Just so you know, this is after City of Heavenly Fire. Enjoy!

Alec crept thought the institute. He had silence runes on and his hair underneath a black beanie. Pink hair isn't good when you want to be stealthy.

The sun wasn't due to rise for a couple of hours. Since he was always the first awake he thought now would be the best bet for everyone sleeping.

"Did you just get back from Magnus's?"

Alec whirled around to see Izzy smirking at him from the kitchen. "Uh...yes." When Izzy's smirk grew he waved his arms. "No! I mean I did, but we didn-"

"You guys didn't" Izzy's eyes sparked "how'd he put it? Canoodle?"

"No! Not that time. I mean-" Alec was extremely embarrassed. His face had gone past the tomato stage.

Isabelle cocked her head. "So you guys have done it?" She asked casually.

Alec took a deep breath and gathered himself. He pointed an angry finger at his sister. "That is none of your business. And what are you doing!" He desperately searched for something to accuse her of. "Having a midnight snack! That is unhealthy!" With that he practically ran away.

By the time his face returned to a normal color he had made it to Clary's room.

Slowly, he opened the door and let his eyes adjust. Clary was indeed sleeping. His eyes scanned the rest of the room before finding his target on the nightstand. Her stele.

He walked over and gave Clary a cautious look. At least she didn't drool in her sleep.

Grabbing the stele he pulled out the bottle of glue. Magnus had enchanted it so nothing would be able to take it off. Frowning in concentration, Alec poured glue over the handle of the stele, not even surprised that it was glitter glue also.

Then he placed it into Clary's hand. She unconsciously grabbed it in her sleep and he sneaked out. Mission accomplished.

"Ahhhh!"

Simon started and looked around the kitchen wildly. "What was that?" He looked to Izzy who only shrugged

noncommittally. Guess random bellows of rage were common here.

He jumped again when Clary burst into the room. Izzy glanced over at him. "We need to work on your nerves."

"Look at this!" Clary yelled, waving her stele around.

"Ah yes, a stele. I know that one." Simon said.

"No! It's glued to my hand!"

Simon looked closer. It did seem to be awfully attached to her hand. "I'm new to this but I don't think that's how it's supposed to work."

"It's not." Clary exclaimed. "And it's glittery!"

"It'll be the new thing in Shadowhunter fashion. Magnus will be proud." Izzy stated.

Clary's eyes narrowed. "Magnus. And Alec. When I find them I'm going to lovingly smack them. Where's Jace? I need his help."

"I don't think Jace is the lovingly smacking type. More like 'look at me, I will defeat you all through the power of my abs and with my eyes closed' kinda thing." Simon said. When Izzy and Clary just stared at him he put his hands up. "From a very heterosexual point of view of course."

"Well. You do have a conveniently placed weapon to hit them on the head with." Izzy observed.

"Indeed." Clary said and then swung out the door. She wasn't going to let them off easy.
