Answer:
Two voices are discussing Ender's incident on the flight. Graff seems to be one of the two, since the other commends him for allowing such a thing as a broken arm, even though Graff insists that it was an accident--it was too strong a reaction, and it made the other kid into a hero. Ender might be too isolated now. But they realize that they can do little for him, because if Ender comes to believe that anyone will ever help him out, he's "wrecked." Ender needs to know that there will never be an "easy way out," or else he will not become the commander they need for the upcoming war.
The boys arrive at Battle School, and Ender comes in last, so he gets the bottom bunk next to the door. He follows some directions on paper in order to activate his locker and "desk" (some kind of computer). Ender's locker includes the desk, outfits, and some kind of laser gun for freezing others during the battle games.
The boys are given an orientation, and a man named Dap says that he is the only person at the school who is paid to be nice to them. Dap warns them against fighting and the prospect of being "iced," that is, killed or sent home.
