Without the option to reveal himself and showing Ladybug that he is no just trying some blind justice in that particular case, he is just there, grabbing with his shaking hands and some salty tears a particular old photo album full with his mother's pictures, pictures not only of hers but him as well and of course some when it was his father there too like the happy family they were one day in that past, a past that they can't even have anytime again. Unfortunately for him not even as the superhero that he is, he, Adrien Agreste, couldn't do much rather than just be there and let his tears fell down to his most precious memories of his mother.
