After seeing various villains being shown in Gotham (Penguin, Victor Zsass, Mr. Freeze, etc.), I have noticed that nothing has been shown about the condition of Jonathan Crane after the events of "The Scarecrow", where a doctor watching over Jonathan has the following conversation with Detective James Gordon:
Gordon: So, he's still in fear?
Doctor: Well, not just fear, detective. Jonathan's brain activity shows he's in a state of intense terror.
Gordon: How long until it goes away?
Doctor: Well, that's the thing, detective; we can't be certain it ever will. (Looks through the glass at Jonathan) Imagine the thing you fear most in the world. Imagine that's all you see, every waking moment.
We are then shown a shot of an evil-looking scarecrow looming over Jonathan as he screams in terror, desperate to escape the terrifying figure. After that, the episode ends, and nothing more is said about Crane.
Does anyone know what happened afterwards, through interviews, or a Gotham-related source, etc.?
