Dystopian book inferences

"Ender smiled back. He felt comfortable with Graff. Graff was good."

I know that if you feel more comfortable around someone, you connect better.

Inference is that they form a bond

"Does anyone else have their locker open?" The man looked around. "I mean have you followed directions and coded in your voices and hands"

The guy is obviously upset at everyone except Ender

Inference: Ender is better than everyone else and will be the "choosen one"

Dystopian Prediction

I think that by the end of my book which is "Ender's Game" Ender or Andrew (same person) will be an important part in defeating the buggers who are the enemies on a different planet. Ender in the beginning of the book has his monitor removed which leads him to believe he was out of luck to be special, until a man named graff shows up to his house and tells him having the monitor removed was part of the test and he passed. He has gone further than his two siblings and now he's at a special war camp.
