Isabelle walked into the Institute with a new sense of purpose. She was going to get her brother's happiness back, and she would do that no matter the cost.

She walked up to the door of Alec's room. She noted happily that she could no longer hear the raging sobs from outside the door.

She started knocking softly as to not startle her brother.

"Alec, come on, let me in," she knocked again.

And again.

And again.

Her knocks, along with her voice, grew frantic and hurried.

"ALEC! LET ME IN!" her breathing ragged, she turned and ran down the hall to Jace's room.

She was so scared that he'd done it again. He'd tried to kill himself again.

She threw the door open, not caring that she'd caught Clary and Jace in the middle of a quickly escalating make out session.

"Jace, help, it's Alec."

Jace felt his blood run cold at the sentence. He jumped out of bed, Clary in tow.

Jace started banging on the door harder than Isabelle and Clary ever thought possible.

Clary, bless her, pushed Jace out of the way seeing her was getting nowhere.

Jace was livid. He didn't care that it was Clary that pushed him away. Anyone who tried to keep him from his brother, his parabatai, was going to get it.

Clary pulled out her stele, working in hurried motions to draw the 'unlock' rune on the door.

She heard the click of the lock and pushed the door open.

Jace and Isabelle sprinted into the room, Jace stopping only to kiss Clary's forehead in thanks and relief.

As Isabelle entered the room, she was devastated, but not surprised, to find Alec with scars split open on the bathroom floor.

Her tears cascaded down in a torrent.

"Jace, come draw the rune! NOW!" she screamed in fear of losing he last real brother.

Sure, Jace was like a brother and she loved him the way a sister loves a brother, but Alec was the only one left that shared her parents. Her blood.

"We can't lose another brother, Jace. We can't," her voice came broken with sobs.

Alec wasn't awake, but his blood was pouring out of his wrist in gushes.

Jace cringed at the sight, but quickly drew the iratze on Alec's chest.

They waited a beat. Nothing happened.

The wounds weren't healing. The blood wasn't even slowing down.

Isabelle became frantic.

"JACE IT'S NOT WORKING! CALL MAGNUS!"

Jace wasted no time in seeing to Isabelle's instructions.

He sent a fire message to the warlock basically demanding that he come tend to Alec no matter what happened between them.

Jace looked down at his brother, feeling his eyes prick with tears for the first time in years.

He couldn't lose Alec. Not now, not ever.

He waited in silent panic for the warlock to show.

5 minutes later, Magnus came barreling down the hallway to his shadowhunter's room.

He stopped abruptly in front of the doorframe of Alec's room.

He ran to the huddle of people crouched in the floor.

"Out of the way," he tried to keep the brokenness out of his voice.

He crouched down to Alec, taking his mauled wrist in his hand.

By this time, Jace and Isabelle had, for the most part, got the cuts to stop bleeding but the amount of blood Alec already lost was alarming.

"Oh Alec…" he whispered and leaned down to kiss the sickly pale forehead of his love.

"Get him on the bed," he commanded, his voice hard.

Jace and Isabelle obeyed silently, hoisting Alec onto his small, rectangular bed.

Magnus rolled up the sleeves on the sweater he was wearing. Alec's sweater.

Magnus took in the appearance of the dying boy, feeling tears prick the back of his eyes.

He pinched the bridge of his nose and forced the tears back.

There was no time for tears. He was going to save Alec.

It was either save him or join him and Magnus was dead set on the former.

"Alright, everyone out."

They all shuffled out albeit unwillingly.

He heard the door close behind him and he took this moment to sweep the black locks back out of Alec's eyes.

He leaned down and kissed the boy's cheek, feeling the tears return.

"I'll save you Alec, I swear."
