I have to admit I'm very disappointed with this chapter and its resolution. After introducing the Two Annies Situation as one of Loup's dastardly tricks, but denying an immediate solution and having the two of them co-exist for a period, while raising questions about which one of them is "more real" and whether going back to one Annie might involve the uncomfortable possibility of one of them being winked out of existence… and getting a lot of great character interactions and development out of it… to just decide "oh yeah, Zimmy merged them, nbd" is staggeringly anticlimactic. It doesn't feel like the metaphysical questions have been resolved, nor that Annie (as a whole) has actually learned anything during her separation period that she couldn't have by her lonesome. Tom may have shown himself to be a master of tying seemingly-unrelated things together in a very satisfying way, but right now, I'm left wondering what the point of any of this was.
