Full dialog:
Verso: It can’t be…
Maelle: Verso…
Verso: Clea… You’re alive? What happened to her?
Maelle: I bet Clea hated Maman’s portrait of her. So she painted over her.
Lune: And now she paints… Nevrons.
Verso: Can you heal her? Can you change her back?
Maelle: I can’t repaint her, Clea’s the only one skilled enough to paint over someone else’s creation.
Verso: I don’t like this…
Lune: This is going to be tough.
The way the painting power works is never fully explained. Clea was skilled enough to make Clea into an incredibly powerful nevron factory and Simon into an axon slayer that could only be overpowered by Renoir. That doesn't mean no other painter can effect another painter's creation in any way. Only Alicia says this (she lies sometimes and is wrong other times) and it very easily could've been in reference to her inability to overwrite the alterations of Clea, who is a MUCH stronger paintress.
