Summary
Shadow repositioned Sonic’s shoulders, “Posture, Wentworth. How will you play anything if you can’t even sit by the piano?"
He kept his hand hovering over Sonic’s back, touching it every now and then. With the other, he followed Sonic’s hand as they pressed on the keys, gently lifting them to shape a claw, “Pretend your hands are spiders, they effortlessly jump to every note, weaving a song, while never losing its composure.”
Shadow fixed his chin, and his arms, hands again, while never fully letting go of his back. Remain focused, Sonic thought, play the notes, keep proper posture.
But Shadow’s hands were soft.

Summary
The memory comes back to the forefront. After three weeks of silence, G.U.N and the Resistance came to an agreement and decided to ask for the public's help in hopes of a tip on where he'd been taken. Without Sonic, G.U.N had faltered behind even with Team Dark on task. He slams the file shut immediately, other important documents strewing out in the process. A cocktail of emotions floods his mind. Emotions he doesn't have time to analyze or focus on. The hybrid forces himself to take a breath, in and out, the ringing in his ears is a stark similarity of the gunshot ringing out. A reminder of yet another failure attached to his name.
Like a sick joke, the blue fool in the photo is smiling at him, the light radiating from the photo contrasts Shadow in ways more than one. Freedom in light, trapped in shadows. There's a reason Sonic is refereed to as the Light. A savior.
The laminated paper crumbles in his grip.
Or: After being tricked by an illusion of Maria, Shadow is rescued and nothing bad happens!
…Right?

Summary
Shadow shook his head. "It doesn't concern you."
For a moment, Maria just stared at him, too shocked to come up with a reply.
It didn't concern her. He had never told her something didn't concern her before. He'd said something was a secret (which meant it really was a surprise for her) or that he wanted to think about it alone, but he'd never dismissed her like this before.
"Excuse me?" she replied slowly, sounding angrier than she'd meant to.
When Maria wakes up from a nightmare that ended with her death, the world isn't quite right anymore. Shadow begins acting strange not soon after, and on top of that Maria finds herself reliving the same day over and over. With her being the only one to notice and the adults not believing her, it's now up to her to figure out just what exactly is going on—not just with time, but also with her brother.
