Great TV shows are often punctuated with OMG moments— those shocking twists you never saw coming which hit us like a freight train full of plutonium. While some shows are content to sit back and entertain the glazed-eyed masses with recycled punchlines and canned laughs, the shows on this list put the dramaaaaa in drama.

(Also, since this is a list of shocking TV moments, it should go without saying that there are spoilers here, but, just in case, here it is: SPOILER WARNING).

Lost: What’s in Jeremy Bentham’s Coffin

We spend season five of Lost watching good ol’ Locke traipse around happy to be back on the island. We think he’s survived being murdered, that he’s a-okay, and that the island is in good hands… until we see what’s in “Jeremy Bentham’s” a.k.a Locke’s coffin. Whoops! It’s his body! Turns out the real Locke is dead, begging that all-important question: who the hell has been running around looking all Locke-y for the last twenty plus episodes?

The Walking Dead: A Life for a Life

By the time season three of The Walking Dead rolled around, most people were sick to death of Lori being stupid and a bad mother… but then you see how little her son and husband care about her and you actually start to care, which is the perfect time for them to finally axe the chick. Lori’s death isn’t a surprise, it’s the fact that she dies so brutally, and so early in the third. The surprise comes in how quickly into the season she is killed off and the way she dies. I mean, she dies from a hobo-style c-section, prompting poor Carl to have to put one in her brain ‘lest she rise back up. And then, when Rick goes back for her body later, there’s nothing to be found but one very full-looking zombie. YUCK!

Buffy the Vampire Slayer: Tara’s Death

Tara may not be an original cast member of Buffy the Vampire Slayer, but she earned a spot in our hearts as one the Scoobies. A powerful witch in her own right, and girlfriend to Willow, Tara was quiet, shy, and probably the nicest out of all the Scooby Gang, so seeing her get shot and killed was like getting hit with an eighteen-wheeler, then flattened by a steam roller, and then pooped on by a murder of crows. Her death comes at the sweetest time too, just to add an extra twist of the knife. Tara and Willow had just reunited when, out of nowhere, we hear a crack and some blood spatters Willow’s face. From there the audience feels exactly what Willow does: shock, disbelief, and confusion (although most of us skipped the insane, world-ending rage part).

Game of Thrones: Take your pick.

The Red Wedding. The Mountain Vs. The Viper. The fate of Ned Stark. Author George R.R. Martin doesn’t pull any punches with his brutal fantasy series, and the HBO show of the same name sure doesn’t either. If you’ve yet to dive into this unpredictable, harsh, and masterfully-crafted series… know that things are going to get ugly, and often when you least expect it.
