"Sirius?" Lily called a bit tentatively. "Sirius, are you OK?" She leaned in a little closer to Sirius. "What's wrong? What are you doing here, in the corner?"
Lily reached out to push his hair out of his face, he flinched, and one large shiver seemed to slowly make its way down his body, before the rapid shaking started anew. Lily had pulled her hand back, startled, when he had flinched, but she reached timidly forward again, this time to put a comforting hand on his quivering shoulder. Sirius made a sound halfway between a yelp and a grunt, and Lily backed off once more, getting to her feet.
"Magus!" She shouted. Hearing his name called, her owl flew into the room, stopping inches from Lily's face, a piece of blank parchment in his beak. Magus held out his leg, obediently, ready and waiting for Lily to attach a letter to it. Lily reached into her pockets but she didn't have a quill or even a pen or a pencil on her. She whipped out her wand. "Accio Pen!" She shouted, thinking it easier to write with an object that didn't need to be dipped in ink first.
However, seeing as she had made the spell so general, not focusing on one certain pen, every pen in the flat, even ones Lily had thought lost, flew at her. Drawers opened to vomit up pens. The pens hurtled at her with surprising speed; she had put too much strength into her spell. Magus cried out and flew up as close to the ceiling as he could go, having taken a pen to the chest. From the corner, Sirius let out a sharp cry as all of the pens that missed hitting Lily either hit him or the walls around him.
"Magus!" Lily called for the owl, coaxing it back down. Reluctantly, the owl returned and held out its leg once more. Lily took the piece of parchment, and leaning it against the wall, hastily scribbled, 'Help! Trouble with Sirius! –Lily'. She tied the parchment to the owl's leg with a bit of conjured string. "Take this to James, no matter what he's doing. I don't care if you need to swoop in the kitchen window and disrupt a family dinner or if you need to pick the bathroom lock and interrupt him while he's in the shower. When you find him, peck him until he reads it and gets here. Don't let him brush you off!" Lily threw open the nearest window. "Go, Magus!" The owl zoomed out the window into the city.
As soon as the owl was gone from her sight, she dropped down to focus on Sirius. She sat down on her knees in front of him, and reached forward, once more, this time, tucking his long black locks back behind his ears, so she could see his face. It was then that she realized he was crying silent tears. His eyes had no trace of their normal spark of life, they were dulled and glassy and unseeing, as he gazed, his eyes unfocused, into space.
"Sirius?" Lily's voice was barely above a whisper. "Sirius, talk to me."
Sirius' shaking began to ebb slightly.
Heartened by was seemed to be a breakthrough, Lily tried talking to him again. "Sirius, can you hear me?" When Sirius gave no response, she said, "Guess not. Well, anyway, er, this is Lily, Lily Evans, in case you didn't know." Lily took a quick rest after reintroducing herself to who was one of her closest friends, to calm herself.
Siri, I don't know what's wrong with you, and I wish you could hear me and tell me what's wrong, but you can't, so I'm just going to prattle on anyway, and my god, was that a major run-on sentence! Siri, possibly some part of you recognizes my voice, and hopefully you might, somehow, understand what I'm saying, so I'm just gonna' talk, OK?"
Sirius' shaking was easing up a bit more, so she took this as a sign to keep talking.
"Siri, I'm kinda scared. OK, I'm very scared. I don't know what's wrong with you and I don't know what to do. So I'm just gonna keep you company. I don't know if you're under some weird spell, but if I was under one, I'd be happier just knowing my friends were there for me y'know? Now, James is coming, I know he is. I sent him an owl and I made sure Magus knew it was urgent. James'll be here as soon as he can, I just hope he doesn't get arrested for illegal, unlicensed Apparation in the process. Hopefully he's smart enough to just put on his invisibility cloak and fly over here on his broomstick. You remember James, don't you? James Potter, a.k.a. Prongs? He's your best friend. You, James, Remus Lupin (a.k.a. 'Moony') and Peter Pettigrew (a.k.a. 'Wormtail'), and I guess me too, kinda, are the Marauders. You remember the nicknames, don't you, Siri? Anyways, James is coming Sirius, I promise you, he is. I just wonder where you are—y'know, the essence of you—what you're seeing, what's happening, and if you're OK there…"
