Important Cosette things to consider:
Cosette with political and social commitment before and without the Amis and Marius.
Cosette always noticing little changes of people and complimenting the barista on her new haircut or the girl from her lecture on her new dress.
Cosette simply telling everyone how beautiful they look when she thinks so.
Pastel dresses and combat boots.
Cosette taking long walks with dogs from animal shelters through the Jardin du Luxembourg.
Cosette bringing home flowers for Valjean and hanging photos of them on the walls so his room doesn’t look empty and cold like a prison cell.
Just. Cosette and Valjean.
Cosette knitting mittens and hats when it starts to get cold and giving them to homeless people and shelters.
Cosette baking cookies or making soup and showing up at the Amis’ apartments when someone forgets to eat during their finals again.
Also weakly tea parties with the nuns.
