Disclaimer: I don't own Thor.
Loki tried his magic to get out of the spell that the frost giant had put on him. However it was very complicated and he had a hard time even sensing where the links of the spell were. The frost giant sure knew his magic. Also after a few moments he noticed the more he used magic the more the spell swelled and the more he couldn't move. The frost giant was smart, which was odd since he had always heard that frost giants were idiots along with being monsters.
While he tried to escape he heard their conversation and had feeling that there was something very obvious that he was missing. It made him feel stupid; he hated the feeling more than just about anything in the world. The frost giant stepped towards him and Thor stepped in the way to protect him. Loki frowned Thor was protecting him from the frost giant even after Loki had just tried to kill him? Then again he supposed that frost giants were something Thor was always willing to kill. Maybe Thor wasn't sure what he was going to do with Loki yet? It seemed impossible that Thor was trying to protect him after Loki had just tried to kill him. Not even Thor was that good of a guy was he?
The frost giant formed an ice knife with a wicked looking edge. It was clear that Loki was the target of the frost giant. He wondered what he had done to the frost giant? Loki would have thought this was about Laufey, about he fact that Loki had killed him. The frost giant however had denied any loyalty to Laufey and had even said that he wanted Laufey dead for what he had done.
There was something...why couldn't he grasp it?! The frost giant phased through Thor. Thor in turn grabbed the frost giant and threw him against the wall with enough force that had the walls hadn't been so strong it probably would have left a hole or sizable dent. However at the same time he knew that Thor hadn't used his full strength. Loki knew his brother-no Thor he reminded himself they weren't brothers- Thor could have threw the frost giant much harder than that.
Why was Thor going easy on the being who intended to kill him? Was Thor not really sure that he wanted to protect Loki after what Loki had done? The frost giant though got back up which was feat which in and of itself. Loki had seen several Asgardians while training receive a similar blow and fall unconscious. The frost giant dodged around Thor; he was fast. Loki might have admired the frost giants fighting style if it wasn't a frost giant and trying to kill him.
The frost giant was quick but thankfully Thor caught up to him and slammed him into another wall and spoke quietly to him. Loki could not hear what Thor said to him or what the frost giant said back. There was something familiar about the frost giant. What was it? Loki wasn't familiar with any jotuns. Had he fought him in Jotenheim? Loki didn't think so, the frost giant was thin much thinner and smaller than all the other frost giants maybe he was a runt? Loki watched the frost giant move he was quick on his feet and seemed to know Thor's battle style
There was something about the frost giant that was so familiar. It was on the tip of his tongue but he couldn't' seem to figure out why the frost giant was so familiar. There was something about him that he knew so well. Suddenly all the pieces of the puzzle just clicked into place. He knew what the frost giant was now and wondered how it was that he hadn't seen it before.
"You're me aren't you?" he said quietly but they heard him. Loki realized that he should have kept his revelation to himself when his other self used the distraction to use a spell to make the walls partially swallow up Thor. His other self turned to him and smiled.
"I was wondering when you would figure it out. Honestly I thought it would be a little sooner even with the Jotun face, but then again if I remember correctly at this point in my life I'm deeply in denial about my heritage. So much so that I thought if I could rid of of Jotenhiem all together then I would finally...fit in? Be free? Belong?" his other self shook his head like he thought the idea was ridiculous. His other self also let go of the Jotun image and Loki found himself staring at... himself. His other self wasn't much older than him. In fact except for being skinner than what was healthy and paler as well he didn't look very different from what he saw when he looked in the mirror.
"Why?" was all he was able to say. Why did his future self want to kill him? Didn't he know that Loki was doing this for their father?
"Because we are a disease and if we are not extinguished now before someone catches us many people are going to die because of us." his other self said stonily but Loki could see that his other self felt strongly about it. What? Only the Jotuns would die because they were monsters and to show father that he was his son. And Thor, Loki glanced at Thor who looked in to be in pain. Thor was still struggling with the wall trying to escape it but no matter how hard Thor fought it he didn't move more than an inch.
"Please I don't understand." Loki said the other Loki looked at him smiled slightly.
"It's okay Loki. I'm not sadistic not anymore and I don't want us to suffer I'll make it quick and painless for you." He looked again at Thor who screamed.
"Loki don't this!" His other self didn't turn to look around at Thor but said in a voice loud enough for both Loki and Thor to hear.
"This is what has to be done."
"Loki no!" Thor said at the same time his other self thrust the ice dagger into his chest.
