I”m also still in a whirwind of trying to figure out WHO is behind all this. My best guests are secret sister, interdimensional twin or the old chestnut of a relative of someone she busted in the past. But as far as any deep cuts this clearly isn’t it, both due to john’s prefrence to have his works be accesible and the fact any deep cut I could think of makes no sense. I suspect it’ll all snap together in the end of this thrilling three parter, but it adds to the supsense that like Lottie I haven’t the faintest lead as to WHO this person is and why they hate her so bad.
