Magnus rolled over onto his side, arm reaching out subconsciously for his warm, naked boyfriend. He groaned in frustration when the palm of his hand met silky sheets instead of warm skin.

"Alec, come here," Magnus mumbled against the pillow, scrunching his face up in irritation when no response followed. He made impatient grabby hands towards the spot Alec usually lay and waited for a muffled giggle or annoyed grunt. He was surprised when nothing but the sounds of Chairmen Meows snores answered him. He slowly peeled his eyes open and lay, a little hurt, for a moment. "Freaking Shadowhunters and their early mornings…" Magnus mumbled incoherently under his breath as he got himself out of bed and dressed in a pair of sweat pants and a t-shirt. "Alec? Where are you?" He bellowed softly, shuffling into the kitchen hoping to find Alec there behind the stove cooking him some delicious breakfast.

Magnus let out an exaggerated sigh when he again came up empty. Now, in a more than grumpy mood he began the task of making his own breakfast, without a hot boyfriend to watch him do the task. He means to put a lot of emphasis on that point.

"Alec did you seriously leave me here all alone on a Saturday?" He yelled loud enough to wake neighbours, if he had any.

The simple fact that Alec had left him all alone on one of their only off days ruined his whole day. He knew, inside, that Alec had to do what Alec had to do, he was in fact a Shadowhunter, but he was still allowed to be pissed off. He wasn't even angry with Alec, just with the whole Shadowhunter race for taking away his Saturday. He made a mental note to yell at Jace for it later.

Once he was done with breakfast he sat down on his big leather couch and turned on the Tv. He pulled out his cell phone as he flicked through the channels. He waited patiently as the phone rang, and rang. Magnus was sure his heart stopped in that moment when he could here from somewhere in the house Alec's phone going off. He quickly got to his feet and scrambled through the house looking for the freaking thing. He found it, lodged under Alec's pillow. As he held it in his hand he wasn't sure what he felt, worry? Pity, because maybe Alec just forgot it and it was all just some misunderstanding? Or confusion? It was a little bit of everything.

So, as quickly as he could he opened Alec's phone and dialled Isabelle's number. With every ring Magnus's heart beat faster.

"Hello?" A male voice answered, mouth filled with food (he hoped).

"Who the hell is this?" Magnus roared, his temper rising as the minutes progressed.

"This is Simon, who is this?" Simon apparently, asked.

A feminine voice, Isabelle's, shouted something in the background, "I have caller ID you dipshit!"

He heard a shuffling noise a button being pressed and then Simon's voice replied, "Yeah this isn't Alec, is this Magnus?"

"Yes, would you put your girlfriend on the phone already, Sherlock."

"It's Simon."

"Yeah, yeah," Magnus waved his hands up in irritation.

There was more shuffling noises and then Isabelle's voice came through the phone, "Magnus? Why are you on Alec's phone?"

"Isabelle I was wondering if Alec was with you or Jace, or if you happen to know where he might be?" Magnus stopped sounding angry as nerves took over his body.

"Uh, no, he was supposed to be with you all day, Magnus, he was super stoked to be staying the whole weekend at your place. He wouldn't have let anything ruin that." There was a silence that passed between the two. "Magnus?"

"He's not here Isabelle." Magnus whispered, fear finally bubbling to the surface.

"What?" Isabelle's voice came out a little panicked and shaken up.

"He's not here. I woke up and he wasn't in bed and he's not in any other room I checked every where believe me when I say that."

"Okay, let's not panic just yet. Call Jace first maybe he needed Alec for something. You know Alec he'd do anything for his parabatai."

"What just happened to, 'he was super stoked to be staying the whole weekend at your place. He wouldn't have let anything ruin that'?"

"Maybe I just said that so you'd go away."

"Oh how nice, I'll call you if I find him, if I don't I'll call you anyway." With that being said he hung up the phone and quickly dialled Jace's number.

"Hello?" Jace's voice came through the speaker sounding out of breath.

"Jace? This is Magnus."

"Oh, how nice to speak to you Magnus what can I help you with?" Jace's smirk was obvious through the line, it took everything in him not to go over there and punch Jace in the face. Magnus didn't know why that upset him so much.

"Are you at the Institute?" Magnus quickly asked.

"Yes? Why are you asking? Do you miss me that much you wanna come visit?"

"You really do like hearing yourself talk. Is Alec there?"

"No, why?" Jace's voice suddenly got serious and he could tell something was very wrong.

"He's not with me, he was here last night but I woke up and he was gone."

"I got a bad feeling last night, right where the Mark is, like something was very wrong."

"Why didn't you say anything sooner?" Magnus screamed into the receiver of the phone.

"I figured he'd be okay, he was with you!" Jace yelled back almost as loudly.

Magnus growled raking a hand through his hair in frustration, "Call Isabelle, tell her to get to the Institute as quickly as possible and tell Maryse, I'll be there in a minute."

He hung up quickly shoved both cellphones into his pocket and turned to face the wall. Without a seconds thought he began to summon a portal to the Institute.

God, he hoped Alec was okay and this was all some big, big misunderstanding.
