In an alternate universe, during a winter vacation, Y/n aka SMG5 died drowning in a frozen lake shocking everyone except SMG4, who seems to be acting suspicious when Y/n fell into the lake that had a sign that was removed that said "thin ice" on it.

When the gang tried to save him, SMG4 already made it clear that it's already too late to save him, but Mario couldn't let his own best friend die on his watch. He is determined to sneak out late at night during a raging snowstorm, but he never returned the next day, causing everyone but SMG4 to worry about Mario's disappearance.

Eventually, everyone but Meggy and SMG4 went out to search for SMG5 and Mario but they went missing during the terrible snowstorm at the dead of night.

Because of the multiple disappearances, Meggy decided that she had enough and forced SMG4 to spill the beans and he admitted to Meggy that he was the one who took the sign away from the thin iced lake that lead to SMG5's own demise because he was jealous of how popular SMG5 is and he did it because he wanted to be famous once again after he gets SMG5 out of the picture.

Meggy could've been more furious at SMG4 for doing such a cruel and heinous crime to the person that saved everyone multiple times just to gain fame and popularity through jealously.

So Meggy decided to leave SMG4 in the cabin and go out into the night through the harsh blizzard to find her friends, but met the same fate like the others when she was shocked to find all of her friends all dead and frozen solid before seeing her boyfriend, SMG5 back from the dead as a freezing ice cold zombie, who currently has some unfinished business with SMG4 for killing him.

Later that night while SMG4 is sleeping peacefully in the warm and cozy log cabin, there was the sound of a howling blizzard along with the sound of someone pounding on the door as the vengeful spirit of SMG5 demands SMG4 to open the door, which SMG4 did exactly what his former friend told him to that became the biggest mistake of his entire life.

As soon as SMG4 open the door, everything went pitch black and SMG4 felt the icy chill shuddering down his spine as he soon got what he deserved from his former friend as Y/n stabbed him in the neck with a icicle that he made with his frostbitten hands and SMG4 soon died from instant hypothermia from SMG5's ice cold vengeance.

After the deed was done, Y/n left the cabin, but not before saying something to the dead and frozen solid SMG4 to go back into the raging snowstorm, never to be seen again.

"It's true to what they said, SMG4 that "revenge" is a dish, best served cold and you now suffered the icy cold death of vengeance. I'll never forgive you for what you did to me SMG4. I lost the only people I loved and cared for and it's all your fault after everything I have done for you and everyone because of your jealously towards me. Just remember this from me, SMG4..."

I DESPISE YOU, SMG4!
