The legendary X-Files series dealt with the cases of two FBI agents, but there was a subplot with the search for Fox Mulder’s sister.
Chris Carter’s science fiction television series, Expediente X (The X-Files)is played by David Duchovny as the FBI special agent Fox Mulder and his fellow agent Dana Katherine Scully (Gillian Anderson). While the series has various plots and storylines, what happened to Fox Mulder’s sister named Samantha Mulder is one of the main focus of the show. Despite this fact, the explanation behind her disappearance becomes increasingly complex and somewhat confusing with each additional plot. Here is the explanation of what exactly happened to Samantha Mulder.
At the beginning of the series, Fox Mulder is introduced as a conspiracy theorist who has been given the nickname “Spooky Mulder” for his seemingly mindless infatuation with the paranormal. As season 1 progresses, it is revealed that the purpose behind him devoting his life to the unsolved ‘X-Files’ cases is to track down his younger sister, Samantha. Agent Mulder clearly remembers how his sister was abducted by aliens when they were both children. So he becomes obsessed with finding her or at least getting an answer to her disappearance. Because the truth is out there.
As the series progresses, he continues to fail in his attempts. But ultimately his fate is revealed in season 7 episode 11 titled “Closing”.
In The X-Files, there are numerous twists and turns that lead to the discovery that Fox Mulder’s sister has actually passed away years before he joined the FBI. It wasn’t the most satisfying ending. But he gave the protagonist the closure he needed to get on with the cases, without having any senseless hope that his sister was still alive. With clones, medical tests, and kidnappings, Samantha Mulder’s story became a confusing mess. But with close attention to the details of a specific episode, what really happened to it can be explained.
Fox Mulder was right, as Samantha was abducted by aliens, because her father made a deal with them to allow them to take her. In 1973, the Syndicate was formed and requested a son from the Mulder family. Initially, his father chose Fox, but the Cigarette Smoker forced the aliens to take Samantha. When Mulder discovers his diary with the help of a medium, he details the experimentation he had to undergo until it was no longer deemed valuable. At that time, she Samantha was sent to live at April Air Force Base in California, where the Cigarette Smoker continued to perform various tests on her.
She suffered a lot until she found peace.
At the age of 14, Samantha escaped from the facility. After a brief hospital stay where she did not reveal any information about herself, Samantha disappeared and was never heard from again. Since she was consumed in a spiritual intervention by beings called “Walk-ins”. Its purpose is to rescue children who are condemned to live with constant pain and suffering. When her captors discovered Samantha’s location, her Walk-ins rescued her by turning her into starlight energy and giving her a painless death. In the X-Files season 7, episode 11 titled “Closure”, Mulder finally accepts that his sister is gone and that they are both free.
Throughout the X-Files series, various beings pose as Samantha to fool Special Agent Mulder. It’s not until “Closing” that her true fate is revealed, discrediting any other theory about what happened to Samantha.
Conclusion: She was abducted by aliens, but passed away since the Walk-ins turned her into starlight. Mulder’s long search to find his sister in the first seven seasons of The X-Files was not in vain. Because in the end, she found peace with the help of the Walk-ins.
