So the true Volphina,  aka the Ladyblogger Alya, was revealed a couple of months ago.
Alya, as all we know, is an up-to-date reporter, Ladyblogger, and truth seeker. But like all Miraculous holders, they will have their alter-egos revealed.
I think that in her civilian self, nothing will change she will keep her secret, but when she transforms her personality will be like a sly fox, trickster, and a true master of illusions.
