Finally I get to read the final chapter! (Had to travel back from visiting relatives, and then there was all kinds of work stuff.) Lots of lovely satisfying things here, not the least of which is Remus discovering to his surprise (oh, Remus!) that Molly is fond of him, and also Molly's prodding Remus into thinking about being a part of Harry's life. (If you ever wanted to write a sequel where this Remus and Sirius had Harry growing up, I certainly wouldn't object, heh.)

I really enjoyed this. You picked a neat set of details to twist or reverse, while keeping the characters entirely true to themselves. It's interesting -- and entirely plausible -- to see Remus finding things to feel guilty over even without being a werewolf, heh. And Sirius's unwanted transformations give him a certain poignance, but he's still got that classic-Sirius (endearing) bit of swagger.
