Lol, in the end the doctor gave up all common sense when it's about the young master XDDD
And gosh, he really has some good parents....they actually waited one year, and afterwards another three years etc for their son to wake up, despite the harsh circumstances o.o According to the doctor, he should have been pretty much dead....not waking up for several months/years; and the parents still kept him in their house while hoping for him to one day open his eyes again o.o ?
