BETTER YET!
Have either Tom or Sabine get akumatized over Marinette being treated like shit! That way we have a poignant Marinette focused episode about her struggles and her parents, we give Tom/Sabine something to do, and we don’t need to Akumatize Marinette thus having her blame herself for the shit that has happened to her, while still having some catharsis over the narrative treating her like shit.
A win all around.
