Jasmine Cephas Jones plays Bernadette, Jon Stewart’s mother, in HBO Max’s Lanterns
The actress stepping in as John Stewart’s mom Bernadette on HBO’s Lanterns may not be who you expect — and her career’s worth a look.
The episode’s gut-punch arrives in a tense home scene where Bernadette Stewart all but drills fear out of her young son. Played by Jasmine Cephas Jones, Bernadette runs John through hard lessons meant to steel him long before a power ring ever finds him. Within minutes she’s tender, severe, terrified and unflinchingly resolute — the person who decides courage isn’t a gift, it ’s training.
Episode 3 also fills in how that training began: after a Guardian informs the Stewarts that John has qualities tied to the Green Lantern Corps, Bernadette becomes the architect of his childhood regimen. The character is described as a resilient family fixer who holds herself — and everyone around her — to a punishing standard. Here, that ideal shapes John’s origin in ways that feel both protective and haunting.
Meet Jasmine Cephas Jones
Cephas Jones broke out in Broadway’s Hamilton, where she originated the dual roles of Peggy Schuyler and Maria Reynolds and earned a Grammy as part of the cast album. Since then she’s split her time across film and TV, often jumping genres without blinking.
- Blindspotting — Ashley (and later a producer on the Starz series)
- #FreeRayshawn — Tyisha (Primetime Emmy winner)
- Monsters and Men — film
- The Photograph — film
- Marriage Story — film
- Origin (Ava DuVernay) — film
- Mrs. Fletcher — TV series appearance
That range pays off in Lanterns, where she plays Young Bernadette with a mix of warmth and rigor that makes John’s upbringing feel deliberate rather than accidental. The episode effectively positions her as the emotional backbone of his backstory.
Sinestro’s shadow
Episode 3 also widens the cosmic lens around Sinestro, played by Ulrich Thomsen. It confirms he once trained Hal Jordan, with a bond built on trust before his fall from grace — a fall that included killing a Guardian during an attempted coup and landing in an intergalactic prison.
Episode 3 confirms Sinestro once trained Hal Jordan — and that he killed a Guardian before being imprisoned.
That history isn’t academic for Hal. Earlier this season, he visited Sinestro behind bars looking for answers about the Manhunters, a choice the Guardians eye warily as his old loyalties keep showing. Even John Stewart notes how people can stay attached to the figures who raised and shaped them, even when those figures cross unforgivable lines.
All of it plays against a looming question: the season began with Hal’s apparent death, and Episode 3 layers in fresh tension among Hal’s allies, the Guardians and John while making Sinestro’s influence impossible to ignore. Who killed Hal — and why — remains unresolved.
