Imagine an AU, where Odin does not get to pick which of his sons get to be King. Pretend, whichever one of them wed’s first, gets first dibs. (Since they will already have a Queen, and be on their way to making an heir.)

Odin arranges for a Princess from (insert realm) to come to Asgard; her sole purpose is to meet Prince Thor; in hopes of being wed. Odin is still trying to give Thor the throne, unknown to both Loki and Thor, in the process. The girl likes Thor; she thinks he’s nice and they hit it off beautifully, until Loki comes home. The moment she sees Loki, she cannot help but be smitten with him, completely forgetting about Thor. Loki starts out trying to get her attention as a game. He thinks it would be funny to make the woman Thor was supposed to marry, fall for him instead. Loki plan backfires and he ends up falling in love with the girl, realizing she was actually very smart and nothing like the typical princess that he had met before. Odin finds out and he is less than pleased, even though technically, it shouldn’t matter. Odin tries everything in his power to separate them, including threatening to harm Loki if she doesn’t leave him and marry Thor instead. Frigga finds out about Odin’s threat and helps them escape to elope, knowing that once they are married, Odin can do nothing to change it and Loki will be King; as he rightfully should.

With this ring, I thee wed. I promise to enter a new year with you in January, hold your hands to warm them in February, kiss you under the willow tree in March, take you to Amsterdam in April, watch the sunset with you in May, go to the beach with you in June, prank everyone we know with you in July, watch all your favorite movies in August, dance with you in September, sing you your favorite songs in October, keep you warm in November, and I’ll still love you in December. All year ‘round, all day, and all our lives, I will love, cherish and take care of you. Til death do us part.

His heart beat faster and faster as Daisy’s white face came up to his own. He knew that when he kissed this girl, and forever wed his unutterable visions to her perishable breath, his mind would never romp again like the mind of God. So he waited, listening for a moment longer to the tuning fork that had been struck upon a star. Then he kissed her. At his lips’ touch she blossomed like a flower and the incarnation was complete.
