“I wanted Arya to kill Cersei even if it means [Arya] dies too,” Williams said. “Even up to the point when Cersei’s with Jaime, I thought [while reading the script], ‘He’s going to whip off his face [and reveal it’s Arya]’ and they’re both going to die. I thought that’s what Arya’s drive has been.”
Cersei had been on Arya’s kill list since season one and this ending certainly would have been a dramatic alternative, given it would have used Arya’s face theft skills (her coolest trick after the Night King-killing knife drop) and would have given Cersei a much more shocking death scene than perishing under rubble.
As it turns out, Headey had the same idea in mind, too, stating that her finale was a bit of a comedown from how she’d hoped Cersei’s story would end.
“I lived that fantasy until I read the script,” Headey said. “There were chunky scenes and it was nothing that I had dreamt about. It was a bit of a comedown and you have to accept that it wasn’t to be.” Headey did admit, however, that there was “something poetic” about the way things end with her and Jaime.
