Sokka/Suki was probably my favorite canon ship, since I generally felt that it was made clear what each character saw in the other. But Toph/Sokka tickles me because I think they'd be awesome together and have fun and hilarious adventures. All the characters are still kids, so I kind of refuse to believe that the ships the canon ended with HAVE to be relationships the characters remain in forever. It's plausible, of course, but not necessary. They could just as easily grow out of the relationships as they get older. And...that's where fic comes in. XD
