Heheh, thanks! And I agree that actual physical sex between them is almost gratuitous, really. I like them paired up mostly because, as in most of the pairings I like, I like seeing them interact with each other in any form. It's just... that their happiness together is so much more obvious and significant than most other pairings of which I would say the same thing.

Writing them as ambiguous can be fun, though. In my mind they're a couple, but the physical/romantic/sexual part of that really doesn't matter in the grand scheme of things...
