It seems pretty clear that Wanda has/had some agenda of her own. A couple thoughts that occurred to me:

1) We don't know what she was doing in Faq. Was she a native? She didn't look like the other natives, IIRC (without going back and checking, admittedly).

2) So...is she part of Stanley's force, or is she ALLIED with Stanley? She could be his Vinnie, as opposed to his Webinar. If that's the case, maybe she dissloved her alliance and is thus "moving" independently, like Ansom had in mind for his excursionary force. One wonders whether a single unit could ally, and if an entire side must ally, what "side" might she be on?

3) As long as a unit's leige or whatever is around, how could a unit switch sides? Which adds some credence to the possibility that Wanda was not part of the Faq faq-tion , but rather part of some other, not-yet-identified side.
