In some sense, Mother Winter indeed has elements of Nemesis-the-goddess
But, Hades' vault kind of smacked us in the face with the Hecate connection. In other words, Hecate MUST be a name to use for the Queens together, or only the Mothers. In any case, I'd say it's canon.
Agreed, Hades' vault DID smack us in the face!
And that's so very,
VERY like Jim Butcher's M.O., hmmm?
I can agree that Hecate
IS canon as one of the Names that Harry could have used (but it might have gotten Mothers Summer AND Winter... or a trinity of Lady / Queen / Mother...).
That doesn't preclude the name "Nemesis" from
also being a valid Name.
As I WAG'ed above, I think Mother Summer was concerned about what Name Harry
might have used, and Mother Winter reassured her it wasn't "that" name; I just don't think "Hecate" would have been concerning in the way "that" Name seems to have been...
... And, I'm pretty sure Mother Summer was too helpful in Cold Case if she was a secret Outsider agent.
I think you mean
Cold Days (the novel between GS & SG); not
Cold Case (the short featuring Molly LadyWinter in Alaska)...?
One of the things people have noticed is that a bunch of the major players seem to be "grooming" Harry. Training him in specific ways, prodding him to this goal or that. Even 16yo Harry's fight with HWWBh is WAG'ed to have been more the Outsider evaluating/pushing Harry, than any sort of "fight."
I have no problem with the idea that a Nemfect'ed Mother Summer might have been "helpful" to Harry in ways that advantage a long-term plan, at the apparent expense of a short-term plan...
For example, I have separately WAG'ed that the REAL point of the
Cold Days assault upon Demonreach was
NOT to breach the entire island wide open. It was to provide cover for the underwater action, the REAL plan:
the Fomor's jailbreak of a single entity... who features prominently in
Battle Ground.
