i'm pretty sure anon above is talking about free viking women in their society, since when they raid the monastery the raiders seem v confused as to why there's no women around

one of the viking men tries to rape a briton woman while on a raid and lagertha (ragnar's wife) wrestles him off of her, only to have him try to rape her instead - she kills him there and when they're back she says it's because he tried to rape her, which is corroborated by a couple of people
