All credit goes to their respective people, A.K.A. Marvel because sadly I don't own the movies, let alone the characters.
From the moment he arrived, they knew something was wrong. He was much too small, much too pale. Both Laufey and Fárbauti agreed, he must be sent away. In a land where snow, ice, and war pillaged the land, no child, Jötunn or not, could survive that small in a world so vicious. The babe would have be taken to the temple and placed on the large steps. His fate would've be given to a being much mightier than himself. Laufey had only decided against this very action because of the royal blood running through the child's blood. No child of his would end up a mere servant, runt or not. The child would be sent to live with the nomadic Jötunn currently residing in the area. Their child would not know of his true family for his heritage marks were incredible light, almost unnoticeable. Then again, with the young one's size, there was very little chance that he would survive more than just a few more years.
Thor, however, had different plans. Even then he was racing through the palace halls, aiming for his Dam's room. He had heard that Fárbauti had gone into labor and was excited to see his new sibling. Past soldiers and past servant he ran, bumping into quite a few, barely refraining from toppling others. His cheeks shone purple as he halted in from of his Dam's door. He took in a deep breath and desperately tried to straighten out his appearance. He tugged his fingers through his white hair and worked to untangle it from his two, small, slightly curved golden horns. He fought to unknot the strings of crimson jewels strung throughout his hair. Some were tugged free and dropped to the floor. He reached down for the and stuffed them in the pouch hung along side his loin cloth. This and a pair of leather moccasins were the only clothing he wore for the Jotunheim weather did not harm to his thick skin air in the palace, where no windows littered the halls or the rooms.
He gently rapped on the door, waited for a moment before doing it again. When neither his Dam nor his Sire answered the door, he let himself in. Expecting to see his new younger sibling, he was surprised to see the room empty. He stood there for a second, looking for any sign that his parents had been in the room. He had thought that perhaps they had already moved the babe and moved to leave the room once more. As he reached for the door knob, he heard harsh whispering coming from the conjoining room. He stepped away from the door and slowly walked towards the sounds. As he came closer, the whispering grew louder. He caught bits and pieces, " too small..." " what will we do?" Thor took another step closer, willing his ears to hear the words spoken. "Send him away."
"No!" Thor burst into the room yelling at the top of his lungs. Both Laufey and Fárbauti looked at their third child surprised. Laufey stepped towards Thor and said angrily, "Leave immediately. You have no place in this conversation." Thor looked at his Sire, scrunched up his face and began to cry. Tears rolled down his cheeks and he hiccupped as he sobs, "You can't send my little brother away!" Laufey sighed and bent down on one knee, wiping the tears from Thor's cheeks. "Thor," he began in a calm voice, "your new little brother is very different from the rest of your brothers." He placed his other hand on Thor's shoulder, beckoning him to rise. "He is only about half the size of a healthy Jötunn babe. He is what we call," He paused for a moment and moved over to the large crib against the wall. "He is what we would generally refer to as a 'runt', Thor" Laufey bent down and lifted up the babe, holding him close against his chest.
Thor looked thoughtful for a moment then looked up at his Sire and asked, "Why have I never heard or seen any 'runts' before then?" Laufey gave his son a gentle smile and replied, "Normally they are sent to the temple, where they will live out their short lives in servitude to the realm." Thor looked up at his sire holding his new little brother. He could not quite understand why his sire wanted to send him away. He loved his new brother. He reached out and grabbed a hold of his father's black cloak and gave it a tug. His sire looked down at him questioningly. Thor swallowed and after a moment, asked, "May I hold him, sire? Please?" After a second of hesitation, Laufey leaned down enough for Thor to reach and take his brother from his arms. Gently Thor cradled him, staring down into the light pink eyes twinkling back up at him. As his brother aged, his eyes would gradually darken to crimson but for now, they would remain a soft pink. Thor shuffled him into one of his elbows, freeing his right arm. He reached down and gently caressed his brother's cheek. Small nubby fingers reached out and grabbed one of Thor's fingers. In comparison, his fingers could barely grip the complete width of Thor's finger. His arms tightened around him and he clenched his jaw. Staring up at his Sire, he spoke up, "I want to go with him."
"No!", his Dam screeched from where he was reclining against the wall. "My son, you cannot!" He had stood to his complete height, about two feet shorter than his spouse. He walked up to Thor and looked down at him, "Your place is here while that thing," he said with a sneer, "belongs elsewhere." Thor cowered, his brother held tight against his chest. From the bundle he had clenched came a loud cry. Fárbauti seemed to jump, surprised from the loud sound. He looked as if he had thought the babe had been some weak little thing incapable of any sound, loud or not.
"F-fine! Take him then!" Fárbauti said, anger in his voice, "But know that the moment you leave with that babe, you are no longer a part of us." He ended his words with a deep glare at Thor, or perhaps instead at the bundle wiggling against him, still crying. Thor reached down and hushed and cooed at the babe till he settled down. He looked up at him Dam and replied, "I understand. For I cannot just leave him alone in a world pitted against him." And so he left the room, and within the day, the palace, leaving behind any form of family he had known. But it only took one look from the babe wrapped in fur in his arms to melt his heart. About half an hour after leaving the palace did he realize his grave error. They had not yet told him his brother's name. He looked back at the palace in the distance. He could not go back or he would not be able to leave again. No, instead he reached and cupped the babe's cheek. "Loki," he whispered. Loki giggled and rubbed his cheek against Thor's hands. He smiled and kept walking.
