So, we know that the holders of the second level of the Miraculous, aka the Zodiac Miraculous will be the kids in Marinette's class, and she will be chosen to hand them out. My prediction is that this will happen in the last few episodes of Season 3, or a later season. But which kid gets which Miraculous?
Well, to start off, I don't think Lila will be getting a Miraculous at all. She is the one person in the class (aside from Chloé, who we know will get a redemption arc), who is a legitimately bad person. She lies and manipulates people, and as for the whole "You haven't seen the last of Volpina" thing, I think she will become a recurring secondary villain, due to not forgiving Ladybug, which furthers my point about her not deserving a Miraculous.
So my predictions for the other kids' Miraculous are as follows:
Rat-Sabrina
Ox-Ivan
Tiger-Alix
Horse-Juleka
Goat-Mylène
Monkey-Kim
Rooster-Max
Dog-Nathanael
Pig-Rose
And for the Dragon and Snake, we know we'll be getting two new students, Kagami and Luka, so I'm betting they're the holders of the Snake and Dragon.
Let me know what you think!
