6. Joffrey is poisoned (GOT Season 4, Episode 2)

“I’d hate to die like your son,” Lady Olenna Tyrell tells Jaime Lannister, in her stunning Season 7 confession. “Clawing at my neck, foam and bile spilling from my mouth, eyes blood-red, skin purple.” The poison effectively choked Joffrey of oxygen, triggering violent convulsions as he unsuccessfully gasped for air. So desperate were his attempts to breathe that the blood vessels in his eyes and nose burst. Worse yet was the evident panic. Surrounded by guests at his own wedding, Joffrey would die alone, unable to even summon help. The terrified, lifeless head of the poisoned boy king is one of the show’s most enduring images.
