Freddy

Freddy is a doctor part of the medical team in the Philadelphia complex of Abstergo Industries. Freddy was secretly a mole in the Templar Order working alongside Violet da Costa for the Instruments of the First Will and their mistress Juno.

In 2016, Freddy was tasked to assist André Bolden, as the old man had difficulties coping with his sessions in the Animus. Worried by the prospect of the Koh-i-Noor falling into the hands of the Templars, Freddy tried to stop them. First by ordering the Assassination of the director of the Philadelphia complex, Juhani Otso Berg, which failed and then by murdering Caitlin Gift, the technician of the project.
