What a story! Thank you for not backing away from this idea but doing
something wonderful out of it and sharing it with us. Your great job
with the characters is more evident than ever, this setting highlights
the subtle (and the not so subtle) differences between the Harries and
Rons of your different universes. This was perfect: His quills were
nibbled in the same way on the ends.

It's also kind of sad; the huge difference between the worlds. Two
Households can never, despite the happy ending, be as cheerful as
Checkmate, ever. Poor THh:Harry, to get to hear about all that he
hasn't, and that he never had. I wonder if Ron also learnt to value
what he has.

And oh, I would be a happy person if I could se the result of Harry's
question in the end!
