Very nice chapter, I really liked Abigail's scenes, especially her decision to actually talk to Harry about her intentions.
Nice bit about the Silver Torque and looking forward to seeing how Abigail's discussion with Hermione goes.
One thing I'm wondering about is how did Su manage to conflate that situation with "death ground". Sun Tzu's "death ground" isn't a situation where "There was nothing to be gained by backing down.", it was one where it was literally impossible to back away. (Given the description of harry as the battlefield I'd think it would count as Contentious ground, where Sun Zsu recommends "On contentious ground, attack not.").
I really wonder what Su Li's reaction to hearing about Abigail and Harry's talk will be.
Unfortunately the only character I can see thinking of that is Snape, and he's rather busy at the moment so might not even be aware of the problem. The wizarding world characters don't consider muggles as able to tell any witch or wizard what to do, so won't think of it, and Harry is Harry.
