Before Clary could think Sebastian had grabbed her and dragged her into the circle.
"So little sister, you couldn't stay away could you?" Sebastian said smoothly.
"I need to protect the ones I love." Clary said acidly. "I'm not letting you take my family from me."
"Including me?" Her son said stepping towards her.
Clary looked up at him. He looked just like Sebastian, down to the darkness in his eyes. Now she knew exactly what her mother must have felt when she looked down at Sebastian.
"Yes," She said quietly. "Including you."
"How can you say that mother?" He spat. "When you do not even know my name."
"Because I know you, I knew you before you were born. Before you were turned to the darkness by your father. I knew your heartbeat, your kicks. You are a part of me, and you know me as well as I know you. So if you wish, you may tell me your name. But your name to me will always be son."
He stood there slack jawed staring at Clary, unable to speak for a long time. Then he drew in a deep breath and said. "M-my name is Jonathan Valentine Morganstern."
"Nice to meet you Jonathan," Clary said. "I am sorry we are meeting in such dire circumstances."
"That's enough she devil." Sebastian spat grabbing her around the throat.
Clary felt the tip of a knife at the edge of her chin. "S-Sebastian, you're hurting me."
"You are trying to steal my son from me." He hissed. "Just as our mother stole you from me."
"Valentine did that," Clary gasped fighting against his iron grip. "Mom had nothing to do with it. He took you from her and made her believe that you both were dead."
"She was my mother." He said quietly. "She should have sensed I was alive."
"How can she sense anything when she was shunned by her own kind." Clary said.
"Father!" Jonathan yelled.
But he was too late, as quick as a flash Clary had drawn a strange looking dagger. She drove it through her chest and out her back into Sebastian's chest. The Forsaken began to converge on their fallen master. Clary saw one of them grab Jonathan by the neck as two more began to advance on him. In the distance she heard Jace screaming her name as she fell into darkness.
