With season 4 of Black Mirror, the BBC-turned-Netflix show is looking to explore outside of its usual anthology format. So far, each episode of Black Mirror, like the Twilight Zone, has been a self-contained story. While the Twilight Zone often explored the supernatural, however, Black Mirror mainly delves into near-future science fiction, exploring how technology could affect our lives (and deaths) in the rest of the 21st century. The title of the show is an opaque reference to the ever-present reflective surfaces of computer, television, and phone screens. Show creator Charlie Brooker recently hinted at the idea that season 4 might include sequels to episodes from the previous three seasons. Brooker noted that he would ultimately move ahead with the episode ideas that he felt were the strongest, so sequels are a possibility, but may not appear in season 4.Viewers of Black Mirror may find the idea of sequel episodes surprising, because each episode of Black Mirror has a certain level of finality to it. Even if the protagonists aren't dead, the show often chooses a particularly poignant (and usually harrowing) moment to close on. One of the greatest strengths of Black Mirror is its surprising twists and often devastating endings. A sequel could potentially lessen the impact of the original episode if it wasn't handled with extreme care. For example, neither the Emmy-nominated "San Junipero" or the shocking "Shut Up and Dance" would benefit from a sequel.On the other hand, sequel episodes are also a new an opportunity. Some fans of the show have already developed elaborate theories to show that all of the seemingly different worlds of Black Mirror are actually part of the same timeline (although some particular episodes appear to be relatively far in the future). There are a number of Easter eggs hidden within episodes that reference events in other episodes, and so Brooker may have engineered the show to connect from the beginning. Perhaps the most innovative and exciting sequel would be an episode that bridges together two seemingly separate stories from two previous episodes.With only thirteen episodes over three seasons (and a Christmas Special), there aren't too many options to choose from for sequels. However, since some of the episodes lend themselves better to a continued story than others, here are our top picks for Black Mirror episodes that deserve a sequel:

The Entire History of You

Of the three episodes in the original season of Black Mirror, "The Entire History of You" is one that offers the best opportunity for a sequel. At the end of the episode, Toby Kebbell's Liam violently cuts out the "grain" implant that allows him to replay memories. Liam's fate is left unknown at the end of the episode, but a sequel could explore what his life is like "grain free" in a world where everyone around him is constantly playing and replaying memories. Alternatively, another episode could serve as a "sequel" if it followed the character of Hallam (Phoebe Fox) who attends the same dinner party as Liam and his wife Ffion (Jodie Whittaker a.k.a. the new Doctor) - at the dinner party, Hallam reveals that she already lives "grain free" after her "grain" was violently severed during an attack. At the party, Hallam says that she prefers living "grain free", and her story could be another entry point (whether continuing Liam's story or telling a new story altogether).

White Bear

White Bear Black Mirror episode

"White Bear" is the apparent frontrunner for a sequel, and with good reason. The episode creates a vivid intersection of entertainment, violence, and justice, and the material has a lot of potential for additional episodes. In "White Bear," Victoria Skillane (Lenora Crichlow) seems to be trying to survive in an apocalyptic landscape, but in a shocking twist it's revealed that she is actually a criminal whose punishment is being tortured in a sick revenge-themed amusement park. Victoria was complicit in the murder of a child (she videotaped her boyfriend torturing and killing a young girl). Now, her memory is wiped every day and she runs for her life from a multitude of terrors while spectators film her on their phones.

One potential sequel could explore Victoria escaping or breaking out of the cycle that "White Bear" sets up. However, it might be more interesting to explore "White Bear" from a new perspective - perhaps from one of the onlookers who attends the "White Bear Justice Park".

Men Against Fire

"Men Against Fire" told a small narrative while introducing a large new world: the US military has started using augmented reality (called MASS) in order to get soldiers to commit a genocide in Europe (specifically, but perhaps not exclusively in Denmark) as part of a worldwide eugenics military campaign. Soldiers like Stripe (Malachi Kirby) see the targets of this genocide as monsters whose appearance and voices are altered.

While Stripe's story seems finished as he retires to a shack that appears to him as a pristine home, the global war would be a fascinating setting for a myriad of other stories. Since each Black Mirror episode seems to center on a new piece of technology, the military seems like it could offer up some terrifying gadgets. Sequels could focus on soldiers (including Madeline Brewer's Hunter or Michael Kelly's Arquette from "Men Against Fire"), war correspondents, or even survivors of the genocide.

Hated in the Nation

Given the police procedural format of "Hated in the Nation", it might seem the most obvious choice for a sequel. Its familiarity allows it to translate easily to a sequel; the detective team from the episode simply need to be given a new case, preferably interacting with a new strange technology, and they can deliver a completely new story while providing some continuity.

"Hated in the Nation" contains a reference to "White Bear" in it - one of the protagonists of "Hated in the Nation" Blue Coulson confides that she left forensics after she cracked the case in "White Bear". A new episode in season 4 could either act as a prelude to "White Bear" and "Hated in the Nation" or it could act as a sequel that further brought the episodes together - perhaps if Victoria escaped from her unending punishment, the detectives from "Hated in the Nation" could be tasked to find her.

White Christmas

Jon Hamm in Black Mirror

The "White Christmas" episode of Black Mirror is an extended 74 minutes, and contains multiple opportunities for sequels. Both of the major characters end the episode in terrible situations (which have certain parallels/connections with "The Entire History of You" and "White Christmas" respectively). Jon Hamm's Matt finds that he is "blocked" by everyone with a "Z-Eye", which appears to function similarly to the "grain" in "The Entire History of You"; whereas Joe, who is revealed to be a "cookie" computer program is forced to listen to "I Wish It Could Be Christmas Everyday" on repeat, much like Victoria of "White Bear" is forced to relive the same experience each day as a punishment.

Perhaps Matt could discover people without "Z-Eyes" or "grains" (maybe even Liam himself!) in a sequel-crossover. Since Matt is blocked, he would be starved for human contact. Additionally, since the police tell Matt that all Sex Offenders are blocked by everyone, perhaps Kenny from "Shut Up and Dance" could also make an appearance.

If the sequel instead followed Joe, it could explore what happened to him (and not his cookie). Does Joe face a similar fate to Victoria? He is charged with the death of a young girl, and so he may face a cruel and unusual sentence. Or, if Black Mirror wanted to have a creative twist, an episode could explore the lives and work of architects of these creative and terrifying punishments. After all, someone must come up with these technological tortures - other than Charlie Brooker, of course.
