Like I said, I'm 99% sure that I'm rooting for her too. Actually, I have a whole list of reasons as to why:

• BAD THINGS HAPPENED TO ENMA WHEN HE WAS A CHILD
  
• Adelheid is my favorite
  
• Hibari is not my favorite I am sorry to say.
  
• But he would look really hot in chains cough cough ahem oh my what was I saying again?
  
• The Simon family has already lost every single battle they've been in, if you count Aoba vs Ryohei as a loss for both sides, so at this point things are kind of lopsided in favor of the Vongola. And while that would normally be a good thing since the Vongola are our team and all, it still makes things more interesting when they have to work for it a little, you know?
  
• Especially when Hibari "Strongest Guardian of the Vongola" Kyoya has to work for it a little.
  
• If Adel loses Enma will be left all alone with SPADE and KAORU oh my god. THIS CAN'T HAPPEN.

And so on and so forth. Basically I agree with you completely. You also brought up a really good point with this:

And since we seem to be headed towards a prison break, we might as well have a very pissed off Cloud Guardian on the inside to help things along.

Hell yes. That would be both awesome and hilarious, especially since he might end up having to save Mukuro's ass, or vice-versa HA HA I would pay good money to see that. 8D
