When House of the Dragon decided to swap out Nettles—a key dragonrider from George R.R. Martin's Fire and Blood—for Rhaena Targaryen (Phoebe Campbell), it sparked plenty of debate. On one hand, the shift streamlines a crowded cast and gives Rhaena a much bigger role. On the other, it erases one of the few canonically Black women in Martin's world, and Nettles' mysterious parentage challenged the Targaryen obsession with pure bloodlines. Love it or hate it, the change is locked in, and as Season 3 hits its midpoint, the dramatic fallout is hitting hard.
A Father's Long-Awaited Moment
Daemon Targaryen (Matt Smith) has never exactly been Father of the Year. His relationships with his daughters Baela and Rhaena have mostly played out offscreen or been implied at best. A deleted scene from Season 1 showed him embracing them after Laena's death, but he was too lost in his own grief to truly comfort them. That pattern of non-malicious negligence makes his discovery of Rhaena and the wild dragon Sheepstealer in the Vale all the more powerful. It's a belated chance to explore a side of Daemon we've rarely seen: a father trying—and failing—to do right by his child.
Smith and Campbell deliver gut-wrenching performances. Smith, in particular, shows a Daemon we've never seen before: defeated, devastated, oscillating between shock, tenderness, and paternal frustration. These are rich, underutilized character shades that the series is finally tapping into.
Daemon's Deception Could Backfire
Episode 4 sets up a deeply emotional conflict. Rhaena, still reeling from Jacaerys' murder, assumes her stepmother Rhaenyra would harm her—a leap, given Rhaenyra's reluctance to execute even Otto Hightower. But Rhaena is a teenager who has always felt like the family's failed outcast, echoing Daemon's own fraught relationship with his brother Viserys. She acts recklessly, but her disobedience doesn't deserve self-exile. Daemon, fresh off taking accountability for his flaws and pledging himself to Rhaenyra, is now forced to choose between betraying his daughter's desperate plea or betraying his queen.
As most parents would, he chooses his frightened daughter. But his cornered panic leads him to default to impulsive violence and a flimsy lie. For the first time, we see Daemon step into his parental responsibility—flawed but sincere—just as he and Rhaenyra have reached their healthiest solidarity. The result is a ticking time bomb that could shatter their marriage.
A Tragedy in the Making
If we judge this controversial deviation on its own merits, it's a staggering complication with enormous character-driven potential. This Daemon wouldn't stray from his loyalties for a stranger; he would tear himself apart for the family he vowed to protect. The inevitable aftermath is a grieving family fragmenting when they need each other most.
