Why Is Hershel Becoming a Doctor in Dead City Season 3? His Grandfather’s Legacy Explained

Hershel Rhee has spent most of The Walking Dead: Dead City struggling to decide who he wants to become. Season 3 finally gives him an answer that has surprisingly little to do with Maggie, Negan or the Dama.

Hershel wants to become a doctor, and the choice is deliberately meant to continue the legacy of his grandfather, Hershel Greene. Newcomer Luis is training him in medicine, while showrunner Seth Hoffman has explicitly confirmed that Hershel realizes he wants to follow in his grandfather’s footsteps. Episodes 2 and 3 turn that idea into an actual storyline, showing Hershel studying anatomy and helping treat injured survivors.

For a character who never had the chance to meet the man he was named after, it is one of Season 3’s most meaningful connections to the original Walking Dead.

Why is Hershel studying medicine in Dead City Season 3?

Hershel’s medical training begins through Luis, the doctor played by Raúl Castillo.

Luis arrives in Season 3 alongside his sister Renata and quickly becomes essential to the new community developing in Manhattan. In a world where trained doctors are increasingly rare, his knowledge is as valuable as food, weapons or electricity. Hershel begins spending time with him and discovers a role that seems to fit him better than the political ideas and power struggles that consumed him during Season 2.

Episode 2 makes the change impossible to miss. Hershel studies anatomy using a severed walker arm, manipulating tendons to understand how the hand works. It is a gruesome version of medical homework, but in the world he lives in, it makes perfect sense.

By Episode 3, the training has already moved beyond theory.

When Manhattan receives an unexpected influx of injured survivors, Luis cannot handle every patient by himself. Hershel helps in the hospital and is forced to work under pressure as wounded people die and reanimate around him.

This is no longer simply a teenager looking for something interesting to do. Season 3 is establishing medicine as Hershel’s emerging purpose.

Is Hershel becoming a doctor because of Hershel Greene?

Yes. That connection has been confirmed by the show’s creative team.

Before Season 3 premiered, showrunner Seth Hoffman explained that Hershel’s relationship with Luis would lead him toward medicine and specifically described the choice as Hershel following in his grandfather’s footsteps.

That grandfather, of course, is Hershel Greene, Maggie’s father and one of the most important early survivors in The Walking Dead.

Hershel Greene was technically a veterinarian rather than a human physician before the apocalypse, but the distinction became far less important once civilization collapsed. His medical knowledge repeatedly made him the group’s doctor when no better option was available.

He famously saves Carl Grimes after Carl is accidentally shot near the Greene farm. Later, after the survivors establish themselves at the prison, Hershel becomes one of the community’s most dependable medical figures. During the deadly illness that spreads through the prison population, he willingly enters the quarantined cell block to care for the sick despite knowing how easily he could become infected himself.

Medicine was therefore only part of what made Hershel important.

He represented compassion, patience and the belief that protecting life still mattered even when the world constantly provided reasons to abandon those values.

Season 3 appears interested in passing some of that philosophy to his grandson.

Did Hershel Rhee ever meet his grandfather?

No. Hershel Greene died years before Hershel Rhee was born. The Governor murders him during the attack on the prison in The Walking Dead Season 4, long before Maggie becomes pregnant with Glenn’s child.

Maggie later names her son Hershel in honor of her father.

That makes the Season 3 storyline particularly interesting because Hershel Jr. is not consciously copying someone who personally taught him. Whatever he knows about his grandfather would have come through Maggie and the surviving stories of the people who knew him.

There is also an obvious difference between the two Hershels.

The elder Hershel entered the apocalypse as an experienced adult with an established profession and strong moral convictions. His grandson has never known a normal world. Violence, walkers and unstable communities are ordinary parts of his life.

For Hershel Jr., becoming a healer would therefore mean deliberately choosing to preserve life in the only world he has ever understood.

That gives the decision considerably more weight than simply giving him his grandfather’s old occupation.

What does Luis mean for Hershel’s future?

Luis provides something Hershel has been missing for much of Dead City: a mentor whose relationship with him is not built around manipulation or family conflict.

The Dama also recognized Hershel’s intelligence and ambition, but she exploited his resentment toward Maggie and encouraged his belief that ruthless control was necessary to rebuild civilization. Hershel became vulnerable to her influence partly because she made him feel listened to.

Luis offers a very different path.

Instead of telling Hershel how the world should be controlled, he teaches him a practical skill that can make him useful to other people. The relationship gives Hershel responsibility without requiring him to become another political leader or fighter.

Actor Logan Kim has also described Hershel’s Season 3 journey as learning from Luis and taking the steps toward becoming a doctor.

That does not mean Hershel is suddenly a fully trained physician. Traditional medical education barely exists in this world, and a few months of apprenticeship cannot replace years of training.

What the show is depicting is something closer to the way medicine often operated earlier in The Walking Dead: knowledge being passed from the experienced to whoever is willing and capable enough to learn.

Is Hershel being set up to find a cure for the walker virus?

There is currently no evidence of that.

Hershel’s interest in medicine has naturally encouraged theories that Dead City could eventually connect him to larger scientific mysteries in the franchise, including research into the walker infection. But Season 3 has not established that he is studying virology, searching for a cure or working with any organization such as the CRM.

His training is far more immediate.

He is learning anatomy, helping injured survivors and developing the skills necessary to keep ordinary people alive. That is already a significant role in a civilization trying to rebuild itself.

Anything involving a cure remains speculation.

The more grounded interpretation is also the stronger one: Hershel has finally found a way to define himself without being reduced to Maggie’s son, Glenn’s son or the young man the Dama tried to shape.

Hershel’s new purpose completes a Greene family circle

Season 3’s medical storyline lands especially well because Hershel Rhee has spent so much of Dead City separated from the family history represented by his name.

He never met his father. He never met his grandfather. His relationship with Maggie has been damaged by years of trauma and her inability to completely escape what Negan did to Glenn.

Yet Hershel is now beginning to carry pieces of those people forward anyway.

Maggie has already entrusted him with the Greene family’s pocket watch, an object that once passed from Hershel Greene to Glenn. Medicine gives him a second connection to the grandfather whose name he inherited.

The difference is that this one is not simply an heirloom.

It is something Hershel has chosen for himself.
