Aegelesburg, Mercia; Young Uhtred says a prayer for the lives lost during the Dane attack. Uhtred tells Æthelflæd that they don’t have the time for such luxuries. However, many of the dead are children, which deeply saddens Æthelflæd as she further explains that the Danes also took their heads. Uhtred urges Æthelflæd to leave before the Danes arrive, but it’s too late. Finan and Osferth alert the others that the Danes are charging towards the gate. Uhtred guides Æthelflæd to safety while Aldhelm and Sihtric stay behind with the others to hold off the Danes.
Bjorgulf leads his army into Aegelesburg, killing those who survived the initial attack. He demands that they hand over Æthelflæd. Inside the monastery, young Uhtred, Finan, Sihtric, Osferth, and Aldhelm try to keep the doors shut as the Danes apply force.
Uhtred goes to the roof. Finan and Sihtric follow him with knives held to young Cnut and Esgar’s throats. He tells Bjorgulf to leave or else the children will die. Bjorgulf refuses to leave, and so Uhtred tricks him into thinking that he cut off the head of young Cnut by throwing the body of one of the dead Mercian kids off the roof. In fear that Uhtred will kill Esgar, Bjorgulf retreats.
Cnut will hunt them down the moment he learns they killed his boy. So, Uhtred, young Uhtred, Finan, Osferth, and Sihtric prepare to leave. Young Cnut and Esgar are set free by Sihtric as they have served their purpose. They join Æthelflæd and Aldhelm as they leave for Tettenhall.

East Anglia; Eardwulf informs Æthelred that the settlements around Lindcylne have capitulated. Also, Cnut's armies have raided Mercia and taken the king’s palace at Aegelesburg. Æthelred blames Eardwulf, as it was on his intel that they left Mercia. Eardwulf reveals that he got this information from Hæsten, who the king calls a well known liar. Æthelred fears that his reputation will be ripped to shreds. However, Eardwulf explains that they’ve had word from Lady Æthelflæd. She will be at Tettenhall, where she plans to lure Cnut. There is an advantage in this, so the king can return to Mercia a hero. And so, Æthelred asks if his men can be there by morning. As for Eardwulf, when they return to Aegelesburg, the king will have him publicly castrated. His family will never prosper and his sister will never leave Æthelred’s bed.

Lord Æthelhelm arrives after they have won the battle at Tettenhall. Æthelflæd then thanks Edward for his contribution and for saving her. However, he came against his better judgement, and he doesn’t take his sister’s defiance lightly. He lost many men in the battle, including Steapa. The man they’ve both known since childhood. He blames Steapa’s death on Æthelflæd’s ambition to be loved by all and chronicled for her bravery. He tells her not to return south. Lord Æthelhelm adds that she would not be welcomed by the grieving widows of the Wessex men whose lives were lost. Æthelflæd explains that none of this was done for anything but love of her country. Edward has been made a fool. Unable to even reward his men for their bravery and paying tribute to the Welsh. He intends to make this right.
Uhtred wonders what excuse Edward gave for his cowardice. Æthelflæd explains that he wanted to avoid bloodshed for his men. Which Uhtred argues created more bloodshed. He wants to speak with Edward personally, but Æthelflæd asks him to leave it be and for them to celebrate their victory over the Danes.
