If you haven't seen the last episode of season seven, be warned that there are some spoilers here. You might want to click away. Seriously, do not come crying to me, saying I ruined the show for you. What kind of fan are you if you haven't seen it yet, anyway?
Just because Game of Thrones season seven ended last month, don't think that the fan theories have in any way slowed down. If anything, they've simply gathered momentum.
Yup, the eighth and final season may be a more than a year away but fans are still trying to piece together what's going to happen next and how the show will end.
One popular theory is that the Night King is none other than Bran Stark, an idea which has gained so much traction that even Isaac Hempstead Wright, who plays Bran, has addressed it in an interview with Vulture.
He said: "I think it's less that they're the same person and more that they're two of the ancient beings of Westeros.
"The Three-Eyed Raven has been around for God knows how long, and White Walkers have been reported since the beginning of time.
"As we've seen, they were created by the Children of the Forest, so we can't get much more ancient than that. Perhaps we can think of it as these are two characters with a huge amount of power, but one is a Frankenstein's monster, who is driven by nothing but hatred and violence.
"Then there's Bran, who uses his powers for good."
Eagle-eyed viewers had previously noticed that when the Night King destroyed The Wall in the north, the White Walkers appeared to walk off in the shape of a direwolf - the House of Stark sigil.

Ok, so it looks like Bran - sorry, Isaac - seems to have pissed all over that theory, but is that all just to throw us off the scent?
Plus, there's a good chance that even the actors don't know how the final season is going to pan out yet.
So we're back to guessing, then?
