{Complete}What If She Was Never Gone?

R.C.G

Magnus took a sip of his coffee and stroked Chairman Meow's coat. He realized he wasn't alone, but didn't turn. He knew who it was. "Do you often sneak into peoples' apartments?"

"You said that same thing to me when I was twelve," said Scarlett.

Magnus turned around. She had her hands in her coat pockets and was looking at him with sentimentality.

"What are you doing here, future girl?" he asked.

Scarlet- if that was even her real name- sighed. "I don't know honestly. I would usually come here to talk to you if I was having a problem I couldn't talk to my family about."

"Flattering," said Magnus flatly.

Scarlett looked at the empty living room. "Could I sit down?"

"Sure," Magnus snapped his fingers and two white couches appeared across from one another.

Scarlett sat down on one of them. She didn't even seem slightly surprised.

Magnus sat on the couch across her. "Coffee?"

"Tea," she held out her hand, perfectly ready to receive a drink. Magnus thought this was kind of strange.

He snapped his fingers again and a cup appeared in her hand. She was about to take a sip, but she paused when she saw the lipstick print on the cup. She chuckled and rested the cup on her knee.

"I missed you, Magnus. I haven't seen you in two years technically. It's been a long time keeping everything to myself."

Magnus wondered how well he knew this girl in the future. He didn't say anything, just looked at her, waiting.

Scarlett sighed. "Can I trust you not to tell Alec?"

Magnus nodded slowly.

Scarlett hesitated, but eventually spoke. "My mission is to keep Clary safe- to make her live. Not only that, but to make sure everything happens exactly right, or I'll disappear, and Clary and Jace will die."

"Why will you disappear?" Magnus asked carefully.

"Clary saved my mother just before I was born. If Jace finds out, she won't be there, and I'll die."

Magnus nodded, trying to conceal the fact that he had no idea what anything was for the first time. "Who's your mother?"

Scarlett glanced up at him. "I thought you would've figured that out by now."

Magnus shrugged. "I don't know everything."

Scarlett hesitated at first, but after a minute she stood up and took off her coat and cardigan. She pulled a knife out of her boot and used it to cut the rune on her right shoulder blade.

A deep red color bled from her roots, and began to swirl into curls. Freckles dotted her face, and her dark blue eyes turned to a shocking clear blue.

She sat back down and crossed her legs.

"Are you Clary's daughter?" asked Magnus.

The corner of her mouth twitched. "That's what she thought, too. No, I'm not."

"Who are you then?"

Scarlett waited another minute before answering. "I'm her half sister."

"Isabelle, are you okay?" asked Simon. "You seem distracted."

"Yeah," said Isabelle. She and Simon were walking back to the Institute, holding hands. "It's just..." she debated on whether to tell Simon or not. "... I think Loren's sister is involved with some dangerous people."
