Tessa was walking in the halls of the Institute. She was hearing whispers from everywhere.
"William Herondale....."
"Who is there?" she asked with panic in her voice.
"James Carstairs....."
"Show yourself!" she yelled, looking all around herself without seeing anything. The pictures on the walls looked real, it was like they were moving. The Angel Raziel with the Mortal Cup and Sword, coming out of the Lake Linn. She stared at one of the pictures and heard a silent whisper again.
"Both of them want the same, but only one of them will get it....."
"What are you talking about?"
"The heart will show the way......"

A knock on the door woke Tessa up. She quickly got out of the bed and put on her bathrobe.
"Come in" she said.
The door opened and Sophie's face showed up.
"Good morning, miss Gray, there is a letter for you. I-I thought that you might want to see it now."
"For me? Yes, thank you, Sophie"
"Do you need help to get ready for breakfast, miss Gray?"
Tessa really liked Sophie, she was always so kind and helpful.
"Yes, please Sophie"
Tessa took a fast bath. She was wondering who might have wrote her a letter, and hoped it was not Nat. After the bath she wrapped a towel around her and sat on the bed. Sophie took a comb and ran through Tessa's hair with it. Tessa's memories flew back when her aunt used to comb her hair. Finally, her hair was done and Sophie helped her get dressed.
"Thats all, Sophie" said Tessa and the other girl left the room leaving her alone to open the letter.
Tessa quickly opened the envelope and started reading.

Dear Tessa,
I'm writing this letter to you, so you don't worry when you don't find me at the Institute. I think i speak from all when i say that i'm not needed there. You will ask why i talk like that? Well, look at me! I'm so weak that i can't even stay on my feet without taking the darn drug! I can't help the others, not in my condition. Thats why i left, i don't want to be a burden to them. My condition is like an Angel's punishment, for wanting what i can't have. Please Tessa, don't come after me. Tell the others that i'm so sorry for not being able to say goodbye in person. You will probably never see me again. All i want from you is to keep me in your memories and never to forget me, because you will always be on my mind.
Farewell my dear Tessa!
Kind regards,
Jem

Tessa was shocked! Jem left! Why would he do that? Why on earth would he think that he is a burden?! She ran out of her room,down the stairs and into the dining room. She looked at the people's faces and of course she didnt see Jem.
"Anyone seen Jem?" she asked, panicked.
"He is sick, in his room." said Will.
Tessa turned around and ran up the stairs again to Jem's room. She knocked on the door.
"Jem?? Are you here? Jem, open the door, please!"
She opened the door and saw the empty room. His room looked just like hers, but the smell was different. Jem's room smelled like different sweet spices. Of course Tessa knew that it was from the drug. The Drug! If Jem was gone he would have......taken it...yeah, he did, the box wasnt on His bedside table. She sat on his bed and covered her face with her hands. She wished she had stayed with him last night, if she kept listening to him, he wouldnt have left, it was all her fault! She missed Jem. His bright smile, everytime he saw her, the happiness in his eyes when they talked, the passion in his music when she was listening to him.... Suddenly her mind drifted back to her dream "both of them want the same but only one of them will get it" could this have something to do with her dream? Jem....she needed Jem here with her, he was her closest friend. She had to go after him.
Tessa left Jem's room and went back in the dining room, where the others still had breakfast.
"How is Jem?" asked Charlotte.
"Good" said Tessa. She didnt want to tell Charlotte about it because she didnt want to worry her. The rest of the breakfast was silent. Sophie took the empty plates back to the kitchen.
"Will, i will need you and Jem to do something for me today."
"Name it, Charlotte"
"I want you to go and check this address for Mortmein. We have some evidence that he has been there for a few weeks now. Can you do that?"
"Of course,i will go get Jem and we will go as soon as possible" said Will and took the note with the address. He stood up and walked to the door. Tessa went after Will and for the first time since he pushed her away, she touched him.
He quickly turned around shaking off her hand from his shoulder.
"What do you want?"
"Will.....we need to talk..."
"If you are going to tell me that you have a crush on James, then i cant help you" he said with a sarcastic tone and turned around again.
"No! Will wait! Its not that.... Jem....Jem is gone"
