Frigga and Loki
Frigga smiled then. He had a better outlook on it than most would have had. "Dare I say you've become optimistic?" She teased lightly. "Not that I think you couldn't beat her if the playing field were even. If she could have no hold over you. But that is her domain. She would use you up, and then use you again. And would not be sated." No it was not worth the risk. Even if both her sons together could beat Hela once and for all. They had other things to think of. Life beyond war and domination. Both of them had families, Loki and extended one, Thor the start of one. That was enough to sate her. For now.
