Season 1 - Andrea Says Goodbye To Amy
Our first hint that not everybody on "The Walking Dead" was going to make it out alive came in the first season when Andrea's (Laurie Holden) sister, Amy (Emma Bell), is bitten in the neck during a zombie attack.
Hysterical Andrea cries and hugs her sister's lifeless corpse until the corpse suddenly isn't so lifeless anymore, forcing Andrea to put a bullet in zombie Amy's brain.
Season 2 - The Deerhunter
In the season-two premiere, young Carl (Chandler Riggs) is unexpectedly felled by a bullet. The shooting was an accident, caused when Otis (Pruitt Taylor Vince) was out hunting and fired at a deer, not realizing Carl was there. The silver lining of this near-fatal mishap: thanks to Otis's poor aim, Rick (Andrew Lincoln) and the survivors hooked up with Hershel (Scott Wilson) on his fortified farm.
Season 2 - Cowardice And Betrayal
While scouring the walker-infested town in search of antibiotics to prevent Carl's gunshot wound from getting infected, Shane (Jon Bernthal) and Otis are overtaken by a small army of the undead.
Shane shows his true colours when he cold-bloodedly shoots Otis, leaving him as a diversion for the hungry walkers while he makes a getaway. This is the moment when Shane crosses a line that takes him down a very dark path.
Season 2 - Zombie Boo Boo
When the gang goes to get some fresh water from Hershel's well, they discover, well, this.
Just when you think no creature could be more disgusting, the corpulent walker splits in two as they haul it up with a rope, both pudgy pieces writhing around like giant split maggot.
We're still having nightmares.
Season 2 - Hershel's Barn Full 'O Zombies
Hershel had been quite adamant about keeping Rick and his group away from his barn, and Shane discovered why: the country doctor had been capturing walkers and storing them in his barn in hopes a cure would be found that would restore the mindless zombies to their former selves.
Hershel kept them locked up, feeding them the occasional chicken — what could possibly go wrong with this ironclad plan?
Season 2 - A Sad Goodbye To Dale
Occasionally veering toward preachiness, Dale (Jeffrey DeMunn) was the conscience of the group, a voice of reason when tempers flared and a calming influence on everyone.
In fact, it was Dale's keen sense of justice that led to his demise, when he vehemently disagreed with Rick's decision to murder a dodgy outsider named Randall. Angry and pacing in the dark all by his lonesome, Dale is attacked by a stray walker (the same one that Carl inadvertently freed from the mud!) and disemboweled.
Near death when he's discovered, Dale nods his silent assent when Daryl puts a gun to his head and pulls the trigger. For fans of the comics, this moment represents a significant departure from the original storyline, in which Dale stuck around a lot longer, and made viewers realize that if Dale could be killed off, anybody could.
Season 2 - Sophia Is Found
One of the most annoying storylines in season two was the disappearance of young Sophia (Madison Lintz), which led to various members running around hither and yon searching for her — even though common sense would dictate she was a goner.
This storyline paid off when Shane forcefully opened Hershel's barn doors to show the group what their host was up to, and among the walkers to emerge was snarling Sophia.
While Daryl holds back Carol (Melissa McBride) as she tearfully tries to rush toward her undead daughter, Rick takes aim and shoots zombie Sophia in the head.
Season 2 - Sacrificing Shane
After Dale's funeral, Shane coldbloodedly kills Randall, leading Rick to deduce that he's next on Shane's twisted hit list.
When Rick confronts his former best friend, he tries to reason with him but Shane is too far gone. They scuffle, and Rick stabs Shane in the heart. As if that weren't shocking enough, the zombified Shane later rises from the dead and shambles after Carl, who shoots undead Shane in the brain.
Season 2 - Heeere's Michonne!
In the final moments of the season-two finale, viewers got their first glimpse of a hooded, sword-wielding mystery figure trailed by a pair of armless zombies on chains that follow her like dogs.
Viewers' collective response to the introduction of Michonne: "Holy crap!"
Season 3 - Hershel Doesn't Have A Leg To Stand On
As the group tries to take over the walker-infested prison in the season-three premiere, Hershel sustains a zombie bite to the leg. Thanks to some quick thinking and a sharp blade, they're able to hack off the bitten leg before the infection manages to infest the rest of his body.
Given how many characters had already been killed off, the most shocking thing of all was that Hershel survived.
Season 3 - Rick Downs Tomas
Rick doesn't have the warm fuzzies about Tomas, leader of the prison survivors, but his spidey sense really starts tingling when a prisoner gets a deep zombie scratch and Tomas mercilessly murders the guy without a moment's hesitation.
When Tomas becomes increasingly belligerent towards Rick — even shoving a walker at him during a zombie melee — Rick realizes Tomas may be more dangerous than any walker. After the last walker is killed, Tomas tries to justify what he did by shrugging his shoulders and saying, "s**t happens." Rick's response is rapid and lethal when he cleaves Tomas's skull with a machete, a WTF moment if there ever was one.
Season 3 - Born To Blossom, Bloom To Fade
When pregnant Lori (Sarah Wayne Callies) inconveniently goes into labour right in the middle of a zombie prison riot, Maggie (Lauren Cohan) is forced to perform an emergency C-section to save the baby's life. The baby survives but Lori doesn't, dying soon after childbirth.
But the shocking moment comes when it's up to Carl to man up and put a bullet in his mom's brain to prevent her from rising from the dead.
Season 3 - T-Dog No More
During the same prison melee, T-Dog (Iron E Singleton) courageously sacrifices himself to allow Carol to escape a zombie attack, the first time "The Walking Dead" has killed off two beloved characters in the same episode.
Season 3 - The Governor Is Weirder Than We Thought
To the citizens of Woodbury, the Governor (David Morrissey) is their charismatic leader, who's kept their heavily fortified town safe from walkers.
But viewers soon found out the dude has some serious issues — like keeping his zombie daughter locked in the closet and lovingly ogling the collection of decapitated zombie heads he stores in the world's creepiest aquarium.
When Michonne destroyed the Governor's undead daughter and drove a shard of glass deep into his eye, we saw the true depth of his madness — which became far deeper.
Season 3 - The Return Of Merle
After being murdered by the Governor after a failed last-ditch shot at redemption, Merle comes back as a walker.
This leads to the horrifying moment when it's up to Darryl to put his undead brother down for good.
Season 3 - Death Finally Finds Andrea
After The Governor learns of her duplicity, Andrea is locked in a room with newly zombified Milton (Dallas Roberts), who chomps into her shoulder.
When Rick and the others find her later, they realize she's been infected and reunite her with her sister (who died in season 1).
Season 4 - The Governor Gets Ahead
Viewers may have thought that Hershel, held prisoner by the Governor, would be saved in a last-ditch rescue, but that was not to be.
Instead, the country doctor and constant voice of reason was decapitated by the Governor by — adding insult to injury — Michonne's sword.
Season 4 - Terminus Lives Up To Its Name
When the gang finally makes it to Terminus, they soon come to the horrific conclusion that the residents of this survivor's community have turned to cannibalism — and they're on the menu.
Season 4 - Lizzie Loses It
Carol discovers it was little Lizzie who was feeding rats to the zombies, and is disturbed to learn the reason: Lizzie thinks walkers aren't bad, just misunderstood.
To prove it, she murders her own sister, just to prove that she'll come back as the sweetest zombie ever.
Realizing the kid has completely lost her marbles and threatens to endanger everyone, Carol takes her out into woods and releases the little girl from the horrors of the present day.
Season 4 - Rick Finally Rages
Rick Grimes has lost his family, awoken to a zombie apocalypse, been witness to not only his best friend dying, but also his wife. It's amazing that the cool-as-a-cucumber cop hasn't raged sooner.
In a frame-by-frame remake of one of the most brutal moments from the comic, Rick explodes with rage during his confrontation with The Bandits ...tearing out the throat of leader Joe ...with his teeth.
Season 5 - Bob Becomes BBQ
Bob has been abducted by the survivors of Terminus after Rick and the crew escape and trash the place, and is privy to watching them chow down on some barbecue.
As the camera pans out, we come to the horrifying realization that Bob's missing a leg, which is spit-roasting over an open fire.
Season 5 - Eugene Comes Clean
Mullet-headed Eugene gave everyone hope, declaring to have a cure for the virus and claiming to know what caused it.
But things took a rough turn for Eugene when he revealed he'd been lying the whole time — and there's no cure that he knows of — leaving fan favourite Abraham to go into a tailspin of despair.
Season 5 - Dawn Goes Under The Knife
One of the series' most beloved characters came to a shocking end in the midseason finale of season 5 when creepy officer Dawn Lerner slashes her throat in the midst of a showdown with Rick's group.
While it seemed unlikely she survived (she didn't), that didn't prevent distraught fans from setting up a Change.org petition urging producers to figure out a way to bring her back.
Season 6 - Meet Shiva
Carol gets the surprise of a lifetime after Morgan saves her and brings her to the Kingdom.
Not only does she meet King Ezekiel, but also his pet tiger Shiva.
Season 6 - Glenn Dies...Or Does He?
We doubt there was a dry eye in the house when Glenn, getting dragged down by Nicholas, fell into a zombie hoard.
The fans were divided. Some praised the show from stepping away from the comics in how they said "goodbye" to Glenn, while others were miffed our favourite pizza delivery boy would never meet the big, bad Negan and his beloved Lucille.
It wasn't until the midseason premiere that we found out, Glenn was alive and well, having crawled under the dumpster to hide from the hoard.
Season 6 - Carl Loses An Eye
A moment that fans of the comic have been waiting for, Karl finds himself in the middle of a domestic battle gone wrong, when a bullet intended for Rick pierces his eye.
The shocking moment happened after not one, but three characters lost their lives in a walker hoard and immediately before all of Alexandria is forced to fight for their lives.
Season 6 - Eenie, Meenie, Miny, Moe
The season 6 finale of "The Walking Dead" was one for the books.
Rick and his friends were captured by Negan, who proved how ruthless he could actually be, by taunting the group about who he was going to beat to death with his bat.
Fans of the comics knew this was coming, and they had an idea of who would be on the receiving end of Lucille's wrath, but no one could prepare themselves for the way the chilling scene would play out.
Season 7 - Bye, Bye Abraham
In a wicked turn of events, Negan's sick game ended with a blow to the head of Former Sgt. Abraham Ford, who managed to tell the series' big bad exactly what he thought of him (not to mention throw his home girl Sasha a peace sign) before he succumbed to the wrath of the Saviours' leader.
Season 7 - Glenn Gets It
After saving himself from a zombie hoard by crawling under a dumpster in season 6, Glenn finally meets the end at the hands of the tyrannical Negan.
Having already killed Abraham (Rick's punishment for killing some of the Saviours), Negan kills Glenn after Daryl charges him following his friend's death.
Season 7 - Rick's Battle Royale
If you thought that well zombie was bad, season 7 basically told fans to "hold its beer" before producing one of the scariest zombies we've seen - clad in spiked armour!
It's one thing to find yourself pushed down a ditch in a landfill, it's a whole other thing to find yourself going head to head with this guy.
Season 7 - Negan Puts Karl In An Uncomfortable Position
"The Walking Dead" has a lot of uncomfortable scenes, but this moment between Negan and Karl is hard to watch.
As Negan says, "it's easy to forget that you're just a kid" and it's true. The scene rings true, reminding us that Karl has seen a lot in his time on the show, and that his relationship with Negan is very dangerous.
Season 7 - Richonne Take It To The Streets
Think getting cut off on the highway is bad? Rick and Michonne took that to a whole new level when they decimated walkers in one of the coolest (or grossest) mass killings we've seen on the show.
Two cars and one long, thin pole made quick work of a hoard of walkers in one foul swoop.
Season 7 - Shiva Saves Karl & Rick
We're not going to lie, we kind of forgot that "The Walking Dead" had a tiger until this "oh s**t" moment when Shiva comes to the rescue, saving Karl from Negan's rage.
Oh and just in case you're wondering, yes, the BTS of shooting this is hella funny.
