'Game of Thrones' Cast Rocks the Red Carpet for Final Season Premiere

"Mmm, should be Jon though really, shouldn't it?" he allegedly told her.

When your girlfriend comes home from work and tells you she just saved the world, would your first reaction be "maybe some other guy should have done it"?

That's the reaction Maisie Williams got when she told her boyfriend she was going to be the one to finish off the Night King, the actress revealed to EW.

After finding out in a 2017 table read that Arya Stark would be the hero of "Game Of Thrones'" pinnacle moment, his reply was "Mmm, should be Jon though really, shouldn't it?"

The actress described to the magazine the moment she found out she would land the killing blow, admitting she thought fans β€” like her boyfriend, apparently β€” would hate the idea.

"It was so unbelievably exciting," she said. "But I immediately thought that everybody would hate it; that Arya doesn't deserve it."

"The hardest thing is in any series is when you build up a villain that's so impossible to defeat and then you defeat them. It has to be intelligently done because otherwise people are like, 'Well, [the villain] couldn't have been that bad when some 100-pound girl comes in and stabs him.' You gotta make it cool," she continued.

"And then I told my boyfriend and he was like, 'Mmm, should be Jon though really, shouldn't it?"

Indeed the following day after the episode aired fans weren't happy; not with the episode, but at Maisie's boyfriends reaction.

While the 22-year-old did not name said boyfriend, she was dating Ollie Jackson from 2015 to at least July of last year, which was the last time she appeared on his social media accounts; the pair have not been seen together since. Maybe she already took her fans' advice!

Maisie herself soon came round to the idea of taking out the Night King and created one of the badass-est moments in a show already jam-packed with them.

"When we did the whole bit with Melisandre, I realized the whole scene with [the Red Woman] brings it back to everything I've been working for over these past 6 seasons β€” 4 if you think about it since [Arya] got to the House of Black and White," Williams said.

"It all comes down to this one very moment. It's also unexpected and that's what this show does. So then I was like, 'F--k you Jon, I get it'."

Kit Harington himself admitted he was surprised, but pleasantly.

"I was surprised, I thought it was gonna be me!" he said. "But I like it. It gives Arya's training a purpose to have an end goal. It’s much better how she does it the way she does it."

"I think it will frustrate some in the audience that Jon's hunting the Night King and you're expecting this epic fight and it never happens β€” that's kind of Thrones. But it's the right thing for the characters. There's also something about it not being the person you expect. The young lady sticks it to the man."

Director Miguel Sapochnik explained how they pulled off the stunning twist: "I thought, 'Hmm, if I see Arya running then I know she’s going to do something'," he said. "So it’s about almost losing her from the story and then have her come in as a surprise and pinning all our hopes on Jon being the guy going to do it β€” because Jon’s always the guy.

"So we follow Jon in a continuous shot I want the audience to think: 'Jon's gonna do it, Jon's gonna do it...' and then he fails. He fails at the very last minute. So I'm hoping that's a nice switch that no one sees coming."
