CLARY POV:

Clary just stared at her locker in silence. How he managed to do it? She'd never know. The only thing going through her mind, was that her locker was filled entirely with spaghetti.

She heard an equally stunned Simon next to her mutter an "oh no," before she screamed, "JACE HERONDALE!"

When she heard him and his band of merry men laugh in amusement along with everyone else gathered in the corridor, she ran at him, only to be held back by Simon and Izzy. Jace's gang of giggling idiots watched as she let Simon and Izzy drag her away from the scene into an empty classroom.

"How does he do that? How does he constantly get away with stunts like this? How can people actually help him?!" Clary exclaimed in frustration, running her fingers through her fiery red hair, giving up trying to de-spaghetti her chemistry book.

"Does it matter?" Izzy said coolly. One glance at the incredulous look on Clary's face, and the look of warning on Simon's, told Izzy that she should finish quickly. "I mean, Jace will be Jace and keep doing stupid things like this, you know him. But the important question here is, are you going to let him get away with it?"

Clary looked at Izzy consideringly, before answering, "Hell no."

Clary woke at 6am and couldn't get back to sleep. Giving up on her unsuccessful attempts to keep still, she grabbed her IPod and sketchpad, and quietly made her way downstairs and out the front door.

It was still dark, but traces of orange had begun to spill over the horizon like stains of spilt paint in the sky, giving Clary enough light to make her way down the porch steps without falling on her face.

Clary didn't have to think to know where she was going. This had been a constant routine after Jonathan had died. She had woken screaming or crying night after night to horrific visions of the crash burned into the back of her eyes. Clary had needed an escape, so she found herself across the road and at the top of the tallest tower in the playground, with a pencil gripped in her hand, and a page full of incoherent thoughts on her lap.

Clary had stuffed her IPod earphones in and was about to cross the deserted road, when she jumped a mile high as someone clasped their hand over her mouth. Without thinking, she bit down hard on the hand and spun around as the person cried out.

"What the hell, Clary?!"

"What the hell, Jace!" She cried back, picking up her sketchbook and IPod from the kerb which she had dropped when Jace had scared the bejesus out of her. What was he thinking? Idiot.

"I didn't want you to wake the whole street, that's all. You didn't need to bite me."

"And that's the way to not scare me? Wow you really are an idiot," Clary mused.

Clary gave Jace a once-over. He was dressed in what appeared to be jogging clothes; a grey muscle singlet, baggy running shorts and black sneakers. Clary suddenly realised she was still in her pajamas and quickly crossed her arms, hugging her sketchpad to her to hide winnie the pooh and piglet.

Jace stood glowering at her, which slowly turned into a smirk, "So how did you like the present I left in your locker?"

If Clary wasn't mad before, she definitely was now.

"I loved it, thanks a lot, Jace! You really know how to treat a girl. Kaelie really is lucky to have you." Clary said, her voice dripping with sarcasm.

"I actually got the inspiration of spaghetti from-"

"All I heard was, 'Blah blah blah, I'm an asshole,'" Clary cut in. "I really don't care, Jace."

Jace stared intensely at Clary's face for a moment before taking a step closer, and smiled smugly before saying: "You know, Red, I honestly expected more from you. Retaliation. I thought you would've wanted the last laugh."

Although Clary was tempted to take a step back she stood her ground and smirked up at Jace, "That sounds like a challenge, Goldilocks."

"That's because it was." Jace replied, before spinning around and jogging down the stil deserted road, leaving Clary hugging her sketchpad and staring after him in irritation.

Izzy: The eagle has left the nest, we're a go.

Clary: Let me grab my supplies, I'll be there in five.

Clary put her phone down and watched from her window as Jace left his house and started jogging down the street. She waited for him to go around the corner before quickly walking outside to meet up with Izzy in front of Jace's car. It had been two days since Jace had snuck up on Clary during her early morning escape, and Clary had been waiting for the perfect moment to get her revenge.

"Okay, we've got thirty minutes tops until Jace comes back from his morning run, let's get cracking." Izzy said with a grin as she Clary walk towards her with her arms overflowing with post it notes.

Clary and Izzy spent the next twenty minutes frantically covering Jace's entire car with post it notes. Once they were satisfied with the now hot pink and purple post-it covered car, Clary brought out a black marker and wrote across the post-it notes: 'How's this for retaliation?'

Five minutes later Clary was quietly sketching in her notebook until she got interrupted by a loud, masculine scream, followed by a string of curse words. Clary grinned to herself. She did like getting the last laugh.

Clary slumped into her room, exhausted. It had been a long day, and it was made longer by the fact that everywhere she turned she had been expecting another prank from Jace and his minions.

All Clary wanted to do was sleep. Then she remembered the art project and the work she was way, way behind on. Art was Clary's best subject, but for once she was behind everyone else. While they were all drafting their art boards, getting approval and feedback from Armatis, Clary's pencil was hovering midair, a pile of discarded pages in front of her.

With hope to have late night inspiration, Clary pulled out her sketch pad from her bag, and turned her lamp on. She did a double take and felt her heart miss a beat. Clary didn't even realise she was screaming until Jocelyn burst through the door on high alert.

"What is it?! What's happened?" Jocelyn asked, looking around Clary's room in alarm. Clary pointed to her lamp, shakily, but it wasn't the lamp that had Clary worked up, it was the silhouette of a humongous and disgusting looking spider on the inside of the shade. She watched as Jocelyn moved towards it and quickly pulled the lamp shade off. They both squealed slightly when the big black shape fluttered the carpet at their feet. Clary sent a slightly panicked look in Jocelyn's direction, while Jocelyn leaned over to look at the bug.

"What are you doing?" Clary screeched in panic as Jocelyn picked the monster up. A flash of amusement danced across Jocelyn's face as Clary looked cautiously at what was in Jocelyn's hands. Clary immediately felt foolish when she saw that it was a black piece of paper cut into the shape of a spider. Jocelyn chuckled as Clary turned red.

"Goodnight, Clary. Don't stay up too late," Jocelyn pressed, eyeing the sketchpad Clary realised she was still had clutched tight to her chest.

"Night, Mum. I'm just going to go to sleep, not in a drawing mood anyway."

Jocelyn frowned at this, as if wondering if something was wrong, but didn't press any further and gently shut the bedroom door behind her.

Clary sighed and collapsed, sprawled out on her bed. Stupid Jace and his stupid prank. She was going to get him back if it was the last thing she ever did.

Bleep.

Clary dug in her pocket for her phone and pulled it out. It was a text alert. Oh, no.

Sleep tight, don't let the bedbugs bite. ~Jace ;)

Bedbugs? But the spider was on her lamp…

Clary tore off her blankets in a sudden panic and tried to muffle the instinctive scream that rose in her throat.

Her bed was filled with plastic bugs.

"Jace is gonna freak when he sees this." Izzy chuckled as she put another pair of Jace's (thankfully clean) underwear into the vending machine.

After an hour of rummaging through Jace's room grabbing whatever they could get their hands on, Maia, Izzy, Simon, Jordan, Magnus, Tessa, and Clary, had all gathered inside the school. If someone walked into the school now they all would've looked incredibly guilty - which they were. The whole group was here to help Clary pull off her next prank on Jace. Magnus had somehow gotten the key to all of the schools vending machines (Clary knew better than to ask how), so now they were all stuffing items from Jace's room into each vending machine around the school.

"This feels wrong," Tessa said, munching on another chocolate bar that she had swiped from the vending machine.

"Ha, speak for yourself," Simon replied while trying to stuff one of Jace's sneakers into the machine, "This is justice."

Tessa scoffed and raised her eyebrows, but before she could say anything Simon tossed another packet of stolen chips in her direction.

Once they had finished tossing Jace's stuff into the third school vending machine, they decided it was time to call it a job well done. Okay, that's not exactly how it happened. Magnus was helping Clary shut the vending machine (it was practically overflowing with Jace's stuff), and they heard a shout from the school elderly janitor. That's when they all decided to make like a banana and split.

Clary was greeted by an irritated Jace the next day. Although Clary was severely sleep deprived, and incredibly nervous about getting caught, the sight of a pissed off Jace could always make her day.

"Do you realise how long it took for me to grab everything from those vending machines?" Jace cried out. "Not to mention all the stuff I had to take back from girls, who wanted my things as keepsakes."

"Well hello to you too, Jace." Clary replied with a cheshire cat grin.
