Marinette runs into the class and quickly gets into her seat, facing the front, meanwhile Lila is telling everyone more fantastical tales she apparently did, though everyone was just letting her talk since they already knew the truth.

Lila: "I found the Greek kwami box and opened it!" She holds up a bulky glove.

Adrien: "Whatever..."

Chloe: "Ridiculous, Utterly Ridiculous!"

Alix and Kim: Arguing

Nino: listening to music

Mrs. Bustier: claps Class quiet down! We are about to start

(note: a slight au where Lila was found out after her first lie, now everyone just lets her talk because it passes time. Also almost all of them know each other's hero identities, except ladybug and chat noir due to hawkmoth. As for why they are comfortable believing Marinette about the miraculous if brought up, she became the guardian in a flashy way when Lila and Chloe weren't there and Adrian temporarily was a different miraculous. Adrien and Marinette are dating and know each other's identities, the plot point were they can't know is stupid. Also no Lila doesn't have a Greek kwami vessel)
