Excellent update, though I'm frankly fed up with Remus/Tonks. It isn't a sensible enough pairing to just throw them together as an afterthought like that, so unless you're going to take the time to develop them into a real relationship (for my satisfaction, it has to be done far better than JKR managed), then don't even bother with them. There are less cliche ways of making the pair of them happy.
Looking forward to more, in spite of what my negativity might lead you to believe.
