Are you up to date with the eighth and final season of Game of Thrones yet? If you are, you're probably - like the rest of us - up to your neck in fan theories and guessing games, not to mention eager to discover who will eventually sit on the Iron Throne as ruler of Westeros.
However, before we get to that there is a bigger battle to take place, the final showdown between the living and the dead.
The army of the dead is, as everyone knows, marshalled by the Night King. He was created by the Children of the Forest and has been the subject of much speculation and thought regarding who he was, why he was created and what he wants.
Now, one of the writers has cleared things up just a little bit.
Remember the symbol that the Night King leaves about the place? It's sort of a spiral. We've seen it a few times before - once in the very first episode at the Fist of the First Men, and once more at the creation of the Night King surrounding a Weirwood tree.
Then we saw it again in the latest episode, in the scene where Lord Umber woke up from the dead and terrified the living daylights out of people.
But what does this bizarre symbol mean? Is it like the Targaryen sigil? Is it just a shape that he likes? Well, Dave Hill, who wrote the episode, spoke to the New York Post about it and offered some clarity.
Hill said: "As we saw with Bran and the Three-Eyed Raven, the spiral pattern was sacred to the Children of the Forest, who created the Night King by sacrificing a captured man in a spiral 'henge of stones'.
"The Night King then adopted the symbol as a sort of blasphemy, like Satan with the upside-down cross."
Hmm. OK then.
If true, that means that all of the bizarre fan theories that are knocking around regarding this are wrong. However, it would seem a bit underwhelming if it turned out to mean nothing at all, wouldn't it?
After showing it to us on so many occasions, you'd have to believe that it means something, wouldn't you?
The second episode of the final season of Game of Thrones will air on Sky Atlantic on Monday 22 April at 2am, then again at 9pm that same day.
