Jonelias love triangle but instead of the third party being Martin or Peter or whoever, it’s Mr. Spider trying to lure The Mother’s lost child have to the Web where he belongs.
He let Jon walk away all those years because Jon was just a child and needed time to learn and grow in order to become a real Weaver. But now he’s fully grown and understands the world better than most and with the Beholding trying to lay a claim, it’s time for Mr. Spider to get him back.
Elias thinks he’s prepared to win this battle, but the Weavers don’t lose. No matter what the cost is.
