Doors International showcases a new directed EMP weapon. Lili receives news that her estranged father Colonel Edward Purcell has died. Unbeknownst to her, his mind has actually been transferred to the body of a young convict named Thomas Blanchard, who then steals the new weapon. He goes to Augur to try to fence it. Doors plans to buy it, although he suspects it could be a trap. Da'an orders Lili removed from the investigation to grieve despite her protests. She continues investigating in secret and finds the thieves, but ends up captured by them. Augur and Boone smell a rat and recommend that Doors call off the buy. Blanchard/Purcell uses the weapon to knock out one of Doors International facilities, costing Doors millions and forcing him to agree to the buy. Blanchard/Purcell is questioning Lili about her past and family. Da'an and Zo'or reveal to Boone and Sandoval that all this has been orchestrated in order to lure Doors out of hiding. Blanchard/Purcell and his accomplice are taken to the Resistance headquarters. Boone warns Doors, but Blanchard/Purcell uses the weapon to disable the headquarters and take Doors hostage. Lili appears, which distracts Blanchard/Purcell long enough for Doors to pull out a gun and shoot him. He dies in Lili's arms.
