With all the talk of new Miracles and Kwamis and events, there's one thing that admittedly isn't being spoken of much: Lila's role in Season 2. We know from what's been revealed that Lila is going to take over the school and win Adrien's love in the only way she knows how: by lying, cheating, and manipulating her way to the top. It'll be to the point where Marinette and Alya will have to work with Chloe just to stay one step ahead of her, which seems partly to preserve the status-quo but mostly to keep Adrien out of her hands. Hawkmoth also hints that she as Volpina will return, but he can't always have a butterfly sent her way when she's upset and so I think he might arrange it so she can transform at will. Girl's got plenty of hate for Ladybug to spare, after all, and having access to her illusions would make her goals for the school even easier to reach.
I had some hope that no matter what wickedness Lila started, Marinette would at least try to befriend her as a token apology for what happened before. Instead, this kinda makes Mari look bad because it implies that she STILL didn't learn anything from "Volpina" and is again letting her jealousy make her act very un-heroic.
As to Lila herself, it looks like the show's going all-in with making her the Miraculous version of Eddie Brock from Spider-Man. Like Eddie in the original comics, her arc seems to building up to "pride goeth before the fall" as it will most likely end with her being exposed and humiliated in front of the entire school due to Marinette and/or Ladybug (because that's how such plots always end). And when you've got a supervillain who can take your negative emotions and turn them into power, the amount of hate and rage Lila will no doubt be feeling after losing everything could result in her eventually becoming something even worse than Volpina.
But that's just how I see it.
