This isn't Norse mythology. In the comics these characters are actually supposed to be what inspired the creation of Norse mythology but not actually the characters of Norse mythology.Yea, I rewatched as well. The back n forth between them was hilarious. It was weak how they killed off Fenrir though. And in Norse mythology Loki had 3 kids, Jormungandr, Fenrir, and Hel.
In Ragnarok, They act like Loki is oblivious to who they are
