Foster was naive. He had been alone in the 'alley' - an ironic metaphor he used to describe the claustrophobic, four cornered room that was well lit to expose the white walls. After being sedated to sleep for a longer period no one could imagine, he woke up learning he wasn't aging while the people he met was, and the outside world ilwas changing. All he must do to survive is to step up his will to adapt.
