Visages represents Verso.
Visages is He Who Guards Truth With Lies.
Here's the secret to understanding the game's story: Verso *always* lies when he has the chance. He always recruits the people who know him best--Monoco and Esquille--to both lie for him and to cover his lies.
Even in the one moment in the game where he has the chance to own the truth of choosing to let Gustave die, only the player's agency can get him to admit the truth--AND THE GAME EVEN FLAGS THE LIE.
There's only one time Verso voluntarily tells the truth: as he is dissolving in Maelle's arms, after she beats him and he knows he'll never be able to shut down the Canvas, and only then because, for the first time ever, he's helpless. No lie he tells can possibly get him what he wants.
So, in that one moment where his masks are finally gone, all the excuses stripped away, what does he beg for? Not for his family, for their healing, for their freedom, as so many who want to lionize him claim.
He begs only for death. An end.
This is the thing people miss about Verso, his fatal flaw in the French literary tradition: for all the lies he tells everyone around him--and the ennobling lies he tells himself--he is, simply, suicidally depressed and unable to kill himself.
Nobody in the Dessandre family handles grief in a remotely healthy way. Probably Verso least of all of them.
