Honestly I think an interesting way to develop Adrien’s character in season 3 would be to actually let his mistakes start to come back to bite him. Not anyone else’s actions but his own actions and inactions.
He stopped Marinette from revealing Lila’s lies because it wasn’t really hurting anyone? It was shown as the wiser and more mature way to deal with Lila in the Chameleon episode?
Fine.
Show that coming back to bite him. Show that lies on the scale Lila says aren’t harmless and passivity just makes it worse. Show that saying it and practicing it are two entirely different things, when Lila is purposely trying to hurt one of his closest friends.
Show that the original message from Origins isn’t being contradicted and that staying silent was the wrong thing to do.
Show that Adrien “perfect” Agreste is just as capable of making mistakes no matter how good his intentions are.
Hecc give him his own bully, because I can’t imagine everyone loving someone as perfect as Adrien and let him find his own strength as Adrien.
Please just give me more than “poor puppy Adrien who is neglected by his father and isolated from his friends and continuously rejected by Ladybug.” Give his character more depth than that.
And for God’s sake, please send a better message out to young children than “we shouldn’t hurt our bullies because that doesn’t make them a good person.”
