Disclaimer: There once was a girl who liked to write stories. However, she did not write Harry Potter. So she was sad. The end.
Catch Me, I'm Falling
It had all happened so quickly.
One moment he was fighting, winning, laughing. The next, the ground was disappearing. He could feel himself slipping backwards, through some sort of cloth.
He'd been hit, too. The spell sent a tingling sensation over his entire body, mingling with the feeling of falling. It hovered just on the border of pain, a minor annoyance really. He mentally laughed at his cousin. See, she hadn't really beaten him. He had just tripped.
No one bests Sirius Black.
He slipped completely through the curtain now, and was only mildly surprised to find that there was no ground on the other side. There was only color, only blues and silvers and greens all mushed up together.
The curtain wasn't there anymore, either. It was just Sirius now, alone with his colors. He felt his body, straining, shimmering. It wanted to join the colors. He watched as the spell glimmered in the strange non-light. It was green, matching the swirls.
Green was important, he remembered. One of the important spells was green. But which one? He couldn't recall Bella ever using any other spell than...
Oh. That one. Damn his cousin.
So he was dying, dying and falling and disappearing all at once. And he wanted to call out for someone to save him. But they had all vanished with the curtain. Remus, Harry, Tonks, Ron, Hermione, Arthur, everyone was still out there, fighting. Trying to save themselves. So there was no one here to save Sirius.
In retrospect, he should have stayed home. He should have sat by the fire while everyone else rushed to the Ministry of Magic. Then, he wouldn't be floating here in nothingness.
If he had the chance again, he would have done the exact same thing. Because it's worth it, dying to save the people you love. His eyes drifted shut. Besides, now he could see James and Lily again. That was good.
He had missed them.
