They're about the same age here as they are in that little scene at the beginning of Thor. Maybe 5-7-ish?

Thor was getting tall. His height would be great once he was grown.

He disliked the written aspects of his schooling. The martial, however, he enjoyed immensely. He was quick to gather friends from his classes, but it seemed to Frigga that it didn't much matter to him which of those he kept. That they followed him in his wandering did not seem to matter overly to him. He interchanged them frequently.

Loki was his sole constant companion.

Which, to her mind, was as sweet as it could be troubling.

She could not number the times her boys came home, Thor with some scratch and Loki battered because he had had only the determination and not the strength or experience to keep up with his brother.

Thor was but a child, he did not think of such things, and she did not expect it of him. Enough, she thought, that he allowed his little brother leave to accompany him all places.

She spoke to Odin of her concerns. Not only was Thor advanced for his age and Loki's elder, Loki was small and often sick. She feared that his true heritage might yet take its toll on him and she wondered if Eir should be made known of it.

But Odin told her her fears were vain. He would do well. These little sicknesses now would teach him not to succumb to greater ones later. And similarly he spoke of the little boy's challenges. He would be so much the stronger for them once he was grown.

Frigga did not know that she agreed in whole. She tried to interest Loki in other things. And while he'd always enjoyed her company and her tales more than Thor had, such draws could not always keep him penned beside her and out of harm's way.

As much as they loved each other, the boys battled. Many times in a day, Frigga would be interrupted in her work by Thor, shouting, flushed red and gesturing angrily and Loki, crying and shouting back at him. Their nurses were at a loss what to do with them when they fought. They would not be distracted.

Wearily she assured the girls that they had gotten that from their father, and they would smile at her in understanding, remembering their own fathers and brothers.

Loki was more prone to grudges than his brother. Once, Frigga found Thor sitting outside of Loki's closed door, with tears rolling down his cheeks, begging Loki to come out. When she'd opened the door, Loki had been equally distraught, squashed into a corner by his bed, hugging his knees and scowling through his tears at the door.

They were a pair, the two of them. Often she wondered where she would be without her boys, and, in the same breath, where they might be without each other.

If you like things chronological and you've been reading my updates of this and 'Little Lion Man' as I've released them, the first e chapters of 'In the End' would fit in right about here. The next chapter is a bit of a jump in years.
