The orange horns catch Minako's attention as they board the subway. It's a very distinctive feature, and she thinks she recalls seeing it previously amid the crowd of new arrivals, although she hadn't spoken to the owner then. Still, there could be any number of grey-skinned orange-horned young ladies in this city so it's not necessarily the same person...

But, she does look pretty confused, which is why she leaves her brother's side for the moment (he's dozing on a seat anyway, he won't mind) to make her way over to the girl.
