Quite the deft blend of two different genres. I suspect Hermione was giving Harry an update on just who was after "Jason". From the snippets in this chapter, I suspect it might be easier to say what organization isn't after him (besides ones like $-H and FFA, of course). I do like the way both he and Harry are trading help and information; this story is developing quite splendidly.

They traded some information but not too much as they didn't fully trust each other. I decided that it would be more interesting if Jason had to figure out the magical world on his own without help from Harry.
