Sometimes he thinks he might be closer to his lesser Nobodies than his fellow members. Not because he's more caring, or a kinder soul, or a better person; none of that nonsense. Really it's more selfish than anything.
Myde's sisters had been many, all of them beautiful and kind and strong hearted, all of them loving to dance. Not that they'd been exactly the same, with the same wants and needs and hobbies-never that, they'd been so varied, but dancing had been their way, just as music was his.
So it isn't too much of a stretch to think that maybe when he looks at a Dancer, he's looking at one of his fallen sisters. Not that he can tell for sure; in life they'd all been so close that he could tell them apart by a sigh or a footstep, but that was with hearts to connect them, and the flaw in that is obvious.
When they finally complete Kingdom Hearts, his Dancers will get hearts just as well, won't they? So maybe he's a little gentler with his Nobodies, a little more careful-because there's no way to tell a stranger from Avani or Kali or Gita, and he's not stupid like some of the other members think; he knows that while getting his heart back is worth it, it will still be painful enough without being alone. Even having just one of his sisters by his side will be helpful, he thinks.
See? More selfish than anything.
