"Nott's parents are both deceased. I don't know who else he has - if the hospital hasn't found anyone, it's likely they don't exist, or they're not interested." Severus thought that a team from St. Mungo's was probably a better custodial candidate than Gregory Goyle. Why was he so distressed? "If you feel he's being mistreated, there may be other ways to have him released - moved, at least. Is that why you think he needs you? What are you going to do for him? You're not a healer." Severus had never noticed that they had been friends. They seemed a strange pair.
