"Whispers stop it" Alec said looking at her. 

Whispers looked at him from her bag. "Alexander you can't stop me. This is not my choice." Whispers said loudly. 

Her name Whispers made no sense but Alec called her since she met him before she used to only whisper. She was going to Idris because of Maryse, Alec's mother and Whispers adoptive mother, to be a weapon specialist. She had been creating weapons and the Clave had taken interest in her gift. 

"I can stop you. Will you be my Parabatai?" Alec said looking her dead in the eyes holding her hand causing Whispers to go into shock.

 Maryse had walk in on this comment. "No she can not Alexander. She is leaving to Idris now." Maryse said before Whispers could say "yes". Whispers dropped something in Alec's hand, a portal shard to keep in contract with her. 

When she was to come back, things would be different. She would be Herondale, one of the youngest and best warriors ever, one Valentine is hunting just like Clary. Alec would be with Magnus and Parabatai with Jace. Alec, Jace, Isabelle, and Clary will go on a mission to bring Valentine to the Clave. 

That is Herondale and her outfit pre-warrior
