Bobby was also lost in his own thoughts, trying to separate what he remembered from what he'd been fed the last fifteen years or more. Neither of his grandfathers liked his dad, for whatever reason. Even his mother had little good to say about Jack. Bobby had, effectively, grown up without a father.
