In catalyst we saw that catalyst akumatizes hawkmoth into Scarlett hawkmoth just like when he akumatized queen bee into wasp queen and after the defeat she turned into chloe, maybe after Scarlett hawkmoth is defeated, he will turn into gabriel and ladybug will ask him to give her the miraculous back and for him to show her the secret passage. Maybe he would set a trap by calling Nathalie and telling her to set a trap! Then he will maybe take ladybug to his passage and show her everything and then nathalie will come from behind and akumatize her and will use her to fight cat noir because he is to shy to fight his lady so maybe she would defeat him and take his miraculous! That's why we heard something about chat and ladybug being defeated in catalyst when the first part of season 2 came out and around the same time we saw a spoiler picture showing us ladybug and gabriel in that room with emily. Remember its just a theory.
P.S yall remember the tiny macaroons marinette made for tikki's power ups? The colors were pink, orange, purple, blue, green, yellow, and red and i was thinking about their possible powers and i came up with-
Pink: fairy
Orange: earth
Purple: air
Blue: ice
Green: water
Yellow: lightening
Red: fire
What yall think??
