Hey guys, just to let you know, this is my first story!
Uhm, I'd also like you to note that I didn't make Clary have the Rune of Quietude on her, and I'm sorry for the constant jump between Jace and Clary's view.
It's fairly short, but I hope you'll enjoy it, and thanks for reading!

(i don't own the characters, just the storyline here.)

"And now," Valentine said, "I just need a bit more," and Clary thought, A bit more what? – Just as he swung the sword back and the starlight exploded off it, and she thought, Of course. It's not just blood he wants, but death. The sword had fed itself on enough blood by now; it probably had a taste for it, just like Valentine himself. Her eyes followed Maellartach's back light as it sliced toward her, only stopping millimetres from her chest as a smile spread across Valentine's face.
Then without warning, the sword plunged into her, as a scream escaped her lips.

It was then that he heard someone cry out in pain, thoughts immediately directing to Clary. What was happening? Was he too late? Various questions and scenarios raced through his mind as he sped up to the source of the sound.

Sprinting as fast as he could manage in his current state, he tried to dispel the thought that any harm had come to Clary. She's fine. She's fine, he repeated to himself over and over, as he began to hear soft murmurs in the distance. He knew he was getting close, and pushed himself further, until he saw what he had feared the most.

As Valentine drew the sword out; Clary gave a small gasp, where red replaced the blade that was once there. The hot liquid spread across her chest, staining her shirt at a rapid rate.

"That was for taking Jocelyn away from me," Valentine spat, as he turned to walk away.
Everything before her began to blur, and with that, she slumped forward onto the sand, thinking of the only one person she wished to see more than anything, before she died.

"Clary? Clary!" She heard, as quick footsteps made their way in her direction.
"Jace?" She managed to whisper, a spasm of fear running through her. "Jace… I–"
"Shh, shh. It's okay. You're going to be okay." He said, as he held her body in his arms, cupping and bringing her face up to his.
"No. You don't understand. Valentine."
"He's not here Clary."
"He must've gone further down the lake to raise Raziel. You have to stop him, you have to –" but before she could finish, she was cut off by a gurgle of blood.

This scene was all too familiar, he thought, as the images flicked before him…

She moved her hands away from her chest and held them out to him. They were sticky with blood. Blood covered the front of her white dress like a scarlet bib.
He caught her with one arm as she sagged forward… her head tilted back, her eyes rolling up to the whites. The wild beating of her heart was slowing – stopping –

He shuddered as he came out of reverie, staring down at the real Clary in his arms.

"Agramon",he whispered quietly to himself, while he took in the state of the Clary before him. The scene he experienced with the demon was no different to the one present, as Clary's entire front was now covered in blood.

"Clary, stay with me," he whispered, while stroking her cheek, "Stay with me. Please."
Clary raised her hand up to his and held it firmly, a small smile playing on her lips. The smile faded as quickly as it had come, as her back arched up slightly. She winced a little, before she murmured something so quiet, that he wasn't sure he heard right – "I love you, Jace. Don't forget that," and before he could respond, her hand fell from his onto the sand. She gave one last shuddering breath, and then nothing.

That's it. He thought; that's it. Clary's gone. It's not possible. Tears pricked at his eyes, and threatened to spill, as he laid her body gently onto the ground. Rage quickly replaced the loss he felt just seconds ago as he got to his feet, determined to finish Valentine for good.

So what did you guys think? I would love to hear your thoughts on this, and thanks again for reading! :)
