So we all know the story. Odin sets out to kill himself some frost giants and, along the way, finds one of his very own, conveniently in non-blue packaging. He takes the baby back to Asgard and convinces his wife that they should adopt him. Further, they decide to not tell anyone the baby is a frost giant, because “no one likes frost giants and let’s give this kid a break” (I may be paraphrasing). Okay, so then what? How did Odin and Frigga convince an entire planet that Loki was naturally conceived and born from the royal couple?
I don’t think they did. At least not with the Asgardians who were adults, living in or around the palace at the time. Let’s look at the options.
