In the divisive final season of the fantasy epic, a shocking twist saw Williams’s character Arya Stark kill The Night King during the Battle of Winterfell, effectively naming her as The Prince That Was Promised, a title that many viewers had presumed would go to Jon Snow.
Harington was just as shocked by this ending as fans, as Williams revealed in a new interview with The Hollywood Reporter.
“Kit expected it to go that way,” said Williams, “and he even said, ‘It was going to go that way. Someone told me in season three that I was going to kill The Night King.’
“And then, he read the script, and it was Arya the whole time.”
She added: “Yeah, I think it would’ve been too obvious. I’m glad that it was Arya, honestly. I think I had the best storyline of the final season.”
Williams can currently be seen in Two Weeks to Live on Sky One alongside Fleabag’s Sian Clifford.
