Argh. I guess at this point, arguing about what was said is futile, since there's no tangible evidence of what she said except for in our memories. We can interpret their words and actions in so many ways, and our minds can change what was really said. We'll just have to wait and see what Clamp will do with Kuro and Fai in the future chapters (even though to me they're already practically canon ^^).
You said it perfectly ^__^ It's all left to memory, and is influenced by prior affiliations (eg KuroFay fan), it's a translation in any case so it might have been translated slightly differently to how Ohkawa meant it. This much, I think, is certain: they didn't actually answer one way or the other xD CLAMP are good at avoiding the subject.
I also agree with you that they're practically canon; I mean, I read that someone said that the way he treats Kurogane is just his flirt-y nature - and to an extent, it is, but he doesn't treat anyone else in the same way. I mean, we've seen him glomp Syaoran, but that was more friendly (and because of the promise of alcohol, lol), but he focuses so much more of his attention on Kurogane. And Kurotan gives him the attention right back, though often in a quieter, more subtle (and ninjalike!) way.
But apart from possibly a hug if one or the other of them needs comfort, I can't see us getting any other on-screen action, as it were, alas!
