Plan into place

A boy walked with shackles on his arms. He was weak and frail. His amber eyes almost fully closed in pain. This boy was Pidge. He was found by Alkarian people. Taken as he didn't have their abilities. So now he lay in a cell with two boys.
"Hey, kid are you okay?" The soft voice of a boy asked. The 'kid' woke up. Looking into the two boys' amber eyes. One had grey hair and the other a dark chestnut. With a little cough, the other boy replied,
"Indeed. Hey is it just me or is the quality of this cell is inadequate." They boys looked at his intellect in confusion. He looked so, frail and rough that they thought he would have lost all memory.
"Prisoner 11111018 you are one of the luckiest prisoners. Being put into the same 'cell' as these geniuses." It almost made him laugh.
"what's so amusing?" The guard asked.
"Pidge Gunderson. And do you have any other vocabulary that includes eligible words not just simple ones?" He asked laughing. Making both boys in the cell to gasp in shock, and the guard to growl. His eyes turned blood red. Reaching into the cell. Reaching for the prisoners neck.
"Sorry, but you're going to have to be quicker." The strange boy stated as he dodged the attack while twisting the guards arm so he was in pain and pinned him to the cages bars. His eyes returned to yellow. He let go and the guard ran. The youngest boy cleaning the dust off of his hands.

"Katelyn Holt, my mentor has taught me well. Her uniqueness isn't in her moves. It's her strategies and her brains that make her the most unique of us all." He stated. I guess, I guess my sister has grown up. But I saw something in his eyes, a glint of despair, or darkness, heck it could be sorrow. A single tear escaped,
"I left the night she went missing. My mentor, missing." My little sister, gone. I sat in the corner. Eyes welling up with tears. My little sister, the only person I loved as much as I can (only a little more than my parents). She. Was. Was...
