I'm going to stay at Malfoy Manor this weekend and assess the situation. See what his family are like towards him. I think he's just overreacting - as usual.
Might just rip the band-aid off for him and tell his folks. Would that just be cruel? Or would it be more of a cruel-to-be-kind situation? I don't know. Living a lie surely isn't good, and his parents aren't that bad. They probably wouldn't kill him or anything.
