Fair warning, guys -- we're going to be talking SPOILERS for Game of Thrones through season 5 of the show, and all books. So like everything. You've been warned!


7. Jon Snow has a twin sister (and she's not a Stark)

If you've only read one fan theory about Game of Thrones, it's the popular (and probably accurate) tale known as R + L = J. In short, Ned Stark lied about fathering a bastard child with a random mistress; instead, Jon Snow is a result of a secret  tryst between Ned's sister Lyanna Stark and Daenerys' big bro Rhaegar Targaryen. You can spend an afternoon read up on all the evidence instead of doing what you actually wanted to do today, but at this point the "theory" is pretty much set in stone. It's one of the only things the entire internet can agree on, like puppy videos and the fact that those two dudes from Supernatural are totally into each other. 

Not long after the conspiracy was established as canon, we got another conspiracy on top of that. It's not enough that Jon Snow is the product of a forbidden love affair and maybe the savior of Westeros -- he might also have a twin sister

Hmm, why does "secret twins destined for greatness" sound familiar? Oh, right.

The Star Wars comparison might seem a bit on-the-nose, but that's exactly how Theon Greyjoy actor Alfie Allen described it. After asking George R.R. Martin about Jon Snow's true parentage, Allen spoke in vague terms about what he'd been told, specifically citing that it's "a bit of a Luke Skywalker situation." And we all know Luke ended up having a fraternal twin he never knew about.

So who's the mystery sister from the same mister? Meera Reed, who up to this point has been hanging out with Bran and Hodor in no one's favorite storyline.

Right off the bat, the two look a good deal alike, though that may say more about Jon's taste for high-end conditioner. Then there's the fact that we know that Jon and Meera are the same age, which is more than a little pivotal for a theory about twins. Then there's the matter of Meera's father. Howland Reed happens to be the only one besides Ned to survive the raid at the Tower of Joy, the place where Lyanna Stark died and presumably made her brother promise to take care of the newborn, Jon. If this really is a Luke and Leia twin situation, it would make sense for Howland and Ned to each take a child to raise as their own. Ned took Jon, and Howland ended up with Meera. 

One of the enduring prophecies of the World of Ice and Fire is that "The Dragon Has Three Heads," indicating that there are three heroes, probably Targaryens, with inexorably intertwined fates. If one is Daenerys and the other is Jon, who else do we have for the third head but Meera? She's just as valid an option as say, Tyrion or Sam. Really, we'll take anyone over Ramsay at this point.


6. Two dead brothers will come back to life and fight each other


One of the most popular fan theories out there is so widespread that in some circles, it's not even a theory -- it's a prophecy. Basically: Sandor "The Hound" Clegane and Gregor "The Mountain" Clegane will cross paths once more, resulting in a balls-out bro-brawl that will shake the heavens. Diehards have christened this world-cracking fantasy battle with the epic name CLEGANEBOWL.  

You can't blame fans for wanting a solid conclusion to this sibling rivalry. The last time we got to see the two square off was just for a minute or two in the first book. In the show, Gregor was even played by an entirely different actor. 

The only potential problem with this theory: The Hound and The Mountain are both dead. Well, kind of. Even though the director of the Hound's last televised episode was sure of his demise, there are some strong hints in the books that say Sandor still walks Westeros. In A Feast for Crows, Brienne runs afoul of a familiar gravedigger. 

On the upper slopes they saw three boys driving sheep, and higher still they passed a lichyard where a brother bigger than Brienne was struggling to dig a graveFrom the way he moved, it was plain to see that he was lame. As he flung a spadeful of the stony soil over one shoulder, some chanced to spatter against their feet. "Be more careful there," chided Brother Narbert. "Septon Meribald might have gotten a mouthful of dirt." The gravedigger lowered his head. When Dog went to sniff him he dropped his spade and scratched his ear."

"A novice," explained Narbert.

Remember, in the books Brienne never had that huge battle with the Hound, so she wouldn't know what he looked like. So what we've got here is a giant man with a limp, apparently new to digging graves, who also happens to be fond of dogs. If you think that sounds pretty Houndy, you're not alone.

As for Gregor, you don't have to go digging through the text to find him -- we've already seen the Mountain rise again on the show

The general consensus is that the giant golden knight that picks up Cersei at the end of her Walk of Shame is in fact the Mountain, or at least a warped version of him. If you remember, mad scientist Qyburn was working on some Frankensteiny experiments throughout the series, and zombie Gregor was the result.

So if both Clegane brothers are alive, they totally have to fight again, right? Maybe Cersei will call for a trial by combat and pitch in Zombie Mountain as her champion. And just maybe the faith will bring over their gravedigger to fight for them, and we'll have ourselves an epic rematch. Sounds impossibly rad, right? 

That's kind of the problem. It's too perfect. Seeing Cleganebowl to its completion would be way too satisfying for George R.R. Martin, the same guy who had Stannis march around Westeros for years to seemingly no end. Game of Thrones isn't known for giving fans what they want, much less what they crave. But we can still hold out hope. And if Cleganebowl ever occurs, you're gonna wanna be in the front row. Maybe bring one of those plastic ponchos -- it's gonna get messy.
