Time skip- 10 years. Thor: 22 years old, Loki: 24 years old.
Thor has prepared for this moment for two weeks. Today was the day when he would be officially the King of Asgard, the Allfather. Today was the day he has been waiting since he was ten years old, since the day he was told that when he would grow up either him or his brother, Loki, will possess the throne, the all power of Asgard and the world will obey in front of one of them.
It will be me- that's what Thor said when he was told that story -
I will be the King of Asgard; me, son of Odin. When he finally took Mjolnir in his hands and prepared to enter in the feast room where every single human of Asgard will be there, hearing him making the oaths.
"They will be there. My brother will be there to see my victory and my father will be there to name me the King. To give me all the power."
He inhale the gaze from the room of Asgard and he could have imagined how the feast room will look: all the population of Asgard adjusted in the sign of Asgard, the throne and in front of it his father, in the left his brother wishing him a fake "I am proud of you" and his mother being there, dressed in a beautiful gallant dress and in the right his friends who have always been there for him.
"They will all be there"- he said looking at the guardian who was faking a smile, but Thor was too happy and excited to say something bad.
Not today. Thor entered the room, being so nervous, but when he saw the people in there looking at him and, more exactly, waiting for him to come, he just smiled and lifted Mjolnir, receiving all the claps and the shouts.
He did this and felt so glad to hear that the people loved him as a King.
"Yes!" - he shouted and smiled in left and right so that all the people from Asgard can see him.
This is my moment of glory. This is my moment of victory. My moment being the King of Asgard. My first moment.
