"Alec?" Isabelle poked her head around the door, hoping she'd heard Magnus correctly. The warlock had been muttering, staring the floor. She was sure he'd been crying.

The dark-haired boy in the bed focused his eyes on Isabelle.

There was a beat and "Izzy!"

Isabelle broke out in a smile. The way Magnus was acting you'd think Alec was on his deathbed.

But why did he say 'Don't mention me.'?

"Are you okay?" she rushed forward and held her brother face in her hands.

Alec laughed and pulled back. "I'm fine. What happened?"

Izzy frowned slightly. "You don't remember?"

Alec shrugged. "It's kinda weird. This guy wandered in, looked at me like I had two heads when I asked if he was doctor, then rand out. I could've sworn I known him."

Isabelle felt herself go pale. Her heart felt like it shattered. Oh.

"Magnus?"

"Who?"

"Magnus Bane? Warlock?" she almost said boyfriend. Her hand began to drift towards the panic button.

"Warlock? Warlocks don't exist Izzy. They're in fairytales."

"Is this a joke? You don't know who Magnus is? Simon? Luke? Jocelyn?" her heart went cold. "Jace? Clary?"

Alec's frown deepened. "I know Jace and Clary. And Simon. Who're the rest?"

Her hand hit the panic button hard.

XXXxxxXXX

"Pick up you stupid magical arsehole." Isabelle muttered as she paced back and forth in front of the hospital.

The doctor had diagnosed Alec with memory loss. He could only remember parts of the last year, Luke and Jocelyn and Magnus and Maia and Sebastian and Valetine being wiped from his memory.

After extensive questioning on Clary and Jace's part and a very bewildered Alec, they figured that Alec had completely forgotten pretty much everything to do with Shadowhunting.

His brain filled in the blanks: his parents would go on long work trips together, Jace and Clary had met at a club. The only thing he hadn't edited in his brain was Magnus. He'd just blipped him out entirely.

Isabelle had told the others not to mention him, mostly on Magnus' wishes and she wanted to bash his brains in for not trying to help Alec's memories.

After leaving several voicemails, which got progressively aggressive and violent, she wandered back into the hospital.

Jace was talking to a doctor. She stepped up behind him and listened to them.

"We'll send him home with you." the doctor was saying, "If he sees familiar surroundings he may remember?"

Jace nodded, his shoulder slumped, his blonde mane dropping. Isabelle forgot how close the two were. It would weigh more on him, Jace was there. He watched his Parabatai be swallowed under a car. Heard the bones crack, the screams from Alec and passers-by.

Had he seen it coming? Had he reached out for Alec just as he went down? If he'd been faster, would Alec be okay?

Isabelle shook her head and left Jace to sort out the technicalities.

She went back outside, desperately trying to reach Magnus.

Finally he picked up.

"What Isabelle?" he sounded like he'd been crying, his voice weary.

"We're bringing Alec home. The doctor thinks he may regain some memories if he's in a familiar place."

"Why are you telling me?"

"He will remember, Magnus. If you hide from him, he'll never remember and you'll never get him back."

"I can't even magic him well!" Magnus exploded suddenly. "It's a mundane problem and magic won't help it!" he seemed on the edge of hysterics and as he spoke, there was a crash followed by yowling.

"Are you researching it?" Isabelle asked.

"No! Yes! It won't help him."

"Do you want to go to the Institute and we'll meet you there? We'll reintroduce you and when he remembers you can get married and adopt a kid."

"It's better off if he doesn't know me."

"Mag-" Isabelle was cut off by a bleep. The warlock had hung up on her.

She tried and tried to call him back, left him voicemail after voicemail, until Alec was wheeled out in a wheelchair, the small group of teenagers behind him.

Alec didn't remember anything, back at the Institute.
