(CNN) — Note: This post contains spoilers for the June 2 episode of HBO's "Game of Thrones."
The penultimate episodes of "Game of Thrones" have always left fans talking, but "The Rains of Castamere" may have taken the red wedding cake.
Sunday's episode not only killed off the King in the North and fan favorite Robb Stark (Richard Madden), but also his mother Catelyn (Michelle Fairley) and, most brutally of all, his pregnant wife Talisa (Oona Chaplin).
The depiction of the "Red Wedding" (as it's known in the books) has the power to elicit a strong reaction that even the creator of the TV show didn't know how to handle.
"In the book, when the band starts playing 'Rains of Castamere,' you know something bad is going to happen," co-showrunner David Benioff told EW.com. "It's the strongest physical reaction I've ever had to reading anything."
Yet the hidden benefit of such an intense episode, said Benioff's cohort, Dan Weiss, is that it's "the kind of thing that hammers home that everybody's life is precious and precarious. When you can't take for granted that a character you love on the show is going to be around forever, it makes you pay more attention to them."
Indeed, fans of the series nearly took down the Internet with their emotional reactions to Sunday's "GOT." The response was so overwhelming that there's now a Twitter account pooling together all of the outcry called @RedWeddingTears.
However, George R.R. Martin (the author of the books the TV series is based on) believes it's important to feel this passionate about the many characters that make up the fantasy series.
"You should care," Martin also went on to tell EW.com. "If somebody dies and you just go get more popcorn, it's a superficial experience isn't it?"
