PETER PETTIGREW, OMG. For YEARS I kept saying, 'What are we going to do about Peter Pettigrew?' We must have planned out about a dozen different scenarios for dealing with it, and none of them ever became quite airborne.

Part of the problem, I think, was that we dealt in Year One with the big issue that Rowling dealt with in Year Three: Why are Sirius and Remus estranged? What really happened on that Halloween night all those years ago? I liked our version, but it wasn't infused throughout with the circumstances of Peter's betrayal, so it was difficult to get back to it, somehow.
