You set his mind on fire
~For the NBC Hannibal fan art contest~
Hannibal was responsible for Will’s encephalitis going as far as it did. (( “setting his mind on fire” and the example of this being the drawing of the clock and his head ablaze. )) Hannibal framed him for the murders (( by tampering with his fishing gear and making him swallow Abigail’s ear. )) Then Will was sent to the Baltimore state hospital for the criminally insane, so he is wearing the straightjacket and muzzle.
