes) is head of Wessex. She finds her son doesn’t need her as much as she’d hoped. Instead, he’s relying on advice from others, including his wife’s father, Aethelhelm (Adrian Schiller).

Why Lady Aelswith has a change of heart

Aelswith quickly realizes that her efforts to make Wessex great aren’t appreciated by her son. She’s being moved to worse rooms and being treated with less respect than ever before. She starts to regret her past choices and the way she chose to treat some people, including Father Beocca (Ian Hart), although she isn’t able to stop him from going off with Uhtred (Alexander Dreymon).

She helps stop the Danes by defying her son and king

When Aelswith’s homeland of Mercia is attacked by the Danes, she strongly encourages her son to come to their aid. Her own daughter is the Lady of the Mercians and she chooses to go off and rally the men to fight. Aelswith keeps this a secret and doesn’t tell her son until he confronts her about it. When her good advice isn’t taken by her son, she defies him by sending Father Pyrlig (Cavan Clerkin) to the Welsh to get them to join the fight.

With the Welsh backing the Mercians, they win the fight when Edward decides to join the battle once it’s already begun. In the end, he seems to have taken his mother’s advice and helped his sister and fellow countrymen.

Aelswith even reunites Edward’s first wife with her son Aethelstan

Aelswith is redeeming herself all over the place in season 4. She arranges a meeting between Edward’s first wife with her son, Aethelstan, who she hasn’t seen in years. Aelswith tells her they can never see each other again, but she’ll keep a watchful eye on the child. She knows that the reason they are separated is because of her doing when she urged Edward to marry another noblewoman instead, something she’s come to truly regret.

Lady Aelswith has had a change of heart and she realizes she can no longer act the way she used to. She must conform to this new way of life to survive, but she’ll also try to do the right thing along the way.
