War finally arrived at Winterfell as Game of Thrones season 8 episode 3 showed us the battle between good and evil, the living and the dead.

WARNING: Spoilers

One of the greatest gifts HBO has given Game of Thrones fans this season is a new behind-the-scenes series called The Game Revealed.

Since season one, Thrones has finished each episode with a short featurette taking us inside the episode, but The Game Revealed is that blown up.

GAME OF THRONES RECAP: season 8, episode 3

Thanks to these extra-long videos, we know George Lucas directed a Jon Snow (Kit Harington)/Daenerys Targaryen (Emilia Clarke) scene in episode 1, and Tormund Giantsbane actor Kristofer Hivju went so hard during the Battle of Winterfell there are takes in which the character dies.

However, the biggest clue in The Game Revealed may be what HBO wants covered up. While many actors, like Emilia Clarke, Joe Dempsie, and Nikolaj Coster-Waldau, show up in costumes we haven’t seen yet (signalling they survive a bit longer), Sophie Turner, Maisie Williams, and John Bradley are wearing smocks to hide their later episode costumes.

Why are some actors’ costumes being covered up in these featurettes? What could Sansa Stark, Arya Stark and Samwell Tarly’s costumes possibly spoil?

Let’s back up and talk about what clues these interstitial cast interviews are already giving up for the final three episodes.

Ahead of the Battle of Winterfell, it did occur to me and others these interviews confirmed a number of characters would survive the fight against the Night King. Gwendoline Christie, Joe Dempsie, Sophie Turner, Maisie Williams, John Bradley, Tyrion Lannister actor Peter Dinklage and Grey Worm actor Jacob Anderson all are being interviewed in a sunny location very different from the frigid north. It looked like they were all in King’s Landing. Nikolaj Coster-Waldau even appears in a Lannister-coloured leather tunic in a room that looks like the Red Keep (suggesting Jaime goes back to Cersei’s side). It occurred to me, but I didn’t want to assume, HBO hadn’t merely set up these interviews as red herrings for clue-consuming weirdos like me.

Now that we know all of these character do survive the Battle of Winterfell, it’s safe to conclude that, yes, all of these interviews take place on-set in King’s Landing. We know from this week’s teaser Daenerys is sailing south with her forces to face Cersei Lannister (Lena Headey). So Gendry and Brienne are going to wind up south in fancy new outfits. Great. Good for them. Arya Stark should get her new boyfriend a hot leather tunic.

Still, the question remains: Why are three actors being forced to wear hideous smocks over their outfits? America’s Next Top Model fans will know the reality show forces its contestants to wear their hair in towels when they don’t want to reveal a major makeover before it happens. The logical explanation is Sansa, Arya, and Sam’s outfits are going to reveal some major twist — something even bigger than who lives and dies in the Battle of Winterfell.

Why would HBO think it’s OK for Game of Thrones fans to know certain characters make it to King’s Landing but not what they’re wearing there? The only answer I can come up with is Sansa, Arya, and Sam’s outfits might reveal Jon Snow’s final fate. By this, I mean, if he becomes king in his own right or forms an official alliance via marriage with Daenerys or (gulp) Cersei.

Sansa, Arya, and Samwell are Jon Snow’s inner circle at this point. They are ride or dies and will (begrudgingly) follow his lead from hereon out. Should he take the throne as Aegon Targaryen VI, you can bet the three of them will be outfitted in some sort of spectacular duds that show the unity of the Targaryen/Stark lines. Should he marry either a Targaryen or a Lannister to secure everlasting peace, then they might also be wearing some kind riff on red, black or gold.

Otherwise, why bother to cover up Sansa’s latest gown but not Daenerys’s? What spoilers are in the clothes?

The fourth episode of Game of Thrones will air next Monday on Foxtel at 11am and 8:30pm. Keep an eye out for news.com.au’s recap and podcast analysing the epic ode.
