So for this alternate ending, you'll want to play through until you beat renoir in the finale, then make your way back to lumiere where there's a portal waiting. Once you're through that portal, you'll face off against the painted boy which is where things get interesting, actually. When you see maelle and verso arguing about what to do with the canvas, make sure you pick the "fight as maelle" option, cause that's crucial for this path.

The 1v1 fight with verso isn't too bad once you get the timing down, but make sure you're prepared cause you'll need to win this one. After you beat them, things get pretty intense with maelle wanting to stay in the canvas while verso tries to stop the whole painting situation. Just keep pushing forward with maelle's choice, and you'll see verso get gommaged which, honestly, is pretty heavy stuff.

Its kind of a dark ending if you think about it, since maelle basically chooses to live in this painted fantasy instead of dealing with reality. Really shows how sometimes avoiding the truth can mess you up in the long run. Not exactly a happy ending but definitely interesting if youre going for all the different outcomes!
