Since Eadith and her brother’s family are in disgrace, they both want to better their position. That’s why Eadith goes along when her brother convinces her to be by Aethelred’s (Toby Regbo) side and eventually sleep with him. Eardwulf doesn’t care who he has to hurt, including his sister, to get back on top. He’ll tell any lie and kill whoever he has to in order to secure his position.

Aethelred sustains a serious head wound in battle and it’s only a matter of time before he dies. Everyone in Mercia is trying to decide on a successor, and eventually Eardwulf is chosen as the contender. He goes to Aethelred to tell him, since he’s going to marry Aethelflaed’s daughter to secure the situation. Aethelred isn’t having it though and he doesn’t want it to happen. Eardwulf gets mad and tightens the bandages around Aethelred’s head until it kills him.

Eadith watches it all go down, and this isn’t the first time that she’s seen her brother kill someone. Aethelred is dead and it seems like Eardwulf is going to be the successor. He has Aethelflaed locked away at King Edward’s (Timothy Innes) request. Eadith has had enough and she finally takes matters into her own hands.

When no one is looking, she lets Aethelflaed escape and she aids her in the process. She alerts Aldhelm (James Northcote) to come to Aethelflaed’s assistance. Aethelflaed of course thinks it’s a trap, since she regards Eadith as her husband’s mistress and nothing more.

“Why would a mistress help a wife?” Aethelflaed inquires.

“Because Mercia has wronged us both and our brothers have turned on us,” Eadith says. “Lady we are not so different. I never humped Aethelred willingly and believe me, I am paying for it.”

Eadith tells Aethelflaed that her brother can’t be trusted and “will bring disaster.” Aethelflaed decides to trust Eadith and tells her to find Uhtred (Alexander Dreymon) and tell him to meet her somewhere. Aethelflaed ensures her that she will never go without money if she helps her.

Why does Eadith help Aethelflaed?

Eadith knows that her brother is an evil man. She’s seen him kill more than once and she wants no part in it anymore. She sees a common struggle in Aethelflaed, as they are both women trying to deal with the backwards political landscape that they find themselves in. They are both victims of other’s ambitions in many ways. Eadith chooses to help Aethelflaed and it changes her life.

In the end, fans see Eadith’s redemption in The Last Kingdom after witnessing her brother’s evil deeds.
