But after the Skarn's attacked. He decided that Sharky's daughter will be a good choice for Next Ruler of Asgard.
After all, Sif is also his own daughter, there is no hesitation in making Sif's daughter the next ruler of Asgard.
And hearing this announcement, the most shocked is Frigga. Although she knew, Thomas and Loki were not suitable for the throne of Asgard.
But hearing that, Sif's daughter is going to become the next ruler. She was most shocked. And she wants to make a plan to ruin this.
Although she did not hate Sif, she even loved Astrid. But giving the throne of Asgard to Sif's daughter was not bearable to her.
Although Sif is the daughter of Odin, she is not Frigga's daughter.
Since she knew the dark history of Odin, and she also knew Sif was the result of Odin and the leader of Valkyrie. She can't accept it.
