It really does seem like you just have to click in a different mindset when you're trying to write Joker fic.
Definitely. I really didn't realize (or at least care) until after I finished that I felt any different -- I think the act of getting into his head is just so insanely fun you don't really notice there's something wrong with it until you pull away.

And gah, thank you so much! I am a bit stunned by the response and your comment makes me all fuzzy inside. :) *hugs*
