Loki opened the door to a slightly sickly looking woman in a green tweet suit skirt. Although the petite human was so much shorter than his Asgardian height, Loki found it amazing that she could look down her bespectacled nose at him. Amazing in an annoying sort of way.
Loki looked at her expectantly as the green woman took his wet state in. He shifted his daughter from one arm to another as he decided prying his son off of his leg wouldn't prove productive.
"Is there a problem with having soap bubbles on ones shirt?" He asked, looking at the woman.
"Of course not, Loki—" she raised her eyebrows at this, as if to say she knew he would be a failure of a dad simply by his odd choice of names. "Odenson. I'm here to discuss Sven's classroom behavior." She looked at the child anchored to Loki's leg. "Sven. Your… son." She added for clarification. Loki internally scoffed. As if he didn't know Child Number One's name. He briefly contemplated turning the woman into a frog. She would look good as a frog.
"You are going to let me in." It was a statement. Loki really didn't like it when humans gave him statements. He could already feel the magic being drawn from his heart, down the arm that wasn't holding his daughter, and pooling in the palm of his hand. One human into a frog. Nobody would miss her.
"Loki. I'm afraid your child is very incompetent. He—" pop!
He smirked as the yellow sparks faded from his fingertips.
"Take the frog out to the pond, son. I'll make some sandwiches for lunch." He bent down to look Sven in the eye, making his daughter giggle a little. "And no telling Mummy, eh? What she doesn't know can't hurt her." Sven grinned and bounded off with the frog.
"Come on Ducky," Loki said to his daughter, "Let go make lunch."
Later on in life, Loki would determine it was turning the women into the frog that started all the trouble. How could he have known she was a sprite? He dimly noted during the transformation that it took less magic than he thought it would, but he hadn't deemed it truly important. Magical creatures took less magic to change, as it was already a part of their blood. Later he would also think back to how the woman—or sprite—hadn't given him her name, nor stepped over the threshold uninvited. Classical signs of Midgardian creatures with magic. If only he had noticed.
