Liam’ mum is unquestionably more in need of psychiatric treatment than her son. Whatever pathologies he might have are entirely down to her. He may yet come to the conclusion that her wellspring of kindness (maternal or otherwise) ran dry before he was ever born. On the other hand, older, wiser and kinder heads may be able to help Liam see how he may yet be loved, even though, from their professional perspectives, they could not be the source of it. And so he will remain a sad, sober and isolated young man.
