Or more accurately, the stars.

Summary
Shadow feels cold, and unsteady, and he balances for a fight, and Sonic mockingly coos, "C'mon now, Shadow. I'm Super, what's a little Chaos Spear gonna do?"
Shadow fires one anyway, watches it fizzle out on Sonic's chest, his expression bored, dismissive. No, worse, Sonic looks amused. "S'just Chaos energy, I'm practically made of the stuff right now. Just charges me up. Like a battery." Sonic's eyes, red, land on Shadow's wrists, his inhibitor rings, and he looks hungry. Sonic says, slow, "You should take those off."
Shadow tenses, "That's a terrible idea, we'll level the country."
"Aw, I can take it, I'd stop you."
Sonic's hand curls around Shadow's wrist, and Shadow makes a panicked sound, curls his paw over Sonic's, inhibitor ring captured between them, and Sonic laughs, "Hey," he leans in, close, too close, "How's about a game?"

Little does he know that finding his friends will only add to the questions he needs answers for.
Meanwhile, Eggman is in a foul mood after being trapped in Cyberspace. Despite the setbacks to his plan, he has enough of his infrastructure set up within Kronos Island's mainframe that he can manipulate parts of it to his ends. He figures out how he can make the most of his set-up to still execute his master plan, instructing his mysterious assistant to keep a close watch on Sonic as he comes up with his most diabolical scheme yet.

Summary
"S-Shadow?"
The ebony hedgehog narrowed his eyes at the look on the hedgehog’s face. It'd take him a billion years to decipher what those wide emerald eyes were thinking. "How do you know the name that I go by?"
Tears invaded Sonic's vision, never did they fall, even if he ignored every emotional wall he’d ever built, breaking through like a wrecking ball. Frozen in place, unsure whether to leap towards him or run away and attempt to bring coherence to the situation, a single tear rolled down his cheek. It was numb, he couldn’t feel the warmth of the salt his body produced. He didn’t know whether to be relieved or even more terrified at the sensation.__
Sonic expected there to be some troubles in this new adventure he found himself in. After all, someone was stealing his identity to destroy military bases. What he didn't expect though was to wake up in his clockless house... on the MOON.or
Sonic finds himself in a time loop, and the only way it breaks is if he convinces Shadow that he knows him (at least that's what he thinks).or, or
Sonic Adventure 2 with a strange, almost eerie change of events and then a rewrite of the July calendar. -
