I like the premise, but when is he getting out of the hospital, sorry but i only have watched 2 chapters of greys anatomy and i dont know the characters :C
while I love the music aspect.Genious level intellect is what would have made the story intresting and it could open up many opportunities for the progression of the story.
Do not change the story that only helps lexie because she is his half sister. But the rest of the characters were forged by the events that happened to them. And I watched up to season 13 so
