Sorkin
Sorkin (unknown-October 2014) was a part of the new Sigma team formed after the original team was killed in Florence by Adriano Maestranzi. He was trusted by Juhani Otso Berg, the leader of the Sigma team and served as an unofficial right-hand man.
In February, 2014 the Sigma team was sent to hunt down the Assassins Harlan Cunningham and Arend Schut who had stolen a precurser box from a facility in Rotterdam. Berg ordered Sorkin to lead the team after Schut while he pursued Cunningham. Underestimating his skill, Sorkin engaged in hand-to-hand combat with Schut. Schut fended him off and used Sorkin as a shield from a sniper shot. Sorkin was injured badly though the team managed to retrieve the box.
In October a team of Assassins led by Gavin Banks destroyed a facility in Paris containing the body of the Sage John Standish. The Sigma team pursued the Assassins but were outnumbered. Sorkin was killed by Galina Voronina reportedly being stabbed seven times by her. The Assassins managed to escape on their ship, the Altair II.
