The fact that Blue had this on her person (considering that she should have had NO magical items after the curse, let alone one that was hidden in her convent) was espeicially suspicious. One could make the argument that she got the supplies to make the memory potion in S2 from Golds shop, which would make sense, but how could have had the wand hidden if she had no memories or knowledge of magic? I had. big problem with this >_>
I recently saw a tumbler meta that tied Walsh to fairies & Oz, as well as the blue fairy to Oz…. (blue, green & black fairies were mentioned off memory)- will see if I can locate it & post here.
