I like the story line very well, but your grammar needs to be worked on quite a bit; and there are a bit too many asides. Other than that, it's a cute story.
I really like this. If your still looking for a villian name for Jezzie I think Jinx, or Jinxx would be really cute and it would go with the Joker. :D Hope you update soon!
I love this Fan-Fic. :3 You're next chapter should be Bruce's P.O.V or maybe it should be Joker's because he hasn't had one yet. o.o Just write the next chapter, please. :3
