Loki and Frigga --- you cannot doubt that Loki loved Frigga, and that she loved him. Loki learned all his tricks from her. She spent time with him. Unlike Odin, Frigga didn't care about blood. Loki was just as much her son as Thor was.
Tom Hiddleston talks about Loki's relationship with Frigga. Loki and Frigga are both adopted in a sense. Frigga is Odin's 2nd wife and not Thor's biological mom. <<<< why didn't you tell me this; where do you know this from?!
