I'm so sorry it's taken me so long to get back to comment on the end of this story! Gah. I've read and reread it a few times this month, actually. Heh. It's definitely going down in my favourites folder for PWP fic; that's never been debated. :) But as Maggie mentioned (and omg your comments here are so fascinating to read!), there's a lot more to this story than PWP. It does straddle (cough *is twelve*) both story genres, the PWP and the longer drama.
And I've been thinking A LOT about this story. Please don't take it as criticism; I just want to think out loud here for a second, which I will then (hopefully) wrap up in a coherent conclusion about how much I liked it. Okay, at first, I thought, Hmmmm, nooo, this has missed a fundamental element of a long story, which is a late-act conflict of some sort to be resolved in order to achieve denouement and resolution in the final act. And (as you can tell from my comments along the way) I was utterly convinced, from the beginning of the story, really, that the coming conflict would be someone finding out about Remus and Teddy's relationship.
And so, armed with that expectation, it was somewhat jarring at first to realise that wasn't going to happen.
BUT, the more I've thought about it, I'm not disappointed anymore. Because I've thought about what I would have done as a writer, if this were my story -- how would I have managed that sort of conflict scene, with Sam, Andrew or someone else discovering the secret? What would I have done? And tbh, I HAVE NO CLUE. :/ It's not possible, I now see. There is NO WAY that, within the marvellous universe you've created here, someone could have found them out and the entire fic would not have disintegrated in a hellfire of angst and doom. You know? It would have completely changed the story. Within this universe, again, I stress -- it might have had a different outcome with different characters -- the only way to have Sam or Andrew find out, and keep everyone IC, would have been for them to end their relationships. Neither of them could ever have forgiven Remus and Teddy for this; the relationships would have died completely. And then where does that leave your story?!?!
I see all of that quite clearly now. :)
So, realising all of that also made me rethink the central conflict of the story. Where is it, then, if not external such as a discovery scene? It's internal, is where it is, and whether you meant to or not (I mean, obv you did mean to!), the story is so lovely and nuanced and quietly brilliant for that. What I'm saying is, the conflict I was anticipating for around Chapter 16-19ish? HAS BEEN THERE ALL ALONG, LEE, YOU IDIOT. :) Every time Remus closed his eyes and berated himself, feeling tortured for his desires, was that conflict in action. Every time Teddy lied to Andrew about Remus, was that conflict in action. Every time Remus and Teddy lied to each other was that conflict in action. It's been there from chapters 1-2, really, as Remus made that list of 'activities' for them.
That's a really amazing feat of writing you did just there, you know. :)
