After reading the whole series prior to Peace Talks and Battle Ground coming out several things have popped up and I would like to see what everyone's thoughts are on them, here we  go:
1. Several times in Battlefront Harry hears commands from both Molly and Mab in his head, since he is the winter knight and Mab is his liege lord, does she have a connection with him where she know what is going on with him?  It seems like going back to CD and SG that she knew more than she was told and I believe she has a contact with him similar to what Harry has to his supporters thru the Banner.  The reason i bring this up is her quick comments to Harry in Peace Talks about not bringing her name shame if he screws up the rescue of Thomas, it is like she knew what he was doing.
2. This is a big one, why does Mab want a better relationship with the White Court?  This one just doesn't seem to work out in everything that we have read to this point, unless Mab is grooming Lara for a Winter Lady position? or she knows that Lord Wraith is "N"infected and wants a closer look? We know from previous books that Mab always has several moves going at any time due to her responsibility of protecting the outer gates, so either is possible?
3. The last three books Mab has gotten way to close to the Baron of Chicago and I have thought that this was weird, until we find out that Marcone has a coin.  I believe that she knows this and is keeping her enemies close, and she still has payback to Namshield for attaching her home.  I thought Namshield was "N"infected, so now i wonder if Marcone is too?

So does this mean that there will be 22 files, then the final trilogy?

I have a theory that Harry has never meet the real DuMorne!  That the person that came to fetch him was a Black Council member and that he knew about Harry because he was friends with Maggie Sr. and her crazy crowd.
