Game of Thrones is set to land on April 14, meaning we've got less than two weeks until we'll be returning to Westeros and on our way to getting a final conclusion to the hit fantasy series.

The HBO show is so popular at this point that you pretty much have to watch it the night it premieres or you'll get spoiled on Facebook, Twitter, Instagram, or just in the water cooler conversation at work.

The stars of the show have to be particularly careful not to let anything slip. They've spent years with the characters, and when there are millions after you hoping for any tidbit of information, it can be easy to let something slip.

Honestly, if I were them, I'd lock myself up at home for the next few weeks just to be extra safe - but that's not a luxury they can afford when they have to jump on the promotional tour to publicise the new show (as if it needs it at this point). Maisie Williams, who plays Arya Stark, recently appeared on The Tonight Show Starring Jimmy Fallon to talk about the show, when she dropped a spoiler - or at least, it looked like she did.

First of all, the 21-year-old actress spoke about her favourite moments playing the youngest Stark daughter. For anyone who isn't up to date, there's some spoilers in there for sure, but it got a lot heavier once the conversation turned to the upcoming eighth season.

"I've decided to just keep a tight lip on everything," Williams said. "HBO have sent out a lot of memos recently about just saying nothing. So, there's really nothing I could say, they would absolutely kill me."

After Fallon continued to beg, asking for "one little spoiler, one little hint - a crumb is all I ask," before switching to his best Oliver Twist to ask "m'lady, just a crumb is all I'm asking for."

Williams sounds like she's deflecting, but then she drops something pretty major, revealing: "During shooting, like, the final days were really emotional saying goodbye to all of the cast because when I found out that Arya died in like the second episode I was..."

This would've been easily spotted as a gag, if it wasn't for how well Williams sells it. A split-second later she 'realises' and begins to shake, looking genuinely upset and fearfully asking if they could edit that out. He tries to reset the moment and act like nothing happened, but she rushes off stage in distress. Fallon steps it up a notch by looking genuinely awkward and concerned before he heads off stage to find her.

That's when they reveal it's all just one big April Fools joke... something those in the audience were undoubtedly pretty freaked out over, at least for a moment.

Now at least she's covered and made us all safe so that Arya can die in the first episode.
