Uploading chapter 3 the day after, check me! I'm on holiday from school at the moments can write more and faster too, hope you enjoy. Write a review if you want me to continue for longer, I can write a shorter ending of only like two more chapters or I have ideas to make this a longer fic so just tell me what you would like to see :)

"Magnus stepped forward and handed Tessa a pale blue scarf. "Here", he said, "this is something Alec left at my apartment. He has worn it a bunch of times, hopefully you should be able to channel him through it, see where he is." Tessa nodded and accepted the scarf, then shut her eyes, focussing on Alec. She drew on the image of him in her mind, and the scent left on the scarf. The familiar tingling sensation of the change began in her toes then filled the rest of her body with a warm and fuzzy glow. It was funny, Tessa thought as the change took place, that she didn't mind the feeling now. When she had been first forced to transform into someone else all those years ago it had been in a horrific process, resulting in her blacking out many a time.

After several seconds the fuzzing stopped and Tessa looked down at her hands, glad to see that they were no longer her long pale fingers, but the large, nail bitten hands of Alec Lightwood.

"Holy shit" Isabelle said in a hushed voice from the other side of the room. Tessa turned to face her and Jace, both of whom were stood looking half impressed and half terrified. She remembered fleetingly that they had never seen her transform before. Jem and Magnus on the other hand, who had watched this process many a time approached her, asking questions about Tessa.

"Tessa darling" said Jem, his voice full of concern as it always was whenever she changed, "are you okay?" It was more than 100 years ago but she knew he still remembered how awful it had been for her to change at the beginning, the torturous pain, the confusing loss of self identity.

"I am fine Jem don't worry" she replied with a smile, reaching out to touch his hand. Magnus coughed uncomfortably and she immediately withdrew it. For a second she had forgotten that she currently appeared to be Alec Lightwood, and it was inevitably a strange occurrence for Magnus to see his boyfriend touching Jem.

Focussing on Alec's mind, Tessa blocked out everyone in the room and delved into his mind. She wanted to do so cautiously. Whilst in some ways being able to transform into others was a blessing, it was also a curse. She didn't want to stumble upon some thought or memory that was private or personal to Alec, but at the same time she needed to find him as quickly as possible which also involved a certain amount of recklessness.

Images of Alec's life exploded like fireworks into Tessa's mind as she tried desperately to find his current thoughts and locations. Jace and Isabelle laughing with Clarissa Fairchild, a small, brown haired boy with large glasses who had to be Alec's deceased brother Max, and Magnus everywhere, Magnus with Alec, Magnus meeting his family, Magnus lay asleep on the sofa, his head cradled in Alec's lap.

Suddenly, Tessa opened her eyes. Breaking into someone's current stream of thought was like coming up for air after swimming under water for an unimaginable amount of time. Jem, recognising that she had reached Alec's thoughts stepped in front of her.

"Tessa, what is it? Where is he?" He asked her, panic in his voice. Glancing in the mirror on the wall beside her, she realised that a twisted grimace of shock occupied Alec's features. Allowing the transformation to slip, she felt herself become normal again.

"Did you see where he was? Can we find him? Is he okay?" Jace blurted out, his words tumbling in fear

"I know where he is" replied Tessa gravely. "They took him to Idris, he is in one of the cells."

Isabelle said confidently, "I know exactly where they are. The old Inquisitor put Simon in one of them a while ago when he accidentally came to Idris. I know how to get in and everything." She surveyed the faces of everyone in the room. "Well what are we waiting for? Magnus make a portal, we need to get Alec now! God knows what they could be doing to him!"

"Isabelle it's not that simple" said Jem in a soft voice, always the voice of reason. "We can't just make a portal into Idris without telling the Clave, they would have a heart attack, especially so soon after everything with Sebastian."

"But they're hurting him!" She said, her voice rising in hysteria. Although Tessa hadn't known Isabelle that long she had come to observe something about her, something she admired. Isabelle was always the cool headed fighter a shadowhunter she was meant to be, unless it concerned her family. Then she became an even better fighter, yet tended to launch herself blindly into difficult situations. "I know they are" Isabelle continued, her voice shaking slightly, "I could see by the look on Tessa's face. You don't need to protect us you know", she said, gesturing at her and Jace and glaring at Tessa, "we aren't children. Tell me what they have done to my brother!"

Tessa looked Isabelle straight in the eye. She could tell from her steely glare and from the anger burning behind it that she could take the news and focused on her whilst she spoke. She wanted to avoid looking at Magnus, terrified he would break with the words she was about to say.

"Jem, Izzy is right" she spoke gravely. "We do need to make a portal now, regardless of what the clave says. It's a rogue part of the clave doing this anyway, they will surely be grateful we are rescuing Alec. But we have to do it now, otherwise I fear, from what I have seen anyway, that we might be too late."
