Nice, they are getting allies at Hogwarts which should help as matters get more involved. I do think Oswain is right, I suspect that he would like to get caught and force Edward to tell what really happened that night (so far, it sounds like the five of them were attacked and Edward did a "bugout" instead of staying and defending/assisting his siblings - the true story of that night will make a fascinating read when it comes out). I can't help but wonder just how much Hogwarts will be able to help them improve and expand the map, that may be a deciding factor.

(rubs hands)Oh, Hogwarts is going to help a lot. But she'll still need help in getting herself ready. I believe the chapters should start picking up in the next two or so.
I really want to get to November 25. :D
