Frigga is the Queen of Asgard and wife of Odin, mother of Thor, adoptive mother of Loki, and adoptive grandmother of Sophia, Lily, Jane, and Renesmee. She attempted to keep the peace between the family even when Loki discovered he was the true son of Laufey and became vengeful towards her and her husband. Frigga was distraught after her youngest son ran away from Asgard, but understood his reasoning.
When Loki returned with two people that he introduced as his boyfriend and daughter, Frigga was ecstatic to meet her first granddaughter; while her husband and elder son were respectively in states of disbelief and outrage.
