Obviously we all know Game of Thrones isn't shy of a death or twenty, and while some have been more elaborate than others, we've never really considered which was the most expensive. Ned's prosthetic head from season one? One of the many red wedding deaths?
Nope, it was actually Ser Meryn Trant, a knight of King Robert I Baratheon's Kingsguard, who was one of the names on Arya Stark's famous list and who she brutally murdered in season five.
The gruesome death saw Arya stab him in the eyes, chest and the back before slitting his throat. She doesn't do things in half, that Arya.
Showrunners D.B. Weiss and David Benioff told fans this at an event at 2017 SXSW Festival in Texas during the week, and when asked why it was so expensive: Benioff simply said: "She couldn’t really poke out his eyes".
Fair enough, but didn't the same thing happen to Oberyn Martell? But shurlookit, we'll take their word for it.
