took viewers on an engaging mystery filled with twists, turns, and dark, tragic secrets. The show focused on Elisa (Denise Gough), a mother whose daughter Lucia (Beatrice Campbell) was stolen by another woman, Rebecca (Holliday Grainger). It was quickly revealed that Rebecca (aka Nina) wasn't who she claimed to be—and neither, it turned out, was Elisa.

While the central mysteries of The Stolen Girl were all solved, a few moments still left us scratching our heads. From a bizarre kidnapping plot to some questionable journalistic decisions, we've rounded up 10 important details that didn't make sense about the show.

On the surface, Nina's plot to kidnap Lucia was well-orchestrated, requiring large sums of money and years to pull off. But in truth, so much of the plan relied on sheer luck. For example, if Elisa's plane hadn't landed late, leaving her frazzled, and if her son hadn't continuously honked the horn, it seems likely she would have turned down Nina's offer to watch Lucia. Additionally, if Fred (Jim Sturgess) hadn't fallen asleep, he likely would have learned Lucia was missing much earlier, meaning the police could have rescued her before she ever left the town.

Admittedly, Nina's daughter Josie (Robyn Betteridge) played a not-insignificant role in helping her mother convince Elisa to let Lucia come over. Additionally, Elisa's plane had been late before, and it's possible Nina knew of this pattern. However, that still doesn't explain why Nina would leave so much up to chance. On most other days, her plan would have failed, potentially causing Elisa to become suspicious. Honestly, this feels more like a crime of opportunity than something carefully coordinated and carried out.

In order to kidnap Lucia, Nina hires a man named Matkovic, who drives the girl to France. En route, they stop at a gas station, and Lucia tries to run away. This attempted escape is what ultimately enables the police to locate her. However, if Lucia had simply stayed with Nina, she probably wouldn't have tried to run, which leads to an important question: why was Matkovic involved in the plan at all?

Ultimately, Matkovic just spelled trouble for Nina. He was a liability because he knew her location and what she had done. Plus, after the police discovered his identity, he came to her house seeking money; while this altercation ultimately ended in his death, it could easily have ended in Nina's. It's possible that Matkovic played some important role in getting Lucia to France, such as by smuggling her aboard a ferry, but even if this were the case, we wonder why Nina (who also traveled to France) couldn't simply have done it herself.

After kidnapping Lucia, Nina's actions become a bit contradictory. She seems worried after a neighbor stops by, implying that she wants to sequester the girls away from others. Yet, she also tells them that they're going to be able to go out and make friends, even taking them down to the beach as if trying to convince herself this is true. While there, she sees Lucia's photo in a newspaper and seems surprised—which is a surprising reaction for audiences, because what exactly did she think was going to happen?

Of course, kidnapping a girl and pretending she's yours already implies something might be up mental health-wise. It's possible that Nina was so caught up in her fantasy that she was having trouble seeing reality for what it was. Still, given her aforementioned "meticulous" kidnapping plot, it seems fair to think she'd have some sort of long-term plan in place—or, at the very least, that she would have realized they'd have to stay hidden indefinitely.

Selma (Ambika Mod) was a journalist who believed that Elisa was involved in Lucia's disappearance. Early on, she told her boss that she thought Elisa was faking her identity because she was constantly on social media, yet had no presence several years back. To be fair, Selma was proven right: Elisa had been part of a cult and only started social media after leaving. However, it was a heck of a jump to think that no social media presence meant that Elisa was pretending to be someone else.

It's possible that Elisa's lack of social media presence was simply because she didn't use social media up until that point. The timeline corresponded with early motherhood, so she might have chosen to go online then since she had more to share. Additionally, there were various other, more logical leads that Selma could have pursued, such as assuming that the kidnapper was connected to one of Fred's clients.

After publishing her article about Elisa, Selma seemed genuinely worried that the coverage could put Lucia at risk. She also seemed taken aback that so much negativity had befallen Elisa since the article. Like several of the other entries on this list, we have to wonder why she didn't realize this might happen. It seems obvious that a hit piece would result in negative attention for Elisa and potentially endanger her daughter simultaneously.

Obviously, it's possible that Selma is simply newer to writing about stories like this, so she didn't realize that an article related to a kidnapping case could have implications that a story about an aggressive pig wouldn't. It's also possible that Selma simply wanted the scoop and didn't consider the potential ramifications. In either case, this suggests she has a lot to learn as a journalist if she hopes to continue working in the field.

After discovering that Elisa was in a cult, Selma journeys to her hometown to hear more about how the cult functions and who Elisa was. However, the audience doesn't learn much about the cult except that they wear red, trade goods instead of using money, and claim to avoid modern things. Yet, several modern items are worn or used by the members, and outside of the terrible things Elisa's father did to her (and what her mother allowed), the cult itself seems fairly innocuous. Given the cult's importance to the story, it's strange we didn't learn more about it.

To be fair, this isn't an error of the show so much as something we'd like to know more about. It seemed like an obvious story for a journalist like Selma to follow, but once she was done learning about Elisa, her interest in the cult apparently vanished—but as viewers, ours only grew.

Toward the end of the show, Lucia discovers that Nina has been altering photos to resemble her, and she decides to run. However, we don't understand why she believed Nina's lie so easily from the beginning. Yes, she's a child and easily influenced, but she lived her entire life with her parents. It's strange that she didn't at least have more questions (or even seem to miss them).

Obviously, we don't blame Lucia for getting kidnapped, nor was she at fault for staying with Nina and Josie. She's a little girl, after all, as well as the victim in everything that transpired. However, we do wonder why she didn't put up more of a fight to escape, especially given the fact that Nina was constantly away, which gave her the perfect chance to flee.

Sure, it's possible that the birthmark photos might have convinced her that Nina was telling the truth, or maybe she developed a form of Stockholm Syndrome, but she'd had several chances to run early on and didn't really seem interested. It's also possible she didn't run because she was uncertain where she was, but that didn't stop her from running at the gas station, so why the hesitation now?

Marcus (Xavier Samuel) and Elisa were having an affair shortly before she became pregnant with George. He was there when she accidentally pushed her father down the stairs and also in the car when she collided with Nina's husband and daughter. It's obvious that he loved her, since he decided to take the fall and go to prison instead. However, we're surprised that the police didn't find and look into this connection—and even more surprised that Elisa didn't mention it.

Yes, Marcus was in jail, but he'd still likely be a person of interest in Lucia's case. Additionally, Elisa might have gotten into trouble for exposing her connection (as later happens), but she must have realized said connection could be pertinent to the case, so it should have been prioritized. In fact, if the intel about Marcus had been discovered/revealed sooner, the police could have easily connected him to Nina, and in turn rescued Lucia more quickly. Since it happened years ago, Elisa might not have thought it was relevant, but given the severity of what happened, she probably should have considered it.

After Nina's husband and daughter were killed, she went to Elisa's cult seeking answers. However, it's strange that she'd do this, given that Marcus took the fall. Nina was turned around when the crash occurred, so she didn't see a woman in the car (and later, it was made obvious that she'd had no idea that Elisa was driving). So, why did she go to the cult trying to learn more about her husband and daughter's deaths when she had no reason to think it wasn't an accident and that Marcus hadn't been driving alone?

Maybe the police found evidence that someone else had been with Marcus, but if so, the viewer wasn't told this. Additionally, maybe the cult members were the only people nearby when the crash occurred, so Nina had hoped to ask them some questions. Still, it seems pretty convenient that Nina found Elisa's mother, of all people, to speak to, and even stranger that Nina would jump to kidnapping instead of getting the police involved after learning of Elisa's involvement.

Perhaps the biggest thing that doesn't make sense about The Stolen Child revolves around Elisa's connection to Nina. Elisa ran over Nina's husband and daughter, and yet, she apparently never saw photos of Nina. Maybe she wanted to put the whole thing behind her and never bothered to look up the case. However, that makes us question who Elisa was as a character, since she basically abandoned Marcus in jail, ignored her victim's widow, and more generally shirked all responsibility before trying to return to her normal life.

Honestly, this seems like a plot hole that turns the entire series on its head. Elisa should have recognized Nina, or at the very least, Nina should have worried that Elisa might. After all, images of her outside the trial were publicly available and in the news. Just like with the rest of the kidnapping plot, Nina really lucked out that Elisa didn't know who she was from the beginning, or else the kidnapping (and show as a whole) would have ended right there and then.
