Even though Zero Day was created as a miniseries, it’s still possible to continue Robert De Niro’s conspiracy thriller for a second season. The ending of Zero Day was fairly definitive: George Mullen (De Niro) reported his findings on the cyberattack, ousted the conspirators in the U.S. government, disbanded the Zero Day commission, and returned to his quiet retirement. Mullen’s decision rocked the entire cast of Zero Day and the country as a whole, but for the most part, the conspiracy thriller’s story was over. There is, however, still a way to continue one of Netflix’s best TV shows for a second season.

Zero Day season 2 is not confirmed by Netflix, but it is possible. In figuring out its winding, complicated conspiracy, Zero Day touched on a number of subjects, from infringements on the constitution of the United States to secretive government weapons programs and political extremism. By examining so many different areas of modern politics in the U.S., Zero Day diversified itself wonderfully, and it opened up several roads and directions to take in the future. So, even though it was intended to end after just one season, Zero Day season 2 could easily happen in the future.

Zero Day Was Created As A Limited Series

The Story Of George Mullen Investigating Zero Day Is Over After Season 1

The main reason Zero Day season 2 hasn’t been confirmed or even hinted at so far is because it was never supposed to happen. Zero Day was written and created to be a limited series, meaning its entire story is done after one season. In essence, Zero Day was the story of George Mullen investigating the cyberattack, not the cyberattack itself, so the show’s creators don’t feel there’s any more story left to tell. George has returned to his private life outside of the public sector, and he’s left the aftermath and cleanup of Zero Day to other public servants.

Zero Day Season 2 Can Continue The Government’s Investigation Into The Unknown Conspirators

Muller Only Uncovered Some Of Zero Day’s Conspirators

While George Mullen’s story may have concluded in Zero Day season 1, the show’s overarching narrative hasn’t. If Zero Day did decide to return for a second season, it could easily use the new episodes to dive deeper into the conspiracy behind the cyberattack and find the rest of the conspirators that Mullen couldn’t oust. Richard Dreyer (Matthew Modine) mentioned that the conspiracy had “partners” who weren’t in the room with the members of the U.S. government. Additionally, Mullen himself noted that “there are most certainly more conspirators from within government and outside it.”

Mullen may have outed the members of the U.S. government that were involved in the Zero Day cyberattacks, but there’s still plenty of other leads to hunt down. It’s easy to imagine Zero Day season 2 following a newly appointed head of a commission to track down the rest of the conspirators across the globe. If it does go global, Zero Day season 2 could even up the action by using military strike teams instead of police, and up the political drama by including geopolitics instead of just internal American interests. Zero Day season 2 could do essentially anything it wants with that setup.

Questions Leftover After Zero Day’s Ending

Zero Day Still Has To Deal With The Fallout Of The Government’s Conspiracy & Find Robert Lyndon

On top of the conspirators that George Mullen didn’t identify, there are several more unanswered questions Zero Day season 2 could address. Perhaps one of the biggest loose threads Zero Day season 2 could tie up is the fate of Robert Lyndon (Clark Gregg), the investor who fled the country. The U.S. government would likely be highly motivated to find him and bring him to justice, yet Mullen seemed unconcerned with him after he left the country. Similarly, Zero Day could check back in on other known conspirators like Alexandra (Lizzy Caplan) as they’re executed for treason.

There’s also the question of Proteus in Zero Day, and whether Mullen was actually being targeted by an experimental weapon or if he was just suffering from the earliest stages of dementia. If his symptoms were due to Proteus, then either the conspiracy went much deeper into the bowels of the U.S. government than previously thought, or some outside group had access to classified NSA weaponry. Either option is harrowing, and would provide more than enough material for a riveting story in Zero Day season 2. That would even provide an opportunity for Robert De Niro to return to the role of George Mullen.

There are so many unanswered questions and new leads for Zero Day to explore that another season is much more than possible, even if it isn’t confirmed.

Another major source of possible storylines could be Monica Kidder (Gabby Hoffman). Zero Day briefly mentioned Kidder’s antitrust suits as a side story, but Zero Day season 2 could dive deeper into the implications of tech billionaires holding America’s digital infrastructure hostage. The show could even get more technical and focus on America’s attempts to stop another Zero Day from happening, whether that’s through government oversight or more aggressive antitrust legislation. There are so many unanswered questions and new leads for Zero Day to explore that another season is much more than possible, even if it isn’t confirmed.
