'The Old Guard' Plot Holes: The Biggest Questions the Movie Left Unanswered

The Old Guard on Netflix does a good job of taking viewers through the thousands of years of history that the group of immortal mercenaries has been through. However, writer Greg Rucka's decision not to explain too much of the mythology leaves a number of holes in the plot that viewers have to work out for themselves.

In an interview with SciFiNow, for example, Rucka said: "I wanted to make it really clear that the first story is not concerned with the 'how' or the 'why' of their immortality." Though this decision stops the film from being weighed down by exposition, it does leave a lot of major questions unanswered that could be explained in a potential sequel–or might never be explained.

WARNING: The following contains spoilers for the entirety of The Old Guard on Netflix.

How did the team find Nile?

The main action of The Old Guard kicks off when the team has visions in which they see Nile (played by Kiki Layne) dying and coming back to life, cut to Andy (Charlize Theron) tracking her down in a warzone. What the film does not explain, however, is how exactly they found her.

It is implied that something in these visions helps them track her down. But if that were true, why hasn't Andy been able to use her visions to track down Quynh (Van Veronica Ngo) over the centuries—after all, we know that Nile has been having visions of Quynh's watery torture.

How did Andy escape the Iron Maiden?

Speaking of that torture, the details of what happened just after Quynh was put in an Iron Maiden and throw into the sea are left deliberately vague. In the flashback, both Andy and Quynh are implied to be set for the same fate. However, the fact that Andy is around during the events of The Old Guard suggests that either she escaped her iron coffin or, more likely, she managed to escape before she was thrown into the water.

However, we never get to see how Andy escaped. But with Quynh now free and seemingly about to be the villain in a potential sequel to the Netflix movie, we may learn what happened if there is an Old Guard 2.

Why did Andy's immortality stop?

In the world of The Old Guard, immortality is a temporarily (but long-lasting) thing that all of the band of fighters are destined to lose at one point. Midway through the movie, Andy realizes she is not healing from her injuries, meaning that she is now mortal again.

The movie, however, deliberately does not explain why and how she has lost her immortality—though Rucka teased that viewers may find out at some point. He told Polygon: "That was something that I had no interest in exploring in the comic, but I think when you're making a movie you're a little more obligated to at least promise answers to questions."

The movie hints that Andy lost her immortality when she grew tired of living, but there could be more to it that could be explored in a sequel.

How does Andy know which people to save?

In a late reveal, Copley (Chiwetel Ejiofor) revealed that the Old Guard has throughout time saved hundreds of people who would go on to save humanity. For example, he mentions that one person they saved would go on to prevent a nuclear catastrophe. The question is how do they know what these people's role in history will be.

There seem to be two possible answers—either the team can see into the future, or there is some higher power controlling their actions. Both of these could add a fascinating new dimension to any sequel.

How does Quynh know Booker?

In the final scene of the movie, the exiled Booker (Matthias Schoenaerts) comes home to find Quynh, drinking a glass of water. She tells him, "Booker, it's nice to finally meet you." With Quynh believed to be buried underwater for centuries, the movie wants us to ask exactly how she knows him. Quynh may have had visions of him similar to the visions the other immortals have had, or alternatively she may have been following the team for some time. The Old Guard 2 is sure to tell us if it gets made, but in the meantime, Rucka teased to Polygon: "We wanted to say 'Look, the mythology is bigger than you think it is. There is more going on."

The Old Guard is streaming now on Netflix.
