Yay for Fancy's return and boots and coat for Helen.
Oh wenches, I so wish you were all watching TLK, it's so good. Anyway, to answer what Erik did, the two Danish warlord brothers Erik and Sigefrid want to capture Wessex from Alfred (The Great) so they kidnap Alfred's daughter Aethelflaed for ransom in order to raise an army. Erik rescues her from rape and they fall for each other. She begs Uhtred to help them to escape, thus saving Wessex from the Danes and her from her brutal husband Aethelred who she married to form an alliance with Mercia. If Uhtred agrees, which he hasn't yet, they will probably have to tell Alfred that Aethelflaed is dead, so he won't be happy, and Sigefrid will no doubt come after his brother for betraying him. I don't see it ending well.
