"Brothers shall fight and slay each other," sang Knut. "Garm howls in Hel, and the wolf runs free."
It's late Winter, and Robin's still isn't used to Asgard.
Last year she left Valhalla without permission. "I don't want to fight and die at Ragnarok," she told her new friends. "I want to win!" Every day, they swore their oath on her magic sword Frostbite, even the snarky squirrel Ratatosk. "All for one, and one for all."
Now her magic sword Frostbite has turned into handsome Frost Lokison, and they're living together, and someday soon they're going to get married. The really unsettling change is that Robin and Frost have dinner once a week with his parents.

Loki thinks they'll need his help
