I think Lila will figure out the kwagatamas force Nooroo to give her one and talk to Gabriel. She has a plan that involves Adrien finding out the truth (idk what or why), and lie to gabe pretending she has another plan, (or she does also have another plan but only telling Gabe this other plan.)
Obviously, he won't believe her. But you know who he would believe? Nooroo. I think the wizard that made the miraculous and put spells on the kwamis (according to plagg saying "you forgot about the magic spell" from sandboy) where they can't lie to thier owners. Gabriel is no longer his holder. So Lila forces nooroo to lie to Gabe.
So blah blah blah they do a plan and somehow during the fight it's revealed to chat-noir and ladybug. Chatnoir is shocked, Gabriel gets mad at Lila and nooroo.
+Bonus if a reveal was right before or after like if chat-noir acts too angry (he has the right to be angry but not as angry as adrien, who he is, but no one knows) Marrinette will later put two and two together. Marrinette will comfort Adrien as he doesn't know she's ladybug. She'll fell bad and nearly say something but will decide not to.
