Neither Harington nor Fallon took the ruse to the heights reached earlier this week by Maisie Williams, who, while visiting Tonight, pretended to let slip that her character Arya Stark gets killed off in the second episode of the upcoming eighth and final season of Thrones.
Carol McSeveney, Textiles Sales Leader, IKEA UK & Ireland, said: "We are flattered that our rugs have featured in Game of Thrones across the years and can't wait to see them making a re-appearance in Season 8". He bought a Jon Snow costume from a commonplace costume shop. The episode will not only cast Kit Harington and Leslie Jones but will also echo the music of American singer-songwriter Sara Bareilles. Keeping that in mind, Fallon challenged Harington to settle some Game of Thrones spoiler questions with a wink meaning yes and a blink meaning no.
