Varför får Bean hemma om han inte har ett hem?

I Ender's Game (i slutet av kapitel 12):

Bean wondered about it as he walked back down the corridor to his own bed. The lights went out just as he reached his bunk. He undressed in darkness, fumbling to put his clothing in a locker he couldn't see. He felt terrible. At first he thought he felt bad because he was afraid of leading an army, but it wasn't true. He knew he'd make a good commander. He felt himself wanting to cry. He hadn't cried since the first few days of homesickness after he got here. He tried to put a name on the feeling that put a lump in his throat and made him sob silently, however much he tried to hold it down. He bit down on his hand ta stop the feeling, to replace it with pain. It didn't help. He would never see Ender again.

Problemet med detta är att i Ender's Shadow framgår att Bean växte upp hemlösa på Rotterdamens gator. Ingen indikation på att han någonsin kände det som någon känsla av ett hem eller att han ångrade att han lämnade där. Till exempel läs kontot för Beans första natt på Battle School:

Bean slept lightly, listening, as he always did, waking twice that he remembered. He didn't get up, just lay there listening to the breathing of the others. Both times, there was a little whispering somewhere in the room. Always children's voices, no urgency about them, but the sound was enough to rouse Bean and kindle his attention, just for a moment till he was sure there was no danger.

Så varför skulle Ender's Game ha sagt att han grät hemhjälp?
