The demon loomed over Jace and he could hear Clary screaming in Simons arms behind him. The dagger it held plunged towards him. Straight for his heart, a blow that would surely kill him. He didn't move to resist, this was for the best. For everyone, for Clary. They were better off without him.

His eyes fluttered shut, waiting for the pain, but it never came. He opened his eyes.

A woman stood in front of him. Blood was blooming from a wound in her chest. She coughed blood and fell to her knees as Jace stood over her in shock. She reached a hand up and grabbed at his shirt. He wasn't aware of Alec and Magnus running into the room. Not even aware of Alec sending an two arrows through the demons eyes and one through its neck. He fell beside the brown haired girl. She was on her back, gasping for air. She set her grey eyes on his golden ones and recognition passed through them. "Jonathan." She laid her hand on his cheek and let out a sob. "You're so beautiful."

Jace stuttered "H-how-?"

A yell behind drew his attention away from the familiar girl. "TESSA!" It was Magnus. He was sprinting for the two people crying on the ground. Jace didn't know why he was crying. He just felt a terrible sadness. Magnus dropped to his knees beside her. Tears were running down his face "Tessa, oh Tessa."

Her voice was croaky when she talked. "Magnus, my dear old friend. It has been so long."

"You can't leave, Tessa, what about Jem?!"

"Tell him I am sorry. And that he will join me soon." She choked on her tears.

"And what of me? I only just found you again." Jace hadn't ever seen Magnus lose control of his emotions like this.

"You will be fine without me." Her voice was lowering. "It's okay Magnus, I'm going to see Will. He has waited long enough. Goodbye, for now..."

Her breath escaped in a rush and she closed her eyes.

The girl called Tessa was gone.

She was smiling.

They watched, sobbing, as her body slowly crumbled away into ash.
