I just wanted to clarify on Kari's age and how it all works out. Approximately 62 earth years is one year for an Asgardian. Hella would have been around 48 in Thor Ragnarök. Hella would have been around 32 when she was imprisoned. Since Kari was around 14, she would have been 868. Kari would currently be around 1,860 if I calculated that correctly. That is around 30. Thor is around 24 and Loki would be around 22 because I heard somewhere that frost giants age slightly faster than your average Asgardian. So I hope that clears some stuff up.
Also one last thing: What should Tony nickname Kari? I want something that sounds like Tony would say, but I've got nothing momentarily. Thanks. I will let you get back to the story.
