I know fans of the book get very self righteous when you bring this moment up, and often feel compelled to say something stupid like: Well, if you think THAT was bad, wait until (spoiler spoiler spoiler). I think those people should be tossed out a window by Jamie Lannister, no matter their age.
I understand that the fans who have loved this series for years look at us all like tourists now, but screw them. Even if you knew the Red Wedding was coming on Game of Thrones, it was still shocking. You can’t deny that.
For those who missed it, the Red Wedding was the trap set by Walder Frey for the Stark’s breaking the marriage pact between House Stark and House Frey. Just the simple line of “The Lannisters send their regards” right as they kill Rob was shocking enough, but seeing a pregnant woman get stabbed over and over in her belly, well, that was very fucked up.
On top of all that, Rob’s mother had her throat cut and most of his troops were slain. Really happy stuff. It was brutal, gut-wrenching violence, and it is EXACTLY why we love this series so much. No one is safe. Ever. Just like in real life.
