The buzz surrounding A Knight of the Seven Kingdoms has reached fever pitch. As HBO’s latest expansion into the world of Westeros premiered in January 2026, introducing audiences to the humble hedge knight Ser Duncan the Tall (Peter Claffey) and his enigmatic squire Egg (Dexter Sol Ansell), fans quickly realized this wasn’t just another tale of dragons and thrones. It’s a grounded, character-driven story set roughly 90 years before the events of Game of Thrones, drawing from George R.R. Martin’s Tales of Dunk and Egg novellas. Yet amid the tourneys, border skirmishes, and budding brotherhood between Dunk and Egg, a deeper emotional thread is emergingāone that could quietly bridge this prequel back to the original series in the most poignant way imaginable.

The character in question? Maester Aemon Targaryen, the wise, blind maester of Castle Black who served as a mentor to Jon Snow and delivered some of Game of Thrones‘ most heartbreaking lines. For longtime viewers, Aemon’s name evokes quiet dignity amid chaos: the man who forsook a crown for duty, who advised against ambition’s pitfalls, and whose final wordsā”Egg, I dreamed I was old”āstill linger like a ghost. Now, with whispers from the show’s showrunner and subtle nods already appearing on screen, speculation is rampant that a younger version of Aemon could appear in the series, perhaps as early as the already-in-production Season 2. If it happens, it wouldn’t be a flashy cameo but something far more powerful: a living link to the sacrifices that shaped Westeros’ history and a reminder of the brotherhood that defined both Egg’s youth and Aemon’s life.
The Timeline: Where Aemon Fits in the Dunk and Egg Era
To understand why Aemon’s potential return feels so tantalizing, we must map the chronology. A Knight of the Seven Kingdoms Season 1 adapts The Hedge Knight, set in 209 AC during the reign of Daeron II Targaryen (known as “the Good”). Here, Prince Maekar Targaryen (Sam Spruell) is a stern, ambitious royal whose sons are already causing ripples in the realm. Maekar’s four boys include Daeron (the eldest, often absent and rumored to be unreliable), Aerion (the volatile “Brightflame,” played by Finn Bennett), the third sonāAemonāand the youngest, Aegon, who runs away to squire for Dunk under the name “Egg.”
By the time of The Hedge Knight, Aemon has already been sent to the Citadel in Oldtown to train as a maester. This decision stemmed from King Daeron II’s concern over too many Targaryen heirs potentially sparking succession crisesāironic, given the family’s history. Aemon, bookish and scholarly from a young age, accepted this path without protest. He was around 11 years old during the events of The Hedge Knight, and though he doesn’t appear directly in Martin’s novella, he’s referenced indirectly: characters gossip about one of Maekar’s sons being “useless” enough to be shipped off to become a maester.
In the show, this Easter egg has already surfaced. In one early episode, a character dismisses the third Targaryen brother with a cutting remark about his impending life at the Citadel. For book readers, the implication is clear: this is Aemon, the overlooked prince whose quiet life would later intersect with the Wall’s grim duties.
The real emotional hook comes later. Between The Hedge Knight and The Sworn Sword (the basis for Season 2), Dunk and Egg visit Oldtown during or after the Great Spring Sickness. There, they meet Aemon, who measures Dunk’s towering height for curiosity’s sake and gifts his little brother a mule named “Maester.” This brief encounter underscores the genuine affection between the brothersāAemon, the studious older sibling who nicknamed Egg in their childhood games of mock battles and dragon dreams, and Egg, the impulsive runaway who idolizes knighthood over crowns.

The Showrunner’s Tease: “Possible. Almost Happened. Then It Didn’t. Maybe⦔
The speculation ignited when showrunner Ira Parker addressed the question head-on during a Reddit AMA. Asked if Aemon might appear, Parker replied cryptically: “Possible. Almost happened. Then it didn’t. Maybe⦔ The phrasing is classic HBO ambiguityāenough to fuel forums and fan theories without committing outright. Reports indicate a version of the character was considered for Season 1 but ultimately cut, perhaps to preserve fidelity to the source material or to build anticipation.
This isn’t unprecedented. A Knight of the Seven Kingdoms has stayed remarkably loyal to Martin’s novellas so far, focusing on Dunk’s outsider perspective rather than deep Targaryen intrigue. Aemon doesn’t physically appear in any of the three published stories (The Hedge Knight, The Sworn Sword, The Mystery Knight), but mentions accumulate, especially as Egg’s royal identity unfolds. Introducing him would require a minor deviationāperhaps expanding that Oldtown visit into a full sceneābut the payoff could be immense.
Imagine it: a young Aemon, perhaps 13 or 14 by Season 2’s timeline, greeting his runaway brother with a mix of relief and gentle scolding. Egg, still bald-headed and defiant, might share tales of hedge-knight adventures, while Aemon offers quiet wisdom about duty and sacrifice. For viewers who remember Peter Vaughan’s portrayal of the elderly maesterāfrail yet sharp-minded, reciting Night’s Watch history with reverenceāthe contrast would hit hard. Here is the boy who will one day stand at the Wall, forgoing kingship so his little brother can rule as Aegon V “the Unlikely.” Here is the man who will counsel Jon Snow against rash decisions, drawing from a lifetime of choosing peace over power.
Why Aemon’s Return Would Reshape Our View of Sacrifice
Aemon’s arc is one of Game of Thrones‘ most understated tragedies. As the third son, he was never expected to rule, but fate intervened. After Daeron dies mysteriously and Aerion perishes in a grotesque wildfire experiment, Aemon becomes heir presumptive. Yet he refuses the Iron Throne, citing his maester’s vows. To further remove himself as a pawn in future plots, he joins the Night’s Watchāensuring no one can use his Targaryen blood against Egg’s reign.
This sacrifice echoes through the original series. When Aemon learns of the realm’s turmoil via raven messages, he remains at the Wall, loyal to his oaths. His bond with Jon Snowāanother reluctant leader who grapples with heritageāfeels even more layered knowing Jon is unknowingly related (Aemon is Jon’s great-great-uncle). And that final scene in Season 5, where the dying Aemon whispers “Egg, I dreamed I was old,” becomes devastatingly literal in this context: in his delirium, he imagines reuniting with his brother, the boy he once nicknamed and protected.
Seeing young Aemon interact with Egg would reframe everything. The “brotherhood” Dunk and Egg buildāforged in hardship, loyalty, and mutual growthāmirrors the Targaryen sibling bond that Aemon sacrifices for the greater good. It humanizes the Targaryens beyond fire and blood, showing a family capable of love, restraint, and quiet heroism. In a franchise often criticized for cynicism, Aemon represents enduring decency: the prince who chose learning over lordship, duty over dominion.
The Bigger Picture: Bridging Eras in Westeros
HBO’s strategy with A Knight of the Seven Kingdoms emphasizes accessibilityāno dragons, fewer politics, more heart. Yet tying it to Game of Thrones via Aemon would create the strongest emotional bridge yet. Unlike House of the Dragon‘s direct prequel ties, this would be subtle, character-focused, rewarding longtime fans without alienating newcomers.
Season 2, adapting The Sworn Sword and already in production for a 2027 release, offers the perfect window. The story shifts to border tensions and old grudges, but expanding the brothers’ reunion could add depth without derailing the plot. If Parker follows through on his “maybe,” it could elevate the series from charming side story to essential chapter in the Targaryen saga.
For now, the clues are tantalizing: on-screen references, showrunner teases, and the undeniable timeline fit. Aemon’s return wouldn’t involve battles or betrayalsājust a quiet moment between brothers that reminds us why some choices echo across generations.
In the end, if Aemon does step into the light of A Knight of the Seven Kingdoms, it won’t be as a king or conqueror. It will be as a boy who measured a giant’s height, gifted a mule, and one day dreamed of youth while facing the end. And for fans who watched him fade at Castle Black, that would be the most powerful return of all.
