-*-*-*-*- Jem -*-*-*-*-
Jem knew exactly why he was standing outside Philip's door. Before Grace fell unconscious, he would have been shocked and appalled at himself for the reason.

But he couldn't take it anymore.

Philip was the reason Grace wasn't here with him. Philip was the reason that the Magister even knew of Grace in the first place. Philip was going to tell him exactly where Mortmain was. And then, Jem would hunt him down and kill him.

"James?" Philip asked from the bed, closing his book. "Can I help you?" Jem slammed the door shut and stalked over to Philip, wrapping his hands around his throat. Philip let out a surprised noise as they crashed to the floor.

"Tell me where he is!" Jem shouted at him. "I know you know! Tell me where he is or I swear to God I will kill you right now!"

"I- I don't know," Philip choked out.

"Liar!" Jem snarled. He yanked Philip up and slammed him into the wall, ignoring the fact Philip's face was turning scarlet. "You know where the Magister is! You were his most trusted minion! Tell me!"

"James..." Philip whispered, his eyes drooping. Suddenly, Jem let go, stumbling backwards. His back hit the far wall as he stared with a sick horror at Philip who was gasping on the floor.

"Oh god..." Jem said softly. "Philip, I..."

"You're stronger than you look," Philip wheezed. He looked up. "I probably deserved that."

"I had no right," Jem said.

"No, you did," Philip said, slowly getting up and sitting on the bed, rubbing his neck as he did so. "It's all my fault. I am to blame for everything." Jem shook his head. As much as he knew it was Philip's fault, he had shared part of the blame as well.

"You said Tessa was the way to get Grace back," Jem said. "Did you mean that?"

"Of course I did," Philip said.

"How? How can she possibly help?"

"Miss Gray can touch the mind of whoever she changes into," Philip said. "Maybe she can stop whatever Grace is facing and get her to wake up."

"It won't work," Jem said. "Grace's mind is too well protected. And Yanluo would stop her."

"But-"

"No!" Jem snarled. "I am not putting her in danger!" He'd had enough. Jem marched out, slamming the door behind him. How could Philip think he was willing to put Tessa in danger? Jem ran a hand through his hair. God, what was he going to do? It was like asking him to choose between two people he couldn't live without. But he knew he'd go mad without Grace here, just like he'd never forgive himself if Tessa got hurt while trying to get Grace back. In fact, he was sure Grace herself would hate him for it.

Jem entered his room in a frenzy. He kicked over a chair and threw his jade cane. Thoughts and faces were swirling in his head. Will, Tessa, Grace, Philip.

Will in the ifrit's den. Grace falling away from him. Tessa looking in wonder at St. Paul's. He couldn't make them stop. Did he have to choose? Could he make that choice?

Eventually, things became so much that Jem started sawing on his beloved violin just to block out the noise with something just as painful. That was when Tessa came in, adding to his confusion. He took her in his arms and kissed her, sure she was going to push him away. But she didn't.

By the Angel, what was happening to him?

-*-*-*-*- Grace -*-*-*-*-

She ran.

Grace couldn't do much else than that. Everything was completely out of her control. Yanluo had full manipulation of the plane of her mind. It could so anything it wanted and she couldn't fight it.

Grace sprinted down another corridor, dodging a snarling demon behind her. She rounded the corner but fell straight through a hole in the floor, one that wasn't there before and had appeared just for her. Bracing herself for an impact, Grace closed her eyes...

Whoomph!

She landed on something soft. Opening her eyes, she found herself in an armchair in Philip's room. She blinked. Why would Yanluo take her here? It was dark outside; the stars were shining in the pitch black sky. She could hear the slight breeze whistle past the open window. Everything seemed so peaceful.

Just then, the door opened and Grace herself walked in, followed by Philip. She was dressed in the golden wedding dress that the real Grace was wearing earlier. Philip closed the door and shook off his jacket.

"Your mother really went over board on that party," he said, throwing the jacket onto the chair the real Grace was sitting on. It went right through her like she was a ghost.

"She would do," fake Grace laughed. "She has been looked forward to this day since I was born. But, I'm glad she enjoyed herself, even if she did have a little too much sherry."

"And I'm glad that we can finally be alone," Philip said, coming towards her. He pulled the other Grace towards him, wrapping his arms around her waist. "How does it feel to be Mrs Blackthorn?"

"It feels pretty good," fake Grace said with a smile. Philip leaned down and kissed her, his hands running though her hair. Fake Grace retreated backwards and fell on the bed, pulling Philip down on top of her.

"Or perhaps you would prefer a different fate for Philip Blackthorn,"  the voice of Yanluo whispered in her head. Suddenly, Grace was swallowed up by the armchair, falling through black space again. This time, it was no soft landing. She fell with a thud on hard floor, groaning as she did so.

She pushed herself up painfully, rolling her shoulder. This time, Yanluo had landed her in the middle of the Shanghai training room. Just in front of her, Grace could see a shadowy figure, the darkness literally clinging to them. They seemed to be facing her but she couldn't tell. Suddenly, the figure opened their eyes. They were glowing red, fierce and bright. Grace gasped.

It was her.

The room became illuminated and Grace could see Philip on the floor between her and the evil Grace. Evil Grace was laughing wickedly as she raised her hands. Philip suddenly writhed on the floor. She was causing unbelievable pain to him.

"Grace, please!" he screeched as he thrashed again. "I'm sorry! Please, stop!" Real Grace could see the blood stain on his side where the brand of Yanluo was previously.

"Stop it!" real Grace shouted at her other self. But evil Grace just stood there and smiled.

"Why?" she asked. "He betrayed us. He deserves to feel the pain we feel each day. What is he to us?" Grace drew a short sword that was strapped to her back.

"Stop it right now," Grace said, her voice cold and determined. "Or I swear I will kill you."

"Ha!" evil Grace laughed. "You can't kill part of yourself, Grace."

"You are not me!" Grace yelled. "You are Yanluo, not me!"

"We are one, Grace Carstairs," evil Grace said. "What is part of me, is part of you. The only difference is, you are scared to admit it!"

"No!" Grace shouted. "I am Grace Carstairs and I am nothing like you, Yanluo!" Grace ran forward and plunged the sword straight into her other self, right through her own heart. Evil Grace started laughing manically as she dissolved into nothing.

"I am you, Grace Carstairs," she whispered. "And there is nothing you can do about it." Grace screamed ferociously and yanked her sword back. The room dissolved and she found herself back in the Shanghai Institute, in the East Wing. There was a roar as the demon found her and Grace was forced to run again before it caught up.

-*-*-*-*- Will -*-*-*-*-
"Jem hit me?" Will asked in complete shock. He stumbled back into an armchair. "Jem?"

"Yes, Jem," Tessa said impatiently. "There's no need to keep saying it." They were in the drawing room after Sophie had slapped Gabriel in the training room. It had taken everything in Will not to burst out laughing. But then Gideon had told them the story of his mother and uncle and he was itching to question him about it, but one deadly look from Tessa and he fell silent. Afterwards, Tessa had felt obliged to apologize so Will had followed her, pulling her into the drawing room.

"You really should think about how the things you do affect Jem," Tessa said quietly.

"What do you mean?" Will asked.

"Don't you understand?" Tessa said. "You hurt him Will. You really hurt him when you went to that drug den."

"How does me going to an ifrits den affect Jem?" Will said.

"His whole life has been destroyed by that drug yin fen," Tessa cried. Will could tell she was trying to control her voice. "He can't do half things he wants to do with his life. And then you just decide to drug yourself up like it means nothing! Meanwhile, Jem has to take the foul stuff every day just to stay alive. He does it for you! Don't you see you abused the very thing that is killing him!? The thing that he takes because he knows you won't live without him?"

"He can't think that," Will said, his voice tightening. God, what had he done?

"He does," Tessa said. "He's already having a hard enough time with Grace so ill. He doesn't need you causing him stress too. Don't you care?"

"Of course I care," Will said, leaning forward, elbows on his knees. "It's all I ever think about, Tessa. If people care about me. What they think about me."

"Will Herondale? Caring what other people think?" Tessa said with mock shock. Will forced a small smile.

"Tessa, you have no idea what-" Suddenly, the door opened and Will jumped up from the chair. Charlotte glided in with none other than Wolsey Scott on her arm.

"Oh," Charlotte said. "Will, Tessa, I didn't think you were in here."

"We saw the fire going and decided to warm up a bit," Will said before Tessa could speak.

"Ah, William Herondale, good to see you again," Scott said. "And you must be Tessa Gray. The shape-changing girl, am I correct?"

"Yes," Tessa said, holding out her hand as Scott pressed it to is lips. "A pleasure to meet you."

"And you, of course," Scott replied.

"Will was the Shadowhunter who noticed the werewolves in Whitechapel," Charlotte said, but she didn't say the circumstances in which Will saw this. He was grateful. Charlotte never betrayed her own.

"Just lone wolves, I'm afraid," Scott said. "As far as I know, they don't belong to any pack. Praetor Lupus is looking into it, of course."

"It's strange for Mortmain to target the werewolves," Charlotte said, sitting down in an armchair.

"He's uniting the Downworlders against us," Will said quietly. "Well, tying to anyway. Giving werewolves yin fen probably isn't the best move. So there has to be another reason." Scott studied him with curious eyes.

"How's your parabatai these days?" Wolsey asked. "Lovely boy, such interesting colouring. And extremely talented on the violin."

"He's fine," Will said but he remained wary. "At least, I think so." Scott blinked.

"Such a shame about his illness," Scott continued, eyeing Will carefully. "Odd how the yin fen has different effects on Shadowhunters and werewolves, isn't it?"

"Jem survives because he is a Shadowhunter," Will said stiffly. "And because he takes as little of the drug as infrequently as possible. These werewolves aren't taking it like that." Wolsey nodded to himself.

"You are right, of course," Scott said. Will unclenched his fists. He didn't even know he had tightened them.

"It was nice to meet you, Mr Scott," Tessa said, breaking the awkward silence. "Will and I should be going now." Will turned to walk out of the drawing room, Tessa at his heels.

"Of course, if the yin fen supply ever ran out," Wolsey called, "Then it would prove difficult for you. Wouldn't want to give the Magister any leverage, would we?" Will went taunt. Wasn't that what one of the ifrits said last night? He bolted from the room, not even bothering to pick up a hat and coat, and ran all the way to Whitechapel.

-*-*-*-*- Jem -*-*-*-*-

Jem slid two more seraph blades into his belt then picked up his jade cane. Dressed in gear, he crept from his room, careful not too step on any creaky floorboards. If Will or Charlotte, or even Tessa caught him, they were sure to stop him.

Jem stepped outside, closing the front door and running down the steps. He was going to find Mortmain. He was going to kill him for what he did to his sister. The Clave didn't know where Mortmain was, but Jem had known more than he thought he did.

How did Mortmain create his fortune? Opium. And where did the opium come in? The docks. And the docks had to keep records. Jem was going to find those records and figure out where Mortmain kept his fortune. Take away Mortmain's fortune, and he was exposed. He would be forced to come out of hiding. Then Jem would kill him.

He opened the gates and closed them with a clang. Will would find the note he left. Obviously, Jem didn't tell him where he was going, but he wasn't so cruel to leave him completely in the dark. And anyway, by the time they found out he was missing, he would already know where Mortmain kept all his money. Jem shook his head. He had to focus. Mortmain would tell him how to wake up Grace.

He had to.
