Sweet Little Serena (Rewrite)

Valentine Needs To Make Up His Mind...And Stop Having Kids

The only word Serena could think of to describe the aftermath was devastation. Dozens of Downworld bodies littered the floor of the Institute, and yet, somehow Simon survived the blast.
They were just lucky that the adamas in the walls prevented the heavenly energy from spreading and killing every Downworlder in Manhattan.

But when Alec finally ran into the room, Jace and Serena were long gone.

Clary had explained how she didn't do this and that Jace did, that he had angel blood but to be quite honest, Alec didn't care. He ran from the room to find Magnus and/or Serena, hoping his wife had done as she promised and used her Portal Pendant.

Serena wasn't with Magnus though. She was with Jace outside the Institute, stopping Valentine from killing Luke.

He had been about to bring the Soul Sword down on the wounded alpha when Serena and Jace brought their swords out to block it, pushing Valentine away.

The man managed to disarm Jace, holding his back to his chest and the Soul Sword to his throat. Serena sneered something fierce at Valentine as she threw down her swords, the man knowing that she'd never risk her brother's safety.

Despite there being a few tears, Serena then shed her jacket to cover up Luke, helping him use the sleeve to press down on his wound until his healing abilities kicked in.

"You told me I had demon blood! Why?" Jace asked as he tried to fight Valentine's grip, but the man held him fast.

Valentine met Serena's eyes. "Because that's how the both of you are. Always ready to right the wrong, to stand up to those who can't stand up for themselves, Serena especially. A real-life hero."

"So, you used us? Used Jace?" Serena questioned.

"I just made sure Dot overheard me. That's why I left her behind so you would come and save the day," he answered and Jace fought, Serena taking an anxious step forward before Valentine's gaze pinned her.

"And I activate the sword instead," Jace spat. "You lied. You never injected me with demon blood, it was angel blood! I was always like Serena."

Valentine smiled. "You two are my greatest achievements. I'll admit, the both of you took me by surprise, but you are."

"We're not your achievements! We're your children!" Jace said heartbrokenly, and it reminded Serena of how he used to try and please Michael. Funny how Michael ended up being Valentine.

"No, we're not, Jace," Serena piped up after reading the look on Valentine's face. It only confirmed the theories that she had. "That's why Jocelyn didn't remember me or have anything of mine. I was never her daughter."

"I am not your father," Valentine confirmed, looking at the both of them, Jace unable to see him with the sword at his neck. "I took Jocelyn's memories of her first pregnancy in the hope that she would forget about my experiments. She is not your mother, I am not your father. And Clary... is not your sister."

"More lies!" Jace growled, sword drawing blood from his neck as he struggled.

"Don't I wish," Valentine said. "Truth sword, remember?"

And Jace stilled from shock.

Serena had heard all she needed. And while his attention was on Jace, she pulled a throwing knife from her pocket and wedged it in Valentine's shoulder. Valentine let out a pained groan as Jace was able to break free, catching the sword his twin threw at him as she retrieved the other one and they charged.

They dodged and swiped at Valentine and eventually, as the twins moved in perfect unison, Serena was able to kick the Soul-Sword from his hand.

As the trio fought, they didn't see Clary as she picked up the Soul-Sword and drew a rune on it, deactivating its' heavenly power and burning her hand as she dropped it to the ground.
