As Game of Thrones imminently returns to our lives, we're busy speculating on what the last two seasons are going to bring. There are many, many fan theories on the internet - but here's a rundown of the ones that could still come true.
1. Tyrion and Daenerys are siblings
Also known as "A+J=T", the theory states that Tyrion and Daenerys are actually half brother and sister. This would be thanks to a union between Tyrion's mother Joanna Lannister and The Mad King (Aerys Targaryen).
The two were together around nine months before Tyrion was born, after she visited King's Landing to celebrate Aerys's tenth year on the Iron Throne. And let's not forget Tywin's lifelong hatred of his son, and his final words to Tyrion: "You're no son of mine."
Now that we've witnessed Tyrion having an easy-going bond with the dragons, could this mean that he has some Targaryen blood inside him?
2. Sansa is pregnant with Ramsay's child
The theory began after Sansa tells Littlefinger: "I can still feel it [...] I can still feel what he did in my body standing here right now."
Fans have debated whether she is referring to a literal baby inside her rather than physical and emotional damage. Jon Snow later commented on her new large coat – to accommodate her child? – and that she didn't want to eat the Night's Watch food.
It would be a horrible turn of events.
3. Sansa will betray Jon
Little finger has already been meddling, pointed out to Sansa how Jon is really just her half-brother, and thus she is the true Stark heir and leader (true, Bran's still around, but Sansa doesn't know that). Sophie Turner has hinted that fans might no like what Sansa gets up to. saying: "This season, it's really interesting. I think she might be a little more unlikeable, because she finally has this power..."
4. Jon will kill Daenerys
As the original book series was named A Song of Ice and Fire, it's fair to assume that the end game will involve Jon Snow (Ice) and Daenerys (Fire) in some way. Whether they'll be together or against each other remains to be seen, but one theory is that Jon will be forced to kill Dany.
Supporters of the theory predict that far from being its saviour, Dany will follow in her father The Mad King's footsteps and become a maniacal force, bringing ruin to the Seven Kingdoms. To defeat her Jon Snow will awaken an Ice Dragon to do battle with her dragons. Still with us?
5. Jaime will kill Cersei
Previously, fans theorised that Jaime Lannister would be forced to kill his sister/lover to stop her from unleashing the wildfire in King's Landing, much like he did with the Mad King.
As we now know, Cersei carried out her plan without being stopped. However, Jaime returned and looked on in horror at what she had done, and how it had led to the death of their last child, Tommen, whilst securing her the Iron Throne.
In both the show and the books, Cersei is told in a prophecy that she will be strangled to death by "the Valonqar". In Valyrian, this translates as "little brother" or "younger sibling". While you (and she) might assume this was her hated younger brother, the dwarf Tyrion, it could actually mean Jaime, who was born just after his twin sister.
6. The whole story is being written by a Maester in the library
In the season 6 finale, we noticed an object inside the library at the Citadel that looked very similar to something we see in the opening credits.
Known as an astrolabe, the device is used to track the movement of stars and planets.
When Sam arrives at the Citadel, a Maester greets him wearing a pair of spectacles. When you look at the credits again, it's pretty clear that someone is viewing them through lenses.
It would seem hard to deny that the credits are meant to be a Maester's view of events.
So perhaps the final ever scene will be an elderly Sam looking up from the book that he's written, a history of the great war? A Song of Ice and Fire, if you like.
George RR Martin has compared himself to Sam. When asked what character he's most like in 2014, he said: "I would probably be Samwell Tarly. I love Sam, too. He's a great character."
Let's all just take the hint.
