Alongside the two heartbreaking deaths in the latest Game of Thrones episode 'The Last of the Starks', there was a pretty heartbreaking non-death-related moment too.

After seasons of will-they-won't-they, Jaime Lannister and Brienne of Tarth slept together, satisfying many fans' dreams in the process.

However, it was cut short as quickly as it began upon Jaime hearing that Daenerys Targaryen's forces (and a dragon) had been depleted at the hands of his sister Cersei.

He then leaves in the night to go back to King's Landing, breaking Brienne's heart by telling her that he is hateful just like his sister.

We then see Brienne cry, and the episode's director David Nutter has admitted that he got actor Nikolaj Coster-Waldau to ad-lib a line off-screen to spark the moment.

"When I was shooting Gwendoline [Christie]'s close-up, what I asked Nikolaj to do is, I asked him to say — after he finished his dialogue — tell her, 'I don't love you anymore'," he told Collider.

"And basically, Brienne is such a sensitive person, as is Gwendoline, that that's basically the thing that he's saying… but he's not saying it too directly.

"So I basically had him say it off camera and when he did that, she basically lost it completely and that's the reaction that was actually kind of recorded at that point."

We've already argued that the Brienne storyline in the latest episode is a massive betrayal of the character we've come to know, though Christie has defended the plot.
