It's his only home.
That's sort of what I mean, as in...Does David really feel that Collinwood is his home? More so than the Augusta home? What is his feeling for Collinwood besides that?
Emphasis on "only". He doesn't have to have any feeling whatsoever for Collinwood, not to want to be sent to juvenile hall, a psychiatric ward, an orphans' home (he thinks that's possible), military school, wherever. I don't think his going back to live in Augusta is an option, and even if Roger owns that house there, David and Roger alone in that place would be a nightmare. At least at Collinwood he has a couple of more pleasant and protective relatives, a mansion to live in, good food, and toys, and some privacy.
