Jace POV

Magnus and Will made their way back inside and sat back down. Will was glaring at me from across the table like I had just murdered his cat.

"Okay," Magnus clapped his hands together. "What are the rules for this bet?"

"Rules?" I asked.

"Yes rules Jace."

"Why?"

"Well the bet is to stay with someone for a month that the other person chose and if you can't take a month then you have to be the others 'slave'. For instance if you can't stand spending a month with Will here," he said gesturing to Will sat, still glaring at me." Then you have to be my 'slave', correct."

"Yeah I know that."

"I haven't finished yet. So you could just go back to the Institute with Will and hardly see each other, now that's not spending a month with someone. So I'm implying that we make some rules."

"Like what?"

Magnus thought for a moment. "You have to always be within 10 meters of each other and when in the Institute you have to always be in the same room no matter what. Same goes for Simon and I at my place." He finished looking at me.

"Sure." I said. How would he know if I wasn't in the same room as Will or within 10 meters of him?

"Now just to make sure that you follow the rules I will put a charm on the two of you so when you do break the rule handcuffs will appear. One end around your wrist," he said pointing to me. "and the other end around yours" he said pointing to Will. "That will only last a day before the handcuffs disappear. Now give me your hands." He said to Will and I. I started at Magnus and he raised his eyebrows at me, waiting. Clary nudged me and I reluctantly gave him my hand. He then looked at Will who rolled his eyes and gave Magnus his hand too. Blue light passed over our hands and I felt a strange tingling sensation going up my arm. But just as quickly as it had come it vanished along with the blue light.

Magnus then did it to himself and Simon. "The charm will break in a month. Now come along Simon we're leaving." Magnus said standing up. Simon rolled his eyes and followed Magnus out the door.

"Well who's ready to order?" I asked.

-Line Break-

After dinner we made our way back to the Institute. I didn't believe that the 'charm' Magnus did to Will and I would actually work. But just in case I always made sure that we were in the same room.

I turned to Will. "Well I guess we have to share the same room."

"Urg" Will groaned following me to my room.

I opened the door and walked in. "Well then you can sleep here," I said gesturing to the floor. "Until we get another bed in here."

"Nope, not gonna happen goldilocks," I scowled. "I believe that I am the guest here so I will have the bed."

"Not gonna happen."

"It's polite to allow your guest the bed."

"I don't care."

"Are all Americans this rude?" he smirked at me.

"Only the good ones." I smirked back at him.

"What is it with you fake blondes?"

"I'm a natural blonde."

Will ignored me and walked over to my bed. He laid down on it and put his arms behind his head. "Sorry mate looks like the beds mine for the night." He sighed and closed his eyes.

I finally had enough. I couldn't stand him. He had only been here for a few hours and I couldn't take it anymore. I lunged at him and tackled him to the floor. He grunted, his head banging against the floor. He shoved me off him and kicked me in the stomach. I grunted and punched his arm. I got up and so did he, I pushed him against the wall. He pushed me back and I kicked him. He laughed. What the hell? I was so surprised that I didn't realize that he had walked back over to the bed and sat down on it again. With a growl I tackled him down on the bed and push him into the headboard. He smirks up at me.

"Mate come on, I'm pretty sure it's illegal to shake the bed with a relative."

I punched his face and sat back, but he jumped back above me and kneed me in the gut. I groaned and kicked him up off me, tackling him again to the ground. I pinned him down and punched his face, but with his knee he hit my back. I let out a noise of surprise, and at that moment Clary comes charging in the door.

"By the angel, what is going on in here?"

"Will was-"

"Please mate, we all know that the only one with a problem in this room is the fake blond."
I punched him again in the face, braking his lip and causing blood to trickle down.

"Jace!" Clary screamed, "Get off him!"

I rolled my eyes and stood up, lying back on the bed and grinning at her. She glared at me.

"Jace get the hell off that bed."

"But Clary, it's my bed."

She raised her eyebrows, being unable to raise one. Will laughs, "Sweetheart, I'm pretty sure it's more effective with just one eyebrow raised."

Clary turned her glare to Will. "You're not getting the bed either."

"That's fine, I was never really fussed anyway. A bed would be nice but not a necessity. I like seeing your boyfriend all fired up. It's humorous."

"Can I take the bed then? Since Will doesn't want it?"

"Hell no. Your both on the floor, I'm on the bed."

"Clary come on, we can both have the bed!"

"You and Will?"

"No, you and me."

"No way, Will doesn't have that option does he?"

Will smirked from the floor still. "I wouldn't mind sharing the bed with you babe."

I went to lunge at him again but Clary got in between and kissed me, effectively distracting me. She pulled away after a moment. "Good, get on the floor, I'm on the bed. No arguments."

I groaned and sat on the floor, pulling my doona with me.

"Jace don't be an idiot, you wouldn't want me to get cold would you?"

We had a staring competition, which she won and I reluctantly gave her the doona.

Will stared in shock, "Never thought I would see a Herondale so whipped."

I glare at him and punch his arm. He laughs again and sits up, stretching out his arms as he does so.

"Come on Jacey, let's go get some bedding, so we can snuggle during the night!" Will says with a sarcastic clap of his hands." I glare at him and walk out the door, him hot on my heels. I walk through the institute until I come to the supply room, where I grab out sheets, a pillow and an inflatable mattress. I tuck it all under my arm and Will follows my lead, and we walk back to my room where we set it all up. I walk in and Clary's sitting on my bed cross legged and drawing. I smile and sit down behind her, kissing her neck. Her sketchbook lays forgotten beside her and I can feel her laughing.

"Jace, your still sleeping on the floor." I pull away and lie down on my bed in silence, Will's laughter echoing around the room.

"Good evening lady and gentleman, pleasure making your acquaintance this evening." I roll my eyes and rolled over to face the wall, pulling my blanket with me.

Clary POV

I tossed and turned that night, trying to warm up but unable to during to the lack of body heat. I finally fell asleep, but it scared me how much I relied on Jace for warmth and safety. Somewhere in the middle of the night, I felt the bed dip down and Jace climb in behind me, so I snuggled into his familiar warmth, his hand resting on my hip. I felt as though I should be annoyed at him, but I couldn't bring myself to be so I let him stay.

I woke up in the morning, and felt so warm; warmer than usual, but I didn't complain and snuggled further into Jace's chest. I felt him stir behind me and pulled me closer to his chest. I opened my eyes to see Jaces gold ones staring at me from where he was standing beside the bed.

"What the hell is going on?"

I look up shocked, why was there two Jace's? Unless, I turn around, when I realize with horror that it must be Will behind me. I turn to find his dark blue eyes staring intently into my green ones, a smirk playing around his lips. "Good morning Sweet Heart."

"What the hell?!" I yelled jumping out of the bed.

"Clary why were you in bed with him?" Jace's voice was deadly quiet.

"Jace listen to me, I thought he was you that's why I let him stay."

"Oh okay so you're saying that it would've been okay for Jace to have the bed and not me? I am wounded, truly I am wounded." Will mocked a hurt expression.

"You stay out of it." Jace turned to Will.

"Oh I am so scared, what are you going to do about it Goldie-locks?"

Jace didn't say anything. I could see that Will was really pissing him off but he was trying to control himself, he didn't want to lose the bet to Magnus.

"Jace I'm sorry." I said kissing him on the mouth. To my pleasure and relief he kissed me back.

It was all good until Will opened his mouth again. "Is it my turn now?" Jace pulled away and glared at Will who just smirked at him. Jace turned on his heel and stormed out of the room.

"Look what you've done now." I turned to Will.

"This is your fault as much as it is mine."

"If you had just kept your mouth shut-" I was interrupted by Jace being dragged back into the room as if by an invisible force. He stopped next to Will and handcuffs appeared around Jace's right wrist and Wills left. Will laughed while Jace looked like he was about to murder someone, probably Will.

"Magnus wasn't kidding." Jace mumbled.

At that moment Izzy and Alec came running into the room. "Guys there is a demon attack over near the Hudson River." Alec said already with his gear on.

Jace held up his cuffed wrist. "Little busy right now, I'm sure you guys can handle it by yourselves."

"We need everyone we can get and it's not my problem that you didn't listen to Magnus. Now come on get your gear on and let's go."

A/N- Hey guys sorry about the long wait, kinda hard when you are writing it with someone else. Anyway here is chapter 5, what do you think? Tessa and Jem will come into it soon but don't expect any Jessa because we are mainly focusing on Will.

Please continue to R&R
