Toy Shop and Merchant

On the 3/6/19 (or 3/7/19, depending on time zone) live stream, Alice_on_Elm_Street suggested that Alice's toy weapons could be upgraded at a toy shop. Building on this suggestion, perhaps Bumby/Dollmaker could be the merchant who runs the shop. For players who have been through "AMR" they would recognize who this is, but to a younger Alice she would be unawares of who this nefarious person is and only see them as the kindly gent who likes children's toys and upgrades them for her, adding a link between games without making it too obvious but still working within the established history and characteristics of everyone involved.
