Spoilers for the Game of Thrones finale can be found in this article!
Game of Thrones' Season 6 finale "The Winds of Winter" featured a slew of moments that we'll be talking about for months. One of those moments featured Cersei going full Mad Queen and taking out her enemies the Sparrows, as well as the Tyrells, with the wildfire that had been stored under the city. While that moment was insane, it paled in comparison to what happened after, when Cersei took revenge on Septa Unella, who had shamed the queen over the past couple of seasons. Apparently, when that scene was initially envisioned, it was written as being much worse than it played out on the small screen. Here's what Lena Headey---who plays Cersei on Game of Thrones---had to say:
It's so filthy. It's so great. Everybody's witnessed what happened with the two of them. I don't think people will be able to help going, 'Yes!' But it's so depraved, it's brilliant. The scene was meant to be worse, but they couldn't do it. This is like the tame version. It's pretty bad still though. I'd take being exploded in the Sept over that any day.
That would have been the perfect opportunity for a follow-up about just how depraved the scene was supposed to be, but Lena Headey didn't elaborate to EW about what exactly the showrunners had planned. Instead, we got a scene in which Cersei introduced Septa Unella to The Mountain. In the past, The Mountain has raped, killed and otherwise abused his foes, and the new zombie version of the character is even scarier, as he actually took a Sparrow's head earlier in Season 6 and ripped it off in front of a whole group of the faith militant.
We may not know exactly what the monster version of The Mountain did to Septa Unella, but it is clear that Cersei wanted her to suffer and left her at his mercy. Considering Lena Headey's comments, it was presumably not a pleasant fate, even if we only got to see Cersei walk out of the room, leaving the mismatched couple behind her. It makes us wonder, however, what the script initially called for, what the show may have filmed and how the creative team instructed Lena Headey to behave during the scene.
