Clace - TMI AU

She saw him stir and stared in horror. She couldn't believe it had actually worked.
"Jonathan." Croaked Valentine. Her brother threw her aside and ran to his father, pulling him into a sitting position. She watched her father and brother as they reunited. Valentine eventually looked over at her, "Jocelyn?"
"No that's your daughter, my sister. Clarissa."
"Clarissa, my daughter, thank you."
"I am not your daughter, you're a monster." She spat at him. A murderous look flashed across Jonathan's face. At that very moment the doors flew open and several shadowhunter flooded the room. Clary looked around and saw her family, Alec and Magnus and Isabelle. She sobbed a breath of relief. "No! How did they find us? You're not fully recovered yet, they can still kill you without harming Clary." Hissed Jonathan. Clary sucked in a breath. No one else seemed to have heard.
"You're under arrest by the order of the Clave." Boomed Alec.
"Like we'd ever surrender to you." Shouted Jonathan. "Nice to see your recovered Isabelle, no hard feelings?" He mocked.
"Don't mock me you son of a bitch."
"I should've killed you when I had the chance." He said before lunging at her. Clary heard someone call her name and felt a hand on her arm. She turned to see Jace crouched next to her and dread filled her body again. Here she was defenceless. She flinched away from him. "No, no get away from me. Alec help!" She screamed. Alec ran to her side as a confused and a hurt Jace backed away.
"What is it? Clary are you okay? Why won't you let Jace help you?"
"He hurt me." She whispered, utterly broken.
Alec turned to Jace, "Go help Magnus and Izzy, I've got this." Jace nodded, his brows were furrowed. He looked grieved as he turned to help Izzy.
"Clary what happened?" He said inspecting her wrists and applying an Iratze. "Tell me everything."
She could hear the other fighting around her.
"There's no time. You have to help the others. But leave me a weapon. If we wait too long then Valentine will become bound to me and you'll have to kill both of us." She said groggily. Alec nodded, left her a kindijal and ran to help the others. Sebastian was stronger and faster than any other shadowhunter she'd ever known. Especially with Jace on his side. She did a double take. Two Jace's. How could there be. She watched as one of the Jace's warped and changed into a demon. She stared in utter shock. He'd made her think Jace was doing those horrible things to her when really it was a demon the entire time. She felt slightly ashamed. Shocked and ashamed. How could she have mistaken him for a demon. It occurred to her that Jonathan had also managed to find a demon to obey him as well as a warlock. They were almost too powerful for Alexander and the rest to beat. Clary turned her attention away from her family and focused on Valentine. She had to stop him from fully coming back to life before it was too late. Nothing else mattered at the moment.  She got up dragged herself over to a wall that Valentine was propped up against. He opened his eyes and saw her coming towards her.
"Clarissa, what are you doing?" He asked her in alarm. She ignored his question and hauled herself forward. He pulled himself to his feet.
"I can't let you live. You've caused too much havoc, killed too many people." She lunged towards him but he sidestepped. They were both as weak as each other.
"You'll die too. You're so young. You don't deserve to die, you deserve to live and long and fulfilled life, unlike I did. Mine ended too early. The same can't happen to you."
"I'll get over it." She remarked and lunged at him again. He dodged it and his out at her, punching her stomach. She doubled over and felt another blow in her shoulder making her stumble. She regain her her balance as Valentine advanced on her. She gripped the knife in one hand and held her stomach with the other. Valentine brought his hand back and she kicked her leg up as hard as she could straight into his groin. He screamed in pain and she took the opportunity to plunge the knife into his heart. She felt a sharp pain in her own chest, the same place she'd stabbed him and fell to the ground as the world around her turned black.
