I agree with Carry. The haircolour, the eyebrow shape... there is nothing in this person that reminds me of Silver.

Hmm... so the Gray-story will be an actual series rather than a single chapter after all. I wonder how long it'll turn out to be.

That black-haired girl reminds me of Kamika. Both the face and that standing strand of hair, though I don't expect there to be any connection between them.

But speaking of that strand, it's just like the one Mavis had. Maybe she's Mavis sister.
