"Thor, get out of my room!"
"Come on Loki. I'm bored," Thor pouted a little.
"Then go being bored somewhere else," Loki shot back and shut the door right into Thor's face.
There was silence for a while and Loki thought Thor went away; but then a muffled voice came from the other side of the door.
"Will you come out?"
"No."
"Why not?" Thor's voice was curious and demanding at the same time.
"Because I don't like you."
There was a short silence again.
"What are you even doing?"
"It's none of your business," Loki didn't sound as irritated as before. From his voice Thor presumed that his thoughts were captured in something that held all of his attention.
And he was right. Loki was reading some sort of magic book Frigga gave him. Lately that was all he did. He was just starting to learn simple tricks and spells and he only came out of his room for food or more books.
"Loki, you know what?!" Thor shouted with stupidly happy excitement that he was able of from birth. That excitement irritated Loki almost as much as his haughtiness.
"What?" Loki sight, half angry, half bored.
"I thought of a game. I know that you're doing some freakish-eerie-spooky magic stuff in there, so we will play a magic game."
Loki didn't answer.
"And you will get to stab me."
A moment passed but then the door opened and Loki stuck his head out.
"I'm listening."
After some explaining and a lot of negotiations that weren't exactly peaceful or couth, the rules had looked something like this:
They would play an advance version of Tag, you're it. Loki wasn't really a runner so he would try to sneak on Thor and stab him. He could use any form of transforming magic or simple cloaking tricks. When he succeeded it would be Thor's turn. Of course Thor wouldn't stab Loki (knifes were way too sharp and pointy for his liking), so he decided that when his turn came, he would try to give Loki a hug. Let's just say that Loki agreed to that rule only because he would still get to stab someone.
So it began. The game was on.
