Hello, everyone! This is my first ever fanfiction so, criticism is welcome! This Fanfic is going to mostly be GabrielxCecily (MY OTP!) and it may later take place after Mortmain is defeated… I'll decide that later. Anyways, you all get virtual cookies for reading this! Okay on with the story.

Disclaimer: Sadly, I am not Cassandra Clare; I do not own the characters. If I did this pairing would be Canon!

Cecily's POV:

I've been At the London institute for a week now. Everyone seems nice- except for Will - and is quite surprised of my existence. I guess it is because my stubborn brother told them I was dead.

I entered the room to find three people sitting at the table, Charlotte, Gideon and another person who I did not recognize. Charlotte looked up "Oh. Cecily, I am glad you're here. This is Gideon's brother, Gabriel. He'll be in charge of your Shadowhunter training." (A/N In this story Gabriel later decides to leave his father to join Gideon)

At that moment Will walked in with Jem and Tessa. "THAT FILTH WILL NOT BE TRAINING MY SISTER! I FORBID IT!" Will shouted, apparently hearing what Charlotte said.

"I AM NOT TRAINING ANYTHING RELATED TO THAT THING!" Gabriel shouted while gesturing at Will.

"WHAT IS THAT," he pointed to Gabriel "DOING HERE ANYWAY?!"

Charlotte, looking extremely angry and frustrated, stood up "IT'S ALREADY DECIDED! NOW, BOTH OF YOU, STOP FIGHTING!"

Will and Gabriel both sat down and mumbled under their breath. "Pardon my Brother." Gideon and I said in unison.

Gabriel sighed and looked at me, clearly annoyed "We might as well start training." He said exasperated. He then got up and exited the room continuing to mumble.

Gabriel's POV:

"Great, another Herondale." I muttered as I waited for Cecily in the training room. I then had a brilliant idea. I decided that I could use Will's sister for revenge. An eye for an eye, a sister for a sister, Herondale.I thought, coming up with the rest of my plan.

A mischievous grin crept across my face as Cecily walked into the training room. "Ready?" I asked, ready to put my plan into action. She nodded. "I must warn you, I don't stand for tears"

She grinned "Neither do I." she said with a taunting tone in her voice. I could already feel my plan coming into action.

So what do you think? Was it good? Bad? Eh I'm not the best writer so I'm guessing the latter. Oh and sorry for the shortness and such!
