At the same time, however, it sort of made sense. Sora isn't as serious as Chloe, but they do share the expertise with knives. Tsukasa is Kirika, sharing the amnesia and the lost name. This can further support the Sora-Chloe comparison because:
[spoiler]Sora, in the series, wanted to be Tsukasa's friend.[/spoiler]
That leaves Mireille and Altena. Subaru being Mireille is arguable, but something in me insists that Aura fits the bill better. Altena could be Morgana.
Eh, the Wizard of Oz theory was alot better.
