I also don’t think what happened between Emma and Graham was love. Were they attracted to each other? Of course. But physical attraction doesn’t qualify as love. But I do agree that had Graham survived, they might have developed something very strong.
But the kiss between them still confuses me. True love’s kiss is what breaks curses. True love. I can’t help but think that the writers wrote that scene before Skin Deep was completed. It seems as though the writers didn’t have their mythology in regards true love in order until that episode was written.
