Okay, I'm starting to think that JB needs a CONTINUITY OBSESSED beta reader, because I just caught another plot-hole.
During the meeting with Nicky and the Nickelheads at Shedd Aquarium in Small Favor, after they raised their pentangle or whatever it was (pentagon? pentacle? pentagram?), to cage the Archive and shut her away from help...?
Why, exactly, did Anastasia Luccio, who was present and did have the item in question, fail to simply use her Warden's Sword-- made to cut through ANY enchantment-- to cut through the barrier and charge in to help with Murphy at her side, and Michael and Sanya not far behind?
Ooops.
