It was 1998. The X-Files was at the absolute peak of its cultural powers, coming off a massive feature film and a move from the rainy gloom of Vancouver to the sun-baked streets of Los Angeles. Fans were worried. Would the show lose its edge? Then came Season 6, Episode 6. Titled How the Ghosts Stole Christmas, it wasn't just a monster-of-the-week entry. It was a weird, claustrophobic, psychological two-hander that basically stripped Mulder and Scully down to their neurotic cores.
Chris Carter wrote and directed this one. You can tell. It feels intimate. Honestly, it’s basically a stage play with more blood and better lighting. On Christmas Eve, Mulder drags a reluctant Scully to a legendary haunted house in Maryland. He’s obsessed. She’s annoyed. She has gifts to wrap and a family that probably wonders where she is half the time anyway. But Mulder has a story about a lovers' pact from 1917, and he isn't letting it go.
What follows isn't just a ghost story. It’s a dissection of why these two people are the way they are.
The Setup: A Gothic Nightmare in a 1910s Mansion
The episode takes place almost entirely within the confines of a decaying, cavernous mansion. It’s classic Gothic horror. We’re talking creaky floorboards, secret crawlspaces, and shadows that seem to swallow the characters whole. Mulder’s pitch to Scully is simple: a couple, Lyda and Maurice, made a suicide pact in this house so they could spend eternity together. Now, they spend their afterlives haunting anyone who breaks in on Christmas Eve.
Scully doesn't buy it. Obviously. She’s the scientist. Even after six years of seeing aliens, shapeshifters, and liver-eating mutants, she’s looking for the gas leak.
"Mulder, under the circumstances, I'd say that 'mistletoe' is the very last thing on my mind," she tells him. It’s one of those quintessential Scully lines. She’s cold, she’s tired, and she just wants to go home. But the house has other plans. The doors lock. The windows are bricked up. The physics of the building start to warp.

Ed Asner and Lily Tomlin: The Ghosts We Deserved
The real magic of How the Ghosts Stole Christmas comes from the guest stars. Getting Ed Asner and Lily Tomlin was a massive coup. They play Maurice and Lyda, the ghostly inhabitants of the mansion, and they don't play them as scary spirits. They play them as a bickering, bored, highly intellectual couple who have been dead for eighty years and are looking for some fresh entertainment.
They aren't there to jump-scare you. They’re there to psychoanalyze you.
Maurice takes on Mulder. Lyda takes on Scully. It’s brilliant. Maurice mocks Mulder’s "unrelenting narcissism" and his desperate need to be special. He calls Mulder a "lonely man" who fills the void in his life with ghosts and aliens because the alternative—being alone with himself—is too terrifying. It’s harsh. It’s also kinda true.
Meanwhile, Lyda goes after Scully. She plays on Scully’s skepticism, suggesting that her devotion to Mulder isn't about the truth or science, but about a pathological need to be the "voice of reason" for a madman. It’s a brutal look at their partnership. The ghosts argue that Mulder and Scully are codependent, miserable, and destined to end up just like them—trapped in a dark room together forever.
Why the Psychological Horror Works Better Than the Gore
There is some blood. Actually, there’s a lot of it toward the end when the ghosts trick Mulder and Scully into shooting each other—or at least, making them think they’ve shot each other. We see them crawling across the floor, bleeding out, reaching for one another in a gruesome parody of the original suicide pact.

But the real horror is the dialogue.
The episode suggests that Mulder and Scully are "dark lovers" who are too afraid to admit their feelings, so they chase monsters instead. It’s a meta-commentary on the "will they/won't they" tension that fueled the show for a decade. By 1998, the audience was screaming for them to get together. This episode looked the fans in the eye and said, "Is this really what you want? For them to be trapped in each other's neuroses until they die?"
The pacing is frantic but contained. One minute they're arguing about infrared heat signatures, the next they're staring at their own "corpses" under the floorboards. It’s disorienting. It’s supposed to be.
The Visuals: Vince Gilligan’s Influence and the Look of Season 6
While Carter directed, the fingerprints of the "LA era" are all over this. The cinematography is lush. Even though it’s a "dark" episode, the blacks are deep and the warm oranges of the fireplace create a sense of cozy dread.
The production design by Corey Kaplan is top-tier. That house feels like a character. It’s crowded with junk, old books, and memories. It feels heavy. When Mulder and Scully are separated, the house seems to stretch, making the hallways look miles long. It’s a trick used in classic horror films like The Haunting, and it works perfectly here to emphasize the isolation the ghosts are trying to instill in our heroes.

The Ending: A Rare Moment of Mulder and Scully Peace
After surviving the psychological onslaught and realizing the ghosts were just playing mind games, Mulder and Scully escape. They run out into the night, back to their separate lives.
Except they don't.
The final scene is one of the most beloved in the entire series. Scully shows up at Mulder's apartment. She can't sleep. He can't sleep. They sit on his couch and exchange gifts. It’s a quiet, domestic moment that counteracts all the cynicism of the ghosts. Lyda and Maurice might have been right about their flaws, but they were wrong about the outcome. Mulder and Scully choose to be together not because they're "trapped," but because they actually care about each other.
They open their gifts. It’s a small, human victory in a world filled with conspiracies and spirits.
Actionable Takeaways for Your Next Rewatch
If you’re planning on revisiting How the Ghosts Stole Christmas this December, here’s how to get the most out of it:
- Watch for the mirrors: The episode uses reflections constantly to show the "doubling" of the characters. Notice how often Mulder or Scully are framed next to a mirror or a window that shows back a distorted version of themselves.
- Listen to the score: Mark Snow’s music for this episode is heavily influenced by classical themes and Christmas carols, but twisted into minor keys. It’s some of his best work.
- Pay attention to the psychology: Don't just look at it as a ghost story. Listen to the specific insults Maurice and Lyda hurl. They are basically reading the characters' psychiatric profiles out loud.
- Check the lighting transitions: Notice how the lighting shifts from harsh, cold blues when they are "scientific" to warm, suffocating reds when the ghosts are winning.
This episode remains a masterclass in how to do a "bottle episode" right. It costs less to produce because of the single location, but it delivers more character development than ten episodes of the alien conspiracy arc ever could. It’s funny, it’s spooky, and it’s deeply, weirdly heart-warming.
To truly appreciate the depth of this episode, compare it to the "shippers" episodes of later seasons. You'll see that while the show eventually leaned hard into their romance, this Season 6 gem was the first time the writers really admitted how much these two broken people needed each other to survive the dark. It isn't just a Christmas story; it's the definitive statement on the Mulder and Scully dynamic.
