In my opinion, the Loner is a little boy who is quite depressed, probably because of the problems that he's facing. As compared to the rest of the children, he is very dull and lonely. He keep himself a distance away from the other children, and he don't play with them. I think he needs someone to let out his feelings and expressions, and someone to care for him. Maybe he had something hurtful inside him that he has to share his feelings with someone. Unlike the other children, who is very cheerful and happy. Also unlike the beautiful place and cheery surrounding around him.
