Spoiler alert! Sometimes TV shows shock their audiences with mind-blowing twists and surprises, but the writers are often clever enough to foreshadow these events with very subtle references. Here are 10 of them.
**Many spoilers ahead.**
1. The Walking Dead
During season five of The Walking Dead, Glenn (Steven Yeun) picks up a baseball bat a few times in the Alexandria Safe-Zone. He was also almost killed by one at Terminus at the beginning of the season. Two seasons later, Negan (Jeffrey Dean Morgan) brutally kills Glenn with his barbed-wire baseball bat (a.k.a. Lucille) during the season seven premiere.
2. Breaking Bad
In Breaking Bad's second season finale, a Boeing 737 crashes over Albuquerque, New Mexico. While the event was hinted at throughout the season during the black-and-white teasers at the beginning of each episode, the titles of certain episodes predicted the crash altogether. The titles “Seven Thirty-Seven,” “Down,” “Over,” and “ABQ” spell out the phrase “737 Down Over ABQ,” which is the airport code for the Albuquerque International Sunport.
3. Game Of Thrones
In “The Mountain and the Viper,” a season 4 episode of Game of Thrones, Petyr "Littlefinger" Baelish (Aidan Gillen) tells his stepson, Robin Arryn (Lino Facioli), “People die at their dinner tables. They die in their beds. They die squatting over their chamber pots. Everybody dies sooner or later. And don’t worry about your death. Worry about your life. Take charge of your life for as long as it lasts.”
Throughout that same season, viewers see King Joffrey Baratheon (Jack Gleeson) die at a dinner table during his wedding and watch Tyrion Lannister (Peter Dinklage) strangle his former lover, Shae (Sibel Kekilli), in bed, before killing his father, Tywin (Charles Dance), while he’s sitting on a toilet.
4. Arrested Development
Throughout seasons 1 and 2 of Arrested Development, there are a number of references that foretell Buster Bluth (Tony Hale) losing his hand. In “Out on a Limb,” Buster is sitting on a bus stop bench with an ad for Army Officers, but the way he’s sitting hides most of the ad, so it reads “Arm Off” instead. Earlier in season 2, Buster says “Wow, I never thought I’d miss a hand so much,” when he sees his long lost hand-shaped chair in his housekeeper’s home.
5. Buffy The Vampire Slayer
In season 4 of Buffy the Vampire Slayer, Willow (Alyson Hannigan) comes out as gay and begins a relationship with Tara (Amber Benson). However, in the episode “Doppelgangland” in season 3, a vampire version of Willow appears after a spell is accidentally cast. After Buffy (Sarah Michelle Gellar) and Angel (David Boreanaz) capture the vampire Willow, the real Willow takes a look at her vampire-self and comments, "That's me as a vampire? I'm so evil and skanky. And I think I'm kinda gay!"
In the very first episode of Futurama, "Space Pilot 3000," Fry (Billy West) is accidentally frozen and wakes up 1000 years later. Just before he falls into the cryotube, in a blink-and-you'll-miss-it moment, you can see a small shadowy figure under a desk in the Applied Cryogenics office. In the season four episode “The Why of Fry,” it was revealed that Nibbler (Frank Welker) was hiding in the shadows. He planned to freeze Fry in the past, so that he could save the universe in the future. According to co-creator Matt Groening, “What we tried to do is we tried to lay in a lot of little secrets in this episode that would pay off later.”
7. American Horror Story: Coven
American Horror Story: Coven follows a coven of witches in Salem, Massachusetts. When Fiona (Jessica Lange), the leader of the witches, is stricken with cancer, she believes a new witch who can wield the Seven Powers will come and take her place. Fiona then begins to kill every witch she believes will take her place until the new Supreme reveals herself.
During the opening credits of each episode in season 3, Sarah Paulson’s title card appears with the Mexican female deity Santa Muerte (Holy Death), the Lady of the Seven Wonders. And as it turned out, Paulson’s character, Cordelia, became the new Supreme witch at the end of the season.
8. Mad Men
At the end of Mad Men's fifth season, ad agency partner Lane Pryce (Jared Harris) committed suicide by hanging himself in his office. While it was a shock to the audience, the show's writers hinted at his death throughout the entire season.
In the season 5 premiere, Lane jokes "I'll be here for the rest of my life!" while he’s on the telephone in his office. Later, in episode five, Don Draper doodles a noose during a meeting, while Lane wears a scarf around his neck in a bar to support his soccer club. Early in episode 12, Pete Campbell (Vincent Kartheiser) mentions that the agency’s life insurance policy still pays out, even in the event of a suicide.
9. How I Met Your Mother
In How I Met Your Mother's season 6 episode, “Bad News,” Marshall (Jason Segel) and Lily (Alyson Hannigan) are waiting for test results that will tell them whether or not they can have children. While we’re led to believe the title of the episode reflects their test results, it actually refers to the news that Marshall’s father, Marvin Eriksen Sr. (Bill Fagerbakke), had passed away after suffering a heart attack.
Keen-eyed viewers knew this news already because the writers of How I Met Your Mother foreshadowed the death two seasons earlier in the episode “The Fight.” At the beginning of the episode, Marshall said that lightsaber technology is real and will be on the market in about three to five years from now. By the end of the episode, a flash forward reveals what Thanksgiving looks like at the Eriksen family’s home in Minnesota; Marshall’s father is not shown or referenced during the holiday meal.
10. True Detective
During season 1 of True Detective, detectives Rust Cohle and Marty Hart are trying to solve a murder investigation, as they try to identify the mysterious “Yellow King.” The color yellow is used when the detectives are on the right track, but the detectives already met the killer in episode three, "The Locked Room."
When the pair went to the Light of the Way Academy, posted on the school’s sign was a very clever hidden message that read “Notice King,” which pointed to the school's groundskeeper as the killer.
