I listed a number of reasons she'd never be a Scion. This isn't me hating on Wuk Lamat, this is me looking at it from a logical perspective. The Scions traveled to the far ends of the universe to prevent an extinction level event. Wuk Lamat is scared of giant colibris. Scion material?
EDIT: I love Wuk Lamat to death. I just found her annoying when she didn't stay home.
