I feel like I'm going to run out of compliments to give you very soon... so I'll stick with "just awesome". I don't know if I've mentioned this, but you've written pretty much exactly the kind of werewolf story that I really enjoy - and TG into the bargain, icing on the cake! Or should that be the other way around - a TG story with werewolf icing?
Either way, I think that in the next chapter, some explanations are due... this random shifting for seemingly no reason can't go on forever, after all.
