Imagine Odin really is Loki’s father, but Loki’s mother is Laufey and all those stories you hear about the war with the frost giants leave out the more scandalous details. Once unleashed in Asgard, Laufey accuses Frigga of kidnapping. Frigga accuses Laufey of abandonment. They wake up Odin with their arguing and both lay into him for two-timing. Plus everybody is mad at Loki for trying to set up an interparental assassination. Odin wants him imprisoned for treason, but Laufey wants to take Loki back to Jotunheim for a proper frost giant upbringing. Loki says he’d prefer banishment to Midgard. So Thor and company return not to combat and imminent planetary destruction but to a humdinger of a family row.
