A/N: trigger warning- you will see a girl with cuts on her arm in this chapter and possibly other ones. You will not see any actual cutting, just the scars.

The halls were packed with students waiting for the bell to ring to mark the start of the day. Isabelle immediately noticed that everyone seemed to be in distinct circles chatting excitedly about their summers. She even found herself in her own circle with her fellow Shadowhunters. Not that anyone could tell they were Shadowhunters. Glamour a covered their runes and they were not visibly armed. Thankfully, the metal detectors at the front of the school didn't pick up adamas.

A harsh buzzing noise sounded and the crowd began to funnel into the classrooms. Her first class was American history which she had with Simon and Clary.

Jace had English first so he gave Clary a quick kiss before heading off to his class. People were already looking at them a lot. They were new, and Isabelle was very pretty. She had chosen to wear a black and blue top with a pencil skirt and high heels, and although there were girls wearing skirts, no one was wearing heels as high as hers.

She sat towards the back of the class with Clary and Simon.

Everyone was chatting excitedly. They hadn't seen their teacher yet. Isabelle was envisioning an old woman or man who would lecture on in a boring voice.

Although history required previous classes, Clary assured her no one ever remembered anything from them.

A second bell rang and a man shuffled into the room energetically. He was short and balding. He looked to be in his forties and was beaming.

"Ok everyone first day of school! How exciting!" He exclaimed.

Isabelle was caught off guard by his energy.

"So this is American History, filled with pilgrims and wars and whatnot." He said to the class. The he turns to a random student and said. "I bet you already knew that though." He slaps a hand on the desk. He moves across the classroom leaving the kid mystified behind him. "I already recognize some of you from my freshman world history class and studies, but some of you are new,so I'll take attendance."

He pulls out a sheet of paper. And rattles off names.

"Clarissa Fray?" He asks after a few names.

"Here. And I prefer Clary." She responds and raises a hand.

"Ok." He said cheerily and scribbled a note on the page.

He continued on until he reached Simon's name, then Isabelle's.

"Isabelle Lightwood?"

She copied what Simona ms Clary did and raised her hand.

After that he split them off into groups so we could get to know each other.

Isabelle ended up separated from Clary and Simon. Her group had two boys and a girl.

"What's your name again?" The girl asked.

"Isabelle." She answered.

"My name is Emily." She said. She has blonde hair pulled back in a bun and she wore jean shorts and a tank top. "This is Marco." She said pointing to a short Hispanic boy with short hair. "And that's Matt." She said pointing to a short chubby boy with blonde hair.

"Sup girl." He said to Isabelle. "Are you new?"

"Yeah." Isabelle answered.

"So do you not know anyone here?" He asked.

"No I know Simon and Clary." She answered.

"Are they new too?" Matt asked.

"Yes."

"Do they live with you?"

"Yes"

"Are you related?"

"No."

"Then why do they live with you?"

"Because their parents move around a lot."

"Are they brother and sister?"

"No."

"Are they dating?"

Isabelle was really starting to get annoyed by his rapid fire questions. She wanted to get him to shut up but she had been told a thousand times to blend in.

"No." She answered.

"Are you dating anyone?" Marco asked.

"Yes." Isabelle answered.

"Seriously guys?" Emily said. "Could you stop being creeps for ten seconds?"

"Do you not like me?" Matt asked.

"No I don't like you." Emily said.

"Why not?"

"Cause your an annoying creep."

"So how's it going over here?" The teacher said standing in front of their table.

"Fine." Emily answered.

After a few minutes of talking they got back into rows and the teacher handed out the syllabus. The bell rang and Isabelle could already tell she was going to hate this school.

...

No matter what class she was in, Isabelle kept getting hit on by boys. Before she wouldn't have minded and might have even flirted back, but now she was with Simon and after his losing his memory then him ascending, she had no intrest or patience for creepy mundane boys.

She was in a study in which no one seemed to be studying so Isabelle wondered why they called it "study".

"I like your dress." Isabelle turned to see a short girl with short brown hair and thick eyeliner. She was wearing a dress with superheroes from the comics Simon liked.

"Thank you." Isabelle said.

"You're new aren't you? I'm Megan." The girl said.

"Isabelle." She replied.

"What grade are you in?" Megan asked. She say down next to Isabelle and Isabelle noticed weird lines on the girl's arms.

"Eleventh."

"Oh I'm a softmore. What do you think of this school?"

"I hate it to be honest." Isabelle said.

"You and most of the people here. Look I know that most of the people you're going to encounter today are going to be mean, or annoying, but there are some decent people at this school." She said.

"Like you?" Isabelle asked.

"Nah, I fall into the weird and annoying category." Megan said.

"Oh." Isabelle was struck by her honesty. Maybe it was being around Jace a lot but usually people didn't admit their thoughts to strangers.

"Anyway. I have to go down to the library, I hope you find some people worth talking to." Megan said and left.

The girl surprised Isabelle. She was nice. And it was only a few minutes later that Isabelle realized the lines on the girls arms were cuts.
