David has the ability of Telepathic Relay. He has a minor form of telepathy to act as a "relay station" for a group of minds, allowing said minds to "speak" to one another through him in real time.
David is naturally suspicious of everything and everone. He is rather stoic preferring working behind the scenes, which most perceive as cold. He cares deeply for the students and staff, but knows that his job is to protect them not to be their friend.
There is very little David Mizrahi can't do. Expert marksman, covert ops agent, security detail professional, he has spent most of his life risking his life for his country. David was born and raised in Israel. The son of two former Mossad agents and the elder sibling to his baby sister, he was excited to serve his country with pride. His parents were reluctant to allow their sweet, naive little boy into the harsh word of covert affairs. Unfortunately their fears where realized when David came home from his first mission. There was a hardness that formed in little David. Even his body language became more closed off and his parents were quick to notice.
He served as a Mossad agent until a car bomb went off near his parents' home, destroying the apartment building and killing David's parents and little sister. David, who was visiting was buried in the rubble and presumed dead. He was slowly being crushed to death for eight days, but on the morning on the ninth day the rubble above him simply disappeared. Dehydrated and wounded, David believed he was hallucinating and promptly passed out.
When he awoke he was found himself in a private hospital with Anneliese Devereaux sitting reading a book at his bedside. She told him he was allowed to stay as long as he liked, but informed him that his government had declared David Mizrahi dead. The Headmistress offered him an opportunity to become her head of security and promised that if he ever chose to leave she would provide him with the means to start a fresh life.
David has been at Anneliese's side ever since.
