Marinette Dupain-Cheng.. or rather, Marinette Parker, the older sister of Peter Parker, although there is a 16 year age gap between them, Marinette swore she'd always protect him.

That didn't change when she went to Paris

With Lila and the Akuma's and Ladybug

That didn't change when she got kidnapped by Hawkmoth

That didn't change when Peter got bit by a spider

That didn't change when Peter became Spider-Man, or an Avenger

That would never change.

Although.. she'd failed.

Marinette Parker had failed to protect her brother from Thanos, from the Green Goblin, from Aunt May, from Mysterio

Dr Strange had erased everyone's memories of him

But hers

Because Tikki is literally a goddess of creation, Marinette couldn't be cursed like that.

Marinette walked into the hotel room, and not so surprisingly, Peter was already there.

"Peter-" Marinette began, but he interrupted her

"Nette-? You remember me?"

Marinette laughed

"Peter, darling, I'm your older sister, I could never forget you."

Peter ran into her arms, and the two of them sunk to the floor, Peter sobbing, Marinette smiling somberly.

"Mari- I want it to stop. It hurts it hurts! Mari they don't remember me!"

Marinette sighed, and pushed the boy back, just a bit, so he could see her face

"Then let's do something about that."

"Wha- what?" Peter asked, voice shaking in distress.

"..mon bogue, i picked up some things in Paris."
