Dead people don't leave notes....We're sure about that? :P
Though I do wonder if Spooky didn't leave would she have been able to act on her feelings?
Being devastated shows how close Spooky and the queen got and whatever Spooky is doing must be fairly important.
I've been wondering, actually, if he got hit by some magic somewhere in his sneaking-about-doing-his-job thing. It'd be fairly ironic that he'd ended up magically invisible and intangible other than leaving notes, after spending so much time behind the scenes making things work...
... and kinda sad, in a way. I'm not sure if I really want to be right, with this idea. :-/
