For Williams, it appears this tattoo is deeply personal — as opposed to a reference for Game of Thrones (of which she has two). In honor of the show's final season airing this April, several actors in the ensemble cast, including Sophie Turner and Emilia Clarke, have commemorated their time together with Westeros-inspired ink. This tattoo likely tells us more about Williams than Arya Stark — as much as we'd love any and all finale teasers. We'll just have to wait 'til April 14 for that. We reached out to Dr. Woo for more info and will update this post when we know more.
