Ho. 
This is Bean. I'm thirteen. Yes, that Bean. Strange name, I know I know. But it was given to me by the first person to ever care for my existence, so I use it. 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
"You ain't worth a bean."
"Am too."
"Yea. One damn bean."

My true name is Julian Delphinki, but my embryo was stolen by a crazy scientist, and he gave me Aton's key. 
A genetic defect. 
There were others like me, but he killed them. I escaped to the streets, where lived till I was four. There I was named by Poke, who was later killed by my worst enemy, Achilles. He would have killed me too, if not for Sister Carlotta. 

She took me from the streets, and realized I was a genius. She got me up to battle school, where I quickly hacked my way into the system. I was the brightest kid there, but I lacked the qualities of a leader. 

But Ender didn't. Ender, my best friend, my idol. He is the best. I am his second, I am there for him if he fails.

"I need you to be clever, Bean. I need you to think of solutions to problems we haven't seen yet. I want you to try things no one has tried because they're absolutely stupid."
