SPOILERS: Major spoilers from the most recent season of "Game of Thrones" follow.

There are fans out there who would gladly watch new "Game of Thrones" episodes until the day they die. But as Maisie Williams -- loved for her tough-as-nails portrayal of Arya Stark -- told Variety in a new interview, "Good things must come to an end or they're not good anymore."

"It doesn’t last forever and we’ve done what we came to do, it’s time to wrap this up," Williams explained on the impending end of the series. "It will have the ending it was always supposed to have, and that’s very special. David and Dan started writing this show knowing the end, not knowing that it might actually come around and we might be allowed to make that many [seasons] — at the beginning we were just willing to make one [season]. They started this with an end in sight, and so it’s exciting to be closing it… I’m just excited to see everyone again."

Hot off of its sixth season, "Thrones" is hoping to keep up its quality as it surpasses author George RR Martin's source novels in the narrative in its upcoming seventh year and its eighth season in 2018, which will be its last.

Elsewhere in the interview, the 19-year-old actor -- who has deftly navigated Arya's journey from scrappy nobility to blind assassin to vengeful protector of her family's name -- comments on her Emmy nomination and the thrill of finally giving the despicable Walder Frey what he deserved.

“There’s this one take where we did a close-up," she remembers, "and I slit his throat and he’s bleeding out and I got this perfect little speck of blood just above my collarbone on my neck. It wasn’t like Tarantino blood everywhere, just this one little speck, and it happened naturally, it happened realistically, and you literally couldn’t have flicked a bit of blood on better.”

It's those kind of comments that will make us miss Williams' performance as Arya. Luckily, Martin still has two books to write, meaning her adventures won't be over for quite some time.

"Game of Thrones" returns to HBO for its truncated seven-episode seventh season on April 21, 2017.
