Maybe I'm just misunderstanding, but I have a couple of questions Elegast
- It doesn't make sense for Mab to work so hard to get an extra candidate for Winter Lady if she already has Sarissa and doesn't know about Maeve being taken.
- Who exactly is the Eldest Fetch working for?
What about something like this scenario?
- Maeve is infected by Lea unbeknownst to Mab
- Mab notices Molly and sees potential for something (maybe another way to get a hook into Harry, maybe timey-wimey stuff)
- Mab sends a message through the Gatekeeper to Harry to look out for dark magic (building foundations for Molly's apprenticeship)
- Mab sends the fetches to keep Harry's attention focused away from the dark magic and eventually abduct Molly.
- Black Council operatives including a Denarian attack Arctis Tor, insulting Mab's pride and clearing out extra guards, instead of pressing further in, the attackers retreat before Mab steps in personally.
- The fetches bring Molly to the tower for whatever initiation Mab had planned for her.
- Mab originally was going to bring Molly back, but Harry and company are coming to rescue her anyway so Mab "leaves".
- In the fight, the Scarecrow reveals that Nemesis has infected him (by Maeve in Chicago), but Harry uses Summer fire to defeat him anyway. Mab is smug about her underdog winning the fight. To Mab, damaging the Wellspring is unfortunate, but she can immediately send her troops back.
- Passage of time is altered in Arctis Tor, leaving the Gates undefended for too long. Maeve is the only possible culprit, and Mab realizes that she has been infected, hurting her and causing her fury.
Basically, PG follows pretty much what Mab wanted to happen, but she gets surprised by the attack on Arctis Tor. Mab loses a bit of control of the situation, but thinks things are going to work out anyway in the end. At the last moment, Nemesis outplays Mab and gets guards off the Outer Gates for a time. Eventually, Mab figures out who betrayed her and is furious.
