Episode 6 puts the team in a crisis they have never faced before. A U.S. Navy scientist may be patient zero for Ebola, and the team must move fast to find out how the infection started. Mackey and JD follow clues that lead them to a lab connected to secret military research, hinting at a bigger and more dangerous plot. DeShawn and Evie also make a troubling discovery that may link directly to the outbreak.

A brief recap of episode 5 before NCIS: Sydney season 3 episode 6 arrives

Episode 5, “Black Is White,” began with the shocking death of U.S. Navy attaché Felix Ebrahimi, who was found with a pawn-shaped USB in his throat. The case led the team to an international chess tournament, a dangerous foreign regime, and a spy network pretending to be refugees.

Blue stepped in to help decode the files and uncovered the truth that Ali Azad and his daughter Rana were in serious danger.

The team learned Felix was killed for trying to protect information about a murdered woman and a major leak involving foreign spies. Hassan Saberi, who pretended to be a dissident but still served his government, carried out the attacks and kidnappings.

NCIS saved Ali in a tense rescue and secured Rana’s safety through a risky trade. In the end, Blue rejoined the team after JD quietly helped her, and Mackey kept the Ghost file as protection, setting up even bigger stakes for episode 6.
