Omori Bad Ending Aftermath

Omori.

Everyone was silent. They didn't know what to say.

Sunny had woken up, differently.

Claiming to be...Omori.

"What the hell.." Aubrey started breathing heavily.

Kel didn't know what to say, so he just kept silent. 

Basil was sobbing. And Hero? Well....He tried to have the courage to visit Sunny and Basil but ended up even more shattered.

"You can't be fricking serious," Aubrey growled. She had enough of this.

She grabbed Omori's collar and glared at him. "You think this is funny?!"

Omori looked at her blankly. "Actually no, you're holding me by the collar so I presume this is not a funny situation." 

"DON'T PLAY WITH ME SUNNY." Aubrey shook with anger. 

Kel immediately grabbed her. "Aubrey." his voice broke. "Stop it." ...He didn't know what else to do. 

Basil wept, while Hero stared at him quietly with a blank expression, confused and done about everything.

"What a pathetic bunch," Omori said blankly.

They all looked at him with shock.

"You're Sunny's friends? Of course, he created me to protect him! Well guess what?! HE'S DEAD. Because of well, me! And he created this stupid little world that I'm part of that includes you. I didn't want to partake in this anymore so I jumped off. Happy now with the explanation?" Omori gave a sarcastic expression.

Kel fell to the floor, paralyzed due to trying to take this all in. What was happening?

And why.
