On an American Horror Story binge (Jessica Lange is a goddamn treasure
and why hadn't I heard of her before) but it's now my headcanon that most of the people at Yamaku died in the incidents relating to their conditions and are ghosts trapped there. Lilly was 'born' blind but stillborn. Misha is alive and unaware of Shizune's demise, whose ghost rejects her affections because of it. Shizune was deafened by a train as it hit her. Emi perished in the car accident. Rin bled out during the surgical removal of her thalidomide arms
(. Hanako died from her burns.
Kenji is alive but doesn't understand the ghostly happenings surrounding the girls which causes his paranoia.
Mutou died, realized it, and never quite made peace with the fact.
Nurse is alive and aware that his patients are ghosts but prefers to let them believe they're alive for their happiness' sake.
