Ohmygosh! You have their banter down pat. ^______^ (And as far as I can tell, none of it is from the book, so I wouldn't worry.) I'm so amazed at how perfect the dialogue sounds! And so much love for the Ender/Alai moment. *_*

Alas, I don't know of good Ender's Game fic. I did come across a decent one on ff.net and a few, er, mindbending ones on enderslash several years ago, but that's about it. (And certainly not enough on Dragon! ;_;)
