Queenie being a Red or a Blue does not make much sense either, because they are not part of the story. If Cortez is alive... What happened to McAllen... we don't know these things. And none of them met Zoe before to say "When you visited the first time", mind you.
We haven't fully been told the full nature of the Kin. April is The Dragon of Spring. How was she a dragon? We know that April is the daughter of the White of the Kin and that Saga is her reincarnation - but how these things come about remains somewhat of a mystery. The connection between cyclical forces, transforming energy and the Kin is fuzzy at best. In the end, maybe Queenie gets lumped in the category of Unexplained along with Uncle Garth.
Note that Helena Chang and Queenie are Asian, and that WATI is a Japaneses Corporation.
