Spoiler alert: they spoiled Stannis last night. Well, someone did.
"Maybe we should have tried the leeches first..."
IF YOU HAVEN'T SEEN THE EPISODE AND YOU ARE READING THIS, YOU ARE CLEARLY NOT SOMEONE WHO HEEDS SPOILER WARNINGS. NEVERTHELESS, SPOILERS.
Season 5 of Game of Thrones has seen a series high for departures from George R. R. Martin's books, earning showrunners David Benioff and D.B. Weiss their share of both criticism (Sand Snakes) and praise (Hardhome). So, many assumed that last night's horrific events involving fan favorite Shireen, Princess of the House Baratheon, were also concocted by D&D. Well, put down your Internet pitchforks, people. It wasn't their idea, and it had to happen, as they explain in this "Inside The Episode" segment that aired after last night's hard-to-unsee events. (The clip also covers the rest of the episode, so at least you'll get some Drogon to cheer you up.)
I'll let them explain why Stannis's personality made this outcome inevitable, but the main takeaway is this was George R.R.'s idea and likely [spoiler?] a scene from Book 6. Presumably a chapter from Stannis's perspective that ends with him saying "I hope no one made the mistake of liking me, because I bet this would be very disappointing." How bad was it? It was make-you-forget-about-that-horrible-pedophilia-scene bad. That bad.
In retrospect, it's amazing we even considered it not being George's handiwork. In George R.R. Martin's universe, being a genuinely good person who could really make the world a better place should be grounds to commit someone for suicidal tendencies.
