Quote #10
I half expected someone to be home. As far as I knew, Isaac had lived by himself. But you never know. (10.19)
Leo's image of his son is, in many ways, of a man utterly different from himself. So he can't help but imagine that, in contrast to his own loneliness, Isaac would share his home with someone else. The line "you never know" reminds us of the privacy that only the home provides.
