John Stewart Sr. in ‘Lanterns’ Explained: Meet J. Alphonse Nicholson as John Stewart’s Father

HBO’s ‘Lanterns‘ has given comic fans something they never expected, a deep dive into the tortured family history behind Earth’s second Green Lantern. J. Alphonse Nicholson plays John Stewart Sr., the father of the show’s hero, who is a military man struggling with a legacy he never chose. His performance in episode three quickly became one of the most talked about elements of the season.

The episode, titled ‘OutKast’, reframes everything fans thought they knew about how John Stewart became a Lantern. Instead of a hero born fearless, viewers learn Abin Sur’s ring actually found John Stewart Sr. first, wrapping him in a green bubble and asking if he was afraid. That single question changes the entire trajectory of the Stewart family, and Nicholson is at the center of it.

J. Alphonse Nicholson’s Role as John Stewart’s Father

John is still an infant asleep in his crib when a green light sweeps over the family’s house, terrifying his father. Since Lanterns are expected to be fearless, that reaction gets him passed over for the ring entirely. The failure haunts John Sr. so deeply that he spirals afterward, at one point shooting the family television during a news segment about the Green Lantern.

Despite once serving as a Marine, John Sr. can’t shake the shame of failing the test, and people around him start to believe he’s lost his mind. His own wife eventually demands he leave the house for a while, a moment that reshapes how the family functions from that point forward.

‘Lanterns’ does not romanticize this backstory either. The show frames John’s childhood as one shaped by real abuse stemming from his parents’ own unresolved trauma. It’s a bold choice for a superhero origin story, and it gives Nicholson’s performance a weight rarely seen in comic book adaptations.

John Stewart Sr.’s Green Lantern Ring Test

The ring test itself is the emotional core of the episode. When the ring asked John Sr. if he was afraid, he shouted yes, and it moved on without him. That single word defines the rest of his arc.

Nicholson has spoken publicly about how meaningful that moment is within the larger context of the show. He told TheWrap he was grateful the writers included that beat, questioning how any Black man in America could reasonably be expected to move through the world fearless. It’s a rare instance where a genre show uses its premise to comment directly on real world experience.

John Sr. was passed over by the Guardians, and that rejection becomes the wound his entire family is built around trying to heal.

Bernadette and John Sr.’s Plan For Their Son

After the failed test, Bernadette, played by Jasmine Cephas Jones, and John Sr. begin training their youngest son to become fearless from infancy, essentially building him into a Green Lantern candidate the way elite athletes are raised by ambitious sports parents. The show even draws comparisons to how the families of Tiger Woods, Serena Williams, and Stephen Curry shaped their children’s futures.

On John’s fifth birthday, his parents sit him down and explain his destiny, telling him he’ll be schooled separately from other kids. They even tell him the birds around the house are watching over the family and reporting back to the Guardians.

The pair eventually gift young John a Lantern costume and a gun, and it becomes his own idea to place an apple on his head so his father can shoot it off in the backyard. That scene directly explains the shocking William Tell style moment fans saw earlier in the season’s pilot episode.

Bernadette explains to the Guardian, played by Laura Linney, just how unfair it is to ask a Black man in America whether he is afraid, given the daily reality of persecution he lives with. It’s a line that reframes the entire premise of fearlessness the Lantern Corps demands of its members.

Nicholson’s Approach to Playing John Stewart Sr.

Nicholson, known for his work on ‘P-Valley’, has spoken candidly about drawing from his own life to build the character. He said he starts from his own experience as a father, admitting he knows what it feels like to be a flawed parent and to feel like a failure.

Nicholson also revealed that once he read the script, he immediately sensed it had been written by a Black woman, saying she clearly knew him and understood who he was. That writer turned out to be Vanessa Baden Kelly, who penned the pivotal episode.

Interestingly, Sherman Augustus takes over the role to portray an older version of John Sr. later in the series, meaning Nicholson’s version represents the character during the most formative and painful chapter of his life.

What Comes Next For John Stewart Sr.?

The response to episode three has been massive, and Nicholson is already hoping for more. Speaking with ScreenRant, he pointed to the episode’s massive audience numbers as reason enough for a second season, and said he would love to explore John Sr.’s redemption story further, including how the relationship with a teenage John might evolve.

He also raised a question that lingers over the rest of the season, wondering aloud how John Sr. could ever have a real conversation with Hal Jordan again after being passed over for the ring twice in his family’s history. Whether the show answers that in a potential season two remains to be seen.

For now, John Stewart Sr. stands as one of the most quietly devastating characters in ‘Lanterns’, a man whose single moment of honesty changed the course of his entire family. What do you think John Sr. deserves most in a potential season two, a real reckoning with Hal Jordan, or a chance to finally make peace with the son he pushed so hard to become a hero.
