This post contains spoilers for the season seven finale of Game of Thrones.

It took seven seasons, 67 episodes, and Bran turning into an omniscient bird-tree, but Game of Thrones has finally confirmed the show's longest-standing theory: Rhaegar Targaryen and Lyanna Stark are Jon Snow's parents, and his real name is Aegon Targaryen. While the name Aegon wasn't a given, it's a very important clue about who Jon's parents expected him to become, especially since at the time of Jon/Aegon's birth, Rhaegar already had a son named Aegon with with his first wife, Elia Martell.

No really: Rhaegar's two existing children, who were made bastards when he annulled his marriage to their mother, were named Aegon and Rhaenys. They didn't survive Robert's Rebellion (the Mountain killed them along with their mother), but they were definitely alive when Rhaegar decided to name his new heir Aegon. The whole situation is either a massive dick move on Rhaegar's part or evidence that he knew the name was significant — in the history of Westeros, Aegons tend to do great and terrible deeds, so Jon/Aegon's parents were probably expecting their son to accomplish some important things.

The question is, which things? The previous Aegons have historically been all over the place, from being some of the greatest kings in history to the worst king in living memory (yes, worse than the Mad King). Does Jon/Aegon take after any of these Aegons past?

THE HISTORY OF AEGONS

1. Aegon the Conquerer

The first important Aegon in Westeros was Aegon the Conqueror, who conquered the seven Kingdoms with his two wives (who were also his sisters) and three dragons. He was the last person in Westeros to "break the wheel," since he united the frequently-warring Seven Kingdoms under the rule of a single royal house and established the still-present absolute monarchy.

I'm not saying it will absolutely happen this way, but if Daenerys is serious about breaking the wheel again, she could do worse than incestuously marry an Aegon Targaryen. If the two of them ever ride out on the dragons together, the entire continent of Westeros will experience a group flash of déjà vu. There's a little poetry in the possibility of another Aegon destroying the monarchy his ancestor and namesake created, don't you think?

2. Aegon the Usurper

The second Aegon was called "The Usurper" because he sought to take the throne from his older sister Rhaenyra. Even though Rhaenyra had been designated as her father's heir and was promised as the first female ruler of the Seven Kingdoms, Aegon II went to war and won, taking his sister's throne and continuing a line of exclusively male rulers. After he died, Rhaenyra's son became king after him anyway so HA!

An older, female Targaryen who intended to be queen but was undercut by a younger relative whose claim to the throne is based on the assumption that only men should inherit the kingdom? Yikes. Let's hope this Aegon is just a coincidence, for Daenerys's sake. Also, the deposed Queen Rhaenyra in that story fell in love with and married her uncle. That's...familiar.

3. Aegon the Dragonbane

The third Aegon was Aegon "The Dragonbane." The very last dragon in Westeros died when he was on the throne, which contributed to the decline of House Targaryen in power and status. He hated dragons because he saw one eat his mom, so there are some that say he purposefully neglected the last dragons to eradicate their kind for good. Joke's on him.

While there have been some theories that Daenerys's dragons won't survive the great war, making Jon/Aegon a symbolic Dragonbane, it's more likely that this wasn't quite the Aegon that Rhaegar had in mind when he was naming his sons. However, it was Lyanna's doomed relationship with a "dragon" that led to her death so dragons did kind of kill Jon's mom. If you squint really hard.

4. Aegon the Unworthy

The next Aegon, "The Unworthy," was the WORST. KING. EVER. He disliked his heir so much that he gave the Targaryens's ancestral Valyrian steel sword to one of his bastards instead of to the prince, which sparked a civil war that devastated the country and changed the politics of their house for the next 90 years. He very likely killed his own father. He was a corrupt, greedy, jerk who literally rotted alive and the maesters didn't help him because they saw him physically decaying where he laid and said, "This is probably divine punishment for being an awful person and we shouldn't mess with that."

...let's just move on to the last Aegon.

This is just to say the bar for totally effing this up is pretty high for Jon/Aegon.

5. Aegon the Unlikely

Don't worry, the fifth and last Aegon was much better than the past few. He was called Aegon "The Unlikely" because he inherited the throne after a series of tragedies knocked out the nine people ahead of him in line, and after his older brother Aemon declined the crown since he was a maester (yep, that's the Maester Aemon from the show). He spent his childhood traveling disguised as a peasant and was a friend to the common people of Westeros. In order to force the lords of Westeros to accept reforms that benefited peasants instead of nobles, he attempted to hatch a dragon egg and died in the resulting fire. This fire caused the Tragedy of Summerhall, during which Rhaegar Targaryen was born and Aerys "The Mad King" ascended to the throne.

Jon's upbringing as a bastard and his genuine concern for human life makes him a lot like Aegon the Unlikely. He's fought alongside peasants and wildlings, and would probably do anything to protect Westeros from being lorded over by an unscrupulous queen (or turned into a bunch of ice zombies). He would certainly be an unlikely ruler not because his claim isn't direct, but because he's been lied to about his identity for his entire life and Jon/Aegon taking the throne would be the most out-of-left-field–ass move in the history of Westeros.

We'll have to wait a while to see how Jon reacts to learning he's Aegon Targaryen, but the importance of the name won't be lost on him, Daenerys, or any of the other players in the game of thrones. Every time an Aegon shows up on the scene, something massive happens, and nobody has any idea if that's a good or a bad thing yet. It's totally possible that finding out he banged his aunt will be the least of Aegon "The Unsuspecting's" concerns.
