A few questions:
-Will we ever find out what others see when they soulgaze Harry?
-Considering how many times Harry has Soulgazed, for the other person looking at him do they each see something different about Harry?
-Is Harry and Michael's relationship inspired by the Merlin/Arthur relationship from the Arthurian Legends?
-what is Little Maggie's official last name? Is it Dresden now?
-will we see more of Little Harry Carpenter?
-Will Justine ever have Thomas's child?
-will any of Harry's friends ever betray him?
-will we ever find out what Margaret LeFae was discussing with Lord Raith, Arianna Ortega , and Ebenezer at that dinner party?
-How much magical potential was Thomas born with? If he wasn't a White Court Vampire could he have become a Wizard?
These are some of the questions I would ask Jim if I got the chance.
