*Obviously, colossal spoilers abound if you're still catching up and/or have been avoiding trailers/theories about the final episodes*
It's the most popular TV show in the world - and it's about to entirely take over your life (or, at the very least, your social media timelines) for the next six weeks.
The final season run might be short - but the episodes are not. The first two episodes of season eight are 54 and 58 minutes long respectively; episode 3 is an hour long, and episode four is 78 minutes. Then the final two episodes - with the finale airing on 19 May - are 80 minutes long apiece.
Naturally, hardcore fans are feverish in their desire to find out what happens, and seeing as the show's plot has now overtaken George RR Martin's source books - and there's been an 18-month gap between the penultimate season and this - the internet is groaning under the weight of theories about what's going to happen, who's going to live and die, and who will ultimately end up on the Iron Throne.
So what are the big theories going into the home stretch? We've sifted through a lot of them, and picked out five of the wildest, most entertaining, and most intriguing ideas out there. In no particular order:
1. Bran Stark is the Night King
This is one of the most enduring theories, even though - or perhaps because - it has been so fulsomely disputed by actor Isaac Hempstead Wright, who plays him. And certainly there are fans out there who don't buy that Bran/The Three-Eyed Raven - through a fateful mix of time travel and his psychic powers - is the villainous original White Walker.
This theory opens out to include the prospect that Bran's well-intentioned but calamitous meddling with the past has led to this entire mess. We already know his time travelling messed with Hodor's mind, the sole silver lining of which was this amazing real life reaction from Isaac:
There's now a chance, as one Redditor posits, that Bran's attempts to warn King Aerys II Targaryen about the future threat of the White Walkers (via whispers in his head) actually drove the man insane - turning him into "the Mad King". Yet another (albeit connected) theory is that Bran's time travelling resulted in him being the one who originally built the Wall.
Look, who knows what to think anymore? But what fans should expect is that Bran will likely be absolutely central to the resolution of the series - possibly by 'warging' into a dragon.
2. Jon Snow gets another identity
The name of the legendary hero Azor Ahai (aka The Prince/Princess That Was Promised) looms large in Game of Thrones mythology. With the aid of a sword named Lightbringer, Ahai "defeated the darkness" thousands of years before - and now he's rumoured to be making a comeback, reincarnated in another form, ready to save Westeros from the White Walkers. But which GoT character will end up channeling him?
Though lots of fans don't buy this theory, one major knock-on effect if the Jon/Azor theory proves correct is that his lover/ally/aunt Khaleesi, Daenerys Targaryen, has to die - because of a huge sacrifice being required in order for the prophecy to be fulfilled...
3. Khaleesi is the final season's big hero - and, possibly, villain
There are lots of reasons Daenerys could be toast by series' end - and lots of ways for it to happen. But if you're a betting person, it's probably equally likely that she survives - and wins the whole thing. As with Jon Snow, there are many fans who believe she is the reincarnation of Azor Ahai, and the one who will save everyone from the White Walkers.
4. Jaime kills Cersei
Cersei Lannister is the brutal, conniving, power-hungry monster that we all hate to love, and one of the most popular theories about the upcoming series is that she won't make it out alive.
Fans point to a prophecy that Cersei was given as a child, which, among other predictions that have since come to pass, says a "younger brother" will choke her to death. Both Tyrion and her twin/lover Jaime are her younger brothers - and the penultimate season ended with Jaime breaking away from his sister's plans, suggesting that he may end up being the one to finish her off.
5. Lady Stoneheart and other Stark warnings...
Speaking of, the fates of the Stark sisters, Arya and Sansa, are a big focus for some fans in the run-up to these final episodes.
Let's start with Arya. One of the latest theories about her comes from a brief scene at the start of the teaser trailer that shows her running, frightened, through what appears to be a dark passageway in Winterfell. It could be any number of things that has put the frighteners on her, like a rogue White Walker for instance, but some think Arya has encountered the reanimated corpses of dead family members. The theory goes that the Night King has brought some deceased Starks back to life - so maybe Arya has seen her dead father Ned, or brother Robb?
There's another, grimmer theory about Arya doing the rounds - that she's already dead. The explanation goes that Arya died during her vicious battle with the Waif, and that the Waif has been wearing Arya's face, impersonating her, ever since...
As for Sansa, she's had a truly horrendous time throughout the show so far - sometimes controversially so - but at least one theory has a happy ending for the character (well, as 'happy' as anything can get in Game of Thrones). Sansa, some argue, will become Queen of the North in Winterfell - but only if Jon Snow dies - and will forge a lasting peace with Daenerys.
All will be revealed soon enough. In the meantime, feel free to add your own theories and predictions in the comments below.
