Mama Frigga and her baby boy *gif*, I love how much of a mother she is to him even though she knows he's not really hers, she's so wonderfully kind and Loki does love her as his mommy its a cute relationship :)
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.
