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.
Haha this was hilarious...and this movie was fantastic. Now I'm overloaded with Loki and Frigga feels. Thanks Marvel. I can always count on you to break my heart, and make me love the tortured villains.
