after completing a new level you approach the castle and see this: your screen darkens and a loud phrase in a distorted voice tells you “INNOCENCE DOESN'T GET YOU FAR” these words made your ears ring and your head hurt, you can see that the flag is broken and lying on the floor and the pole was all in blood, Toad who is trying to call for help against the background of a destroyed castle, the entity that you knew as "mario" began to change, taking on his "true" form, a monster. Noticing the observer (you) you become his main target, and the game shouts at you "RUN!" and so you started running, the clouds and mountains started to turn to shreds, Mario, or someone who looked like him, was running right behind you, smashing and breaking everything in his path...but then, he grabbed you, literally in a matter of seconds, his giant hand grabbed your leg, bringing it to his face, his distorted voice ringing in your ears

"YOU'RE NOT LUCAS..."
