Lea was free for a time from the restrictions of Winter Law, that she may miss, we have seen how Aurora and Maeve both chafed under the Law, so that’s why there is a degree of wistfulness about her Nemfection, as well as negative emotions. Unfortunately there isn’t a Nemesis Anonymous, Lea is the only current survivor. Perhaps she can be a sponsor to Justine? I can see Harry suggesting that.Nemesis appears to have freed Justine from her pre-existing condition, so again when Justine is free of Nemesis she may be vulnerable.
Goodman Grey could be vulnerable if Nemesis was able to free him of his rent obligation, but he doesn’t appear to be unduly chafing under that. A full Naagloshii might be more vulnerable in that respect and I think Nemesis would love to partner up with Shagnasty, and it might be mutual, like Maeve and Aurora. There might be enough Nemesis in Justine for that. Shaggy eats Wizards, targeting the White council and the Senior Council in particular would benefit Nemesis and Shaggy. Nemesis would want the Gatekeeper, Shaggy, Listens To The Wind. If LTW cannot banish Shaggy because Nemesis has removed Shaggys restrictions then LTW is in big trouble, and he is already injured.
It’s not Goodman Grey I worry about being nemfected..
I think we are due for a rematch with Shagnasty, Harry is trying to get his mental health together in Next Book and Shagnasty is the ultimate test of that plus he is about to be taught shape shifting.
I would point out Harry now lives in a Castle with similar protections to the ruined Cottage on Demonreach which Shaggy found Anathema, and we have learnt you can use a veil or glamour in its vicinity. Nemesis doesn’t know this. As Harry got the Castle after deducing Justine was nemfected.
If I was taking out Shaggy I would use the superpunch built into Harry’s Staff to blow him into the Castle and then have the gargoyles whale on him .
