Well now i was way off on guessing what lumi and vanille were saying when i saw the raws lol i thought she had told her something like you mated with youta i bet that's why she vanille makes that face can't wait for the rest of the translated chapters it's gonna be a real shit show
I bet that "clown" girl is the actual witch and "Maya" was something like a "puppet" / decoy she controlled with her "magic" (lost technology maybe).
Then the real witch pretended to be that useless "clown" while creating the image of "Maya" being "Galia".
So now that the guardians of Secondary have revealed their trap Galia could dispose of her decoy as there is no further threat to her.
The only thing left would be that she either reveals herself soon or that she (the clown girl) slips away when no one is paying attention.
