More myth characters!
Love this show. They should include some more mythic characters other than Eris and Grim. I think Loki would be cool in one or two episodes; having a strife with Eris even though they're in different canons. Maybe Kali? Could be scary for the kids unless they make her somewhere PG.
Just had this idea since I like myths and mythic characters interacting with the modern characters. (BTW, I just finished reading "American Gods," which influenced this thread...)
