Omori and Sunny both have a love for sea angel themed lights (sadly, those things don't exist for some reason) I also do think that if Omori still exist in whitespace, he gained access to more art material because of Sunny's better mental state. So when Sunny goes into whitespace, he and Omori just craft up little lights.
Now I normally like to think that Omori ended up disappearing back into Sunny’s subconscious because he served his purpose (Omori was his escape from reality, but Sunny didn’t need to escape anymore because he was strong enough to live through the good and the bad) but hmmm if Omori still existed in some layer of the subconscious, I like to think that Sunny would want to make things nice. Let’s run with this together for a bit nonnie :D
Omori faded after the Final Duet, and he thought that was it. He had hated Sunny for so long (Was that hating himself, or hating his creator? He wasn’t Sunny, He was Omori, but Sunny was Omori. Did that make Omori Sunny? It was easier to just try to stab the older boy than try to think about it)
Then Sunny hugged him. Omori was used to hugs from his friends, even from his big sister Mari, and he thought he knew how they felt. Nice, but flat. Like looking at a picture of a delicious food. It seemed delectable and desirable, but there was no substance.
Hugging Sunny felt real. Omori had never really felt real before, except in the moments where he was scared. He had thought reality only included bad, that was why they were in headspace wasn’t it? But this hug was real, and Sunny was real, and Omori felt warm for the first time.
He faded, the steak knife he had for so long slipping from his fingers. He didn’t know what fading meant, but he saw Sunny walk through the door before his eyes couldn’t see.
There was nothing. Then there was White Space. Usually when he opened his eyes in White Space he had the same two thoughts.
Welcome to White Space. You have been living here for as long as you can remember.
This time he didn’t think anything. Omori simply existed. One minute he was faded, the next minute he existed once more. Mewo slumbered in the corner of his white rug, and his laptop was booted up already. He had his box of tissues, full now instead of almost empty, and-
His sketchbook. It was...new. His sketchbook had always been dirty and beat up, the paper crinkled at the edges. It was filled with drawings that scared him, drawings he knew he did, but also had no memory of ever doing. This sketchbook was sleek, black leather with his name on the cover. Next to it sat a pack of full sharp colored pencils. Omori stood and walked over to it, kneeling down and picking up the pack.
He had never had blue before. Or green, or purple. Now a full glossy rainbow of options peered out at him. He tucked the folds back into the box carefully, and picked up the book.
The pages were crisp white, empty new canvases for him to fill. None of the pictures from Sunny’s bad dreams, or the fragments of Black Space he couldn’t fully get rid of. Just...new.
Things began to appear in this fashion. Omori would fade, and he would come back, and his Space would be made different by additions. A ball with a bell in it for Mewo to chase around, a soft blanket that looked like it was made of stars, even a new light, no longer a dark bulb filled with the dark parts of headspace, but a string of twinkling sea angels, hanging on nothing above him.
Things were added, things with color and sound and feeling. Things that made Omori feel...real. The same feeling he got while hugging Sunny. Only one thing was taken.
White Space was missing the door out.
