Loki thought of going to his father, was Odin his father, but several points discouraged that idea.
If he wanted me to know he would have told me.
What would he do if he knew I knew?
How would he react to how I found out?
I don't know much and could look like an idiot.
He needed some other way to put this to rest. He wanted to say he was foolish, but it fit so well. It would explain why father/Odin favored Thor. Why would he love a monster? Why would he want anyone to love and respect a monster? Of course he would pick Thor because no one would want a frost giant on the throne of Asgard!
He remembered how he had been drawn to the temple by thinking about the Casket of Ancient Winters. Father/Odin has it. If I touched it surely I would know. I can't let him know I'm there though. He can't know that I know. I don't know how he would react. I'm just another stolen relic. Why did he take me? Who am I really?
I am Loki. I am Loki. I am leaving Asgard so I can live by my own rules. I am not a monster! I am not! Even if…I am.
He steeled himself and breathed in and out. With the ruthless determination that had kept him from breaking at the taunts of the other children after he decided to study magic he locked his emotions away. He activated the illusion and the spell again and then left his chambers. He thought of the weapons room and the enchantment around the destroyer.
If I lift the casket the destroyer will activate surely. I refuse to take such an easy path. I will not let anyone sweep me away with an easy death! "Oh, he was a frost giant and treacherous!" I don't think so. I was loyal to Asgard and I still am. I still love mother/Frigga even if I am wounded by her silence about this. We have grown distant, but she has never treated me as less than Thor. I love Thor still, for when we were children if nothing else. I've just had enough of this realm.
He entered the weapons room and looked for enchantments. Sure enough, the casket had two. One would alert the destroyer if it was picked up. Another would alert father/Odin.
Not today for a few minutes.
Loki braced himself. He grasped the casket but did not lift. He called on his magic in case he wasn't Jotun and the casket reacted negatively because of that. Horror filled him as his magic wasn't needed. He shivered as he turned blue and felt different. He let go of the casket and stepped back.
The god of lies has uncovered the biggest lie of all. How could Odin expect otherwise? He is only Odin now for he was never truly my father. Still, Odin gave me his name. Why ever he did it he did it. I have spent the last thousand years training to be a king and much of that time also protecting Thor. No matter what follows I am still of Asgard: until I choose not to be. Until I choose to leave. Nothing will cast me out. I am Loki and I follow my own rules.
Despite his bravado the shivering continued even after he changed back into his Aesir form.
His Aesir form. Not him, not as he was born anyhow.
It took him what felt like an endless amount of time before he could go back to his chambers.
