Williams, who plays Arya Stark, took to Instagram to post a shot of her blood-stained runners.
Or will she end "Game of Thrones" in triumph?
Clarke put an image of herself in a field of flowers on her Instagram account at the time.
Maisie Williams gave a Game of Thrones farewell that was straight out of Westeros.
Clarke's post was far more pleasing on the eye than William's blood stained shoes, it showcased Belfast's attractive flowers rather than the show's famous gore.

The resignations came after May's Cabinet formally endorsed her plan for a "U.K. -E.U. free trade area" on Friday. That agreement, at her Chequers country retreat, was meant to kick-start talks that have been stalled for months.
Williams added a few hashtags to her post, including a couple that may provide a clue to the fate of Arya in the upcoming final season: #lastwomanstanding, followed by #barely. "What a joy I've had".
She joked: "No, [Arya] likes red. Here's to the adventures to come #lastwomanstanding #barely #immasleepforthenextfouryears #justkiddingidontsleep".
However, in signature Game of Thrones style, it seems like there's more to just Arya being the "last woman standing". Maisie's revelation could easily mean that the other female characters have been killed.
Fans will have a while to wait to find out if there is any truth to the hashtag, with the show not due to return until 2019.
"That would be bad if I got the ending tattooed on my body, just before the last season came out", she told Digital Spy.
