With the “Game of Thrones” Season 6 finale, the internet's speculation machine has kicked into overdrive with incredible theories on what will happen next in Westeros. Some are nothing more than lighthearted banter on Reddit, but there's speculation grounded in leaks and evidence from the show. If anything, the speculation for the finale is just a warmup for months of “Game of Thrones” Season 7 theories.

Warning: Full “Game of Thrones” Season 6 spoilers ahead. Some discussion is based on potential leaks from Reddit, so proceed with caution.

Mad Queen Theory

Cersei Lannister seems to be spiraling out of control, which is why the whole “Mad Queen” theory makes a bit of sense. Before the beginning of “Game of Thrones,” the Mad King’s descent into insanity led to his grand plan of burning King’s Landing to the ground using hidden stores of wildfire placed at strategic locations.

The stores of wildfire were used by Tyrion Lannister to defend King’s Landing in “Game of Thrones” Season 2, episode 9, “Blackwater.” Tyrion discovers Cersei is amassing a large amount of wildfire from the remaining pyromancers in King’s Landing. The wildfire is being created in preparation for an attack against Stannis Baratheon. Tyrion takes over the production of wildfire, which he then uses in the Battle of Blackwater. Instead of attacking Stannis’ fleet of ships, Tyrion sends a ship loaded with wildfire into the middle of battle. A flaming arrow from Bronn leads to a massive explosion that destroys Stannis’ ships.

Considering Cersei’s previous appreciation for wildfire and the Mad King’s stockpile in King’s Landing, it makes sense for her to revisit this plan to address the threat of the High Sparrow and the Faith Militant. Cersei is cornered after losing control of King Tommen to the High Sparrow, Jaime’s departure to Riverrun and trial by combat being banned.

The seeds for the wildfire plan were sowed in “Game of Thrones” Season 6, episode 8. Qyburn used Varys’ spy network of children to investigate something within the city. It turns out what Qyburn found was way bigger than some old rumor. No specifics are given, but many viewers believe Cersei and Qyburn were discussing the rumor of the Mad King’s store of wildfire in King’s Landing.

Cersei could be planning to destroy the Great Sept of Baelor with wildfire, but that plan could easily go awry. Tyrion’s big fear over using wildfire was its unpredictable nature, but Cersei does not have the same foresight as her brother.

Wildfire could take over the Great Sept but soon spread unchecked through the city. That could lead to some startling deaths. There’s one rumor that Tommen could be trapped in a burning room where his only option is to leap out a window. Unfortunately, he does not survive, which would fulfill the Maggy the Frog’s prophecy, which stated Cersei would outlive her children.

Taking the parallel to the Mad King one step further, Jaime could arrive to find King’s Landing ablaze. Jaime would have a tough choice to either let Cersei live or kill her to stop the chaos. That dilemma would likely be saved for “Game of Thrones” Season 7, based on contract negotiations. The Hound getting revenge by killing his brother, the Mountain, will also have to wait until next season.

Tower of Joy (R+L = J)

While the Mad Queen theory is more speculative, it’s almost guaranteed the “Game of Thrones” Season 6 finale will revisit the Tower of Joy scene from earlier in the season. Bran Stark and the three-eyed raven warged back in time to witness the famous fight between Ned Stark and Ser Arthur Dayne, better known as the Sword of the Morning. Dayne was arguably the greatest swordsman to have ever lived, so it was pretty impressive to know Ned bested him in combat.

What actually happened was far less noble than the tale told to Bran. Ser Arthur Dayne completely decimates Ned’s forces leading to a one-on-one battle. Ned is on the losing end, but an injured Howland Reed manages to stab the Sword of the Morning from behind. It was not really honorable, but it was effective.

The flashback ends with a cry coming from the tower. Ned runs to find his sister, Lyanna Stark, but stops as though he heard something. The three-eyed-raven ends the session, but there were so many answers to be found within that tower. Most important, that one scene with Ned and Lyanna could confirm the “R+L = J” theory.

It would be fitting for the “Game of Thrones” Season 6 finale to reveal the secret that went to the grave with Ned Stark. If R+L = J is to be believed, Jon Snow is the son of Rhaegar Targaryen and Lyanna Stark. That would give him a legitimate claim to rule the North along with a lineage that could affect the future of Westeros.

With the fallout of the “Battle of the Bastards” featured in previews for “Winds of Winter,” a Tower of Joy scene could legitimize Jon Snow as the new King of the North. It’s unclear if Jon also discovers his parentage or if the reveal will be limited to Bran and the viewers at home.

Sansa Is Pregnant

Rumors are flying of a potential Ramsay Bolton offspring based on comments made by Sansa Stark. Sansa has not explicitly said she was pregnant, but she did say, “I can still feel what he did in my body.”

Ramsay’s dying words that he’s a part of her could help bolster the Sansa pregnancy theory, but it seems pretty unlikely. “Game of Thrones” does a good job of providing some precedent to future events, but there have been no outward signs of a Sansa pregnancy. Sansa’s last words to Ramsay — that his name, house and memory will disappear — is another blow to the baby Ramsay theory.

Also supporting the theory’s detractors are the comments made by Liam Cunningham (Ser Davos Seaworth). “Unless he’s got one of those ‘Game of Thrones’ pregnancy sticks, he’s not going to know,” said Cunningham in an interview with the Huffington Post.

Luckily, fans will only have to wait a few more days to find out if their favorite theories are proved right during the “Game of Thrones” Season 6 finale.
