Let's put it bluntly: The Old Guard is a lot of fun. For two hours, viewers get to watch an immortal Charlize Theron (playing Andy, who has been kicking ass for literally hundreds of years) lead a team of fellow immortals as they run from an evil pharmaceutical company (led by a villain played by Harry Melling, Harry Potter's Dudley Dursley). Just like with Mad Max: Fury Road, Atomic Blonde, and Hancock before it, Theron proves she can absolutely own an action movie. And also like those movies, The Old Guard has an ending that might get you thinking: "What Next?"

The Old Guard is based on a series of graphic novels written by Greg Rucka (who also wrote the movie's screenplay), so there's the idea that this could seemingly be an ongoing story. And that's what the end of the movie seems to suggest, should the movie be as big a hit as Netflix hopes it is. So at the end of the day, here's our major takeaway from what happened at the end of The Old Guard, and how it could affect the future of this potential new aciton franchise.

Who was that at the end?

In one of the final scenes of the movie, a no-longer-immortal Andy (Theron) tells Booker (Matthias Schoenaerts) that as punishment for his (well-intended) betrayal, he'd have to separate from the rest of the team for 100 years, before reuniting in the same spot.

The film properly endsa title card that says The Old Guard appearsbut a post-credits scene of sorts picks up immediately after. Time jumps forward six months, and we find Booker, heavily drinking in a building in Paris. He drops his bottle, and as it shatters he hears movement in the next room. Booker enters with his gun drawn, and finds a woman in a red robe, sipping on a glass of water. "Booker," she says. "It's nice to finally meet you." And the credits begin to actually roll.

This woman is Quynh ( Veronica Van Ngo )one of the original two immortals. Earlier in the film, it was clarified that she was the second oldest of all of them, and that she was a friend and inseparable with Andy. She entered the story because Nile (Kiki Layne) kept having dreams of a woman drowning over and over againand given that the immortals share dreams, they all knew exactly who she was seeing.

Quynh and Andy got captured around the time of the witch trials, and while Andy managed to escape, Quynh ended up getting thrown to the bottom of an unknown body of water, weighted down in a metal suit. Since she never truly dies, it's here that she drowned over, and over, and over again. Nile kept seeing her death, just as the movie showed her horrified screams from within the suit.

So when Booker sees her at the end, viewers who remember about an hour earlier in the film should know exactly who that is. And since the immortals all share the same dreams, that means she's seen his dreams as wellhence the "nice to finally meet you."

It's an obvious set-up for a sequelis Quynh mad? Is she happy? How did she escape? How long has she been escaped? It can't have been that long, we can say definitivelyat the longest it was the six months we've seen on screen, because we can fairly safely assume that when Nile dreamed of her drowning, it was still happening in real time.

In a possible future Old Guard 2, there's a lot of potential for what could be done with Quynh's character. While Copley (Chiwetel Ejiofor) seems to have turned to be fully on the side of the good guys by the end of the movie, that doesn't mean that someone else similar to Merrick could have a similar evil plan to exploit the members of the team. That person could have figured out where she is, freed her, and is now using her to gather the rest of the team back up.

There's also the possibility that she figured out a way to free herselfwho knows what someone with that sort of ability would be capable of with literal hundreds of free time.

What about the rest of the ending?

In the moments after they part ways with Booker and before we see the six-months-later scene, Andy, Nile, Joe, and Nicky meet up with Copley once again and see all of his research and findings taped to the wall.

As discussed earlier in the movieand as exemplified when Andy received medical aid from a strangersaving people creates a butterfly effect in a pay-it-forward way. Copley says that he's only gone back about 150 years (one note shows Andy saving someone in 1918), but there's a chain of people who are saved then saving others. When that person saved someone, and that person saves people, and the effect leaves an untraceable trail of good deeds and lives saved. "When you think about how old you are, the good you've done for humanity becomes exponential."

When they realize all the good that's been done, Nile makes a comment aloud to the room: "Maybe this is why, Andy," a reference to Andy's earlier suggestion that she just doesn't understand why she (and those around her) have been granted the ability to live forever. Now she can see her place in the world, and the difference that she's somewhat unknowingly had.

Impressed with the research Copley has done (and knowing his former status in the CIA, and seeing how he successfully managed to track and hang with the team for the entire film up to this point), Andy essentially tells him that he's now going to be their handler. He's going to keep them undetected and find things they can do to help. He's going to get back in their good graces after teaming with Merrick for the whole movie (he might get forgiven a little bit easily, but oh well). And he tells them that he'd be honored. And now we're ready for The Old Guard 2.
