"Mario's here," the kids whispered to one another, scattering into the nearest rooms away from the approaching plumber. They wanted this to be a private matter, and thought it was better to leave this between the adults.
"Open up already!" The Italian slammed on the door with his fists, still extremely drunk. As well as a terrible hangover, Mario began to feel faint as well, causing him to lash out in anger. Luigi was impressed with how resistant he seemed towards the poison thus far, but it was apparent the plumber hardly cared about his physical health right at the moment. All that was on his mind was getting to smooch his special someone, and then go home and watch more football and get even more drunk.
After a few seconds of incessant pounding, Luigi got irritated with his irritational behavior.
"Hey, bro. I got this," he said, pushing Mario aside, who in return gave him a sharp glare of disgust, panting slightly and resting his hand on the stone wall behind him. Luigi brushed off the anticipation of watching his brother's downfall, and walked up to the door. Slowly turning the handle, the door opened with ease. It apparently wasn't even locked. Mario blew a raspberry at his brother for having common sense, stepping inside to face Bowser.
"Hello, Mario!" the princess waved at the intoxicated tomato of a man. A sluggish, but surprisingly decent gesture was returned back to her. Even in such a state, Mario would never be crude towards the fair princess; she was much too beautiful for it to be possible for anyone to insult her.
Just as Peach was going to ask what him what took him so long to arrive, she was immediately caught off-guard. The man in question started to groan horribly, clutching his stomach and getting on his knees.
"Mama-mia!" Tears formed in his beady eyes, now forced to squint from the immense pain. It was all happening so fast, the poison kicked in after hours of infecting him. No one had even a chance to react; all except for Luigi, who was smiling broadly.
He knew this moment would come eventually, but still, it felt so satisfying to actually witness the slow, agonizing death of Mario. He stared down at his now collapsed brother, feeling no pity for the suffering Italian. Mario, now becoming much weaker, looked up at his brother.
"Help me, bro," he mumbled weakly, trying to desperately find some resolution in his fate. A shaky hand reached up to Luigi in a desperate attempt to receive assistance. Luigi bent down, smiling at him. "It's over, Mario." The red hero's eyes widened for the last time, realizing his brother was the cause of this. He tried to speak, only coughs of blood and mumbled insults sputtering out of his mouth. After a few short seconds, and several strings of muffled cursing, Mario fell still, his lifeless eyes staring up at the man who betrayed him: his own brother.
