9-1-1 promotes May and Harry Grant to series regulars for Season 9 as Athena leans on family after Bobby’s death
In a move signaling a stronger focus on family dynamics, Corinne Massiah and Elijah M. Cooper have been promoted to series regulars for the ninth season of ABC’s Los Angeles-set first-responder drama 9-1-1. Massiah, who portrays Athena Grant’s eldest daughter May, and Cooper, who plays Harry Grant, return to full-time status after periods of recurring or guest appearances.
Massiah has a long history with the series, starting as a recurring cast member in Season 1, becoming a regular from Seasons 2 through 5, then stepping back to guest and recurring stints as she pursued college. She recently graduated with a sociology degree from UCLA and will rejoin 9-1-1 as a full-time regular. Cooper has been a recurring presence since Season 7; the character was portrayed by a different actor in Seasons 1-5, and Harry missed Season 6 when he went to live with his father.
The Season 9 regular roster now includes Angela Bassett as Athena Grant, Jennifer Love Hewitt as Maddie Han, Oliver Stark as Evan “Buck” Buckley, Kenneth Choi as Howie “Chimney” Han, Aisha Hinds as Henrietta “Hen” Wilson, Ryan Guzman as Eddie Diaz and Gavin McHugh as Christopher Diaz, alongside Massiah and Cooper.
9-1-1, created by Ryan Murphy, Brad Falchuk and Tim Minear, follows first responders—police, firefighters and dispatchers—through high-pressure emergencies in Los Angeles. The show picked up momentum after Bobby’s shocking and heroic death in the closing episodes of Season 8, and Season 9 is set to premiere on October 9 on ABC, with subsequent availability on Hulu the following day.
The series is produced by 20th Television in association with Ryan Murphy Television and Brad Falchuk Teley-Vision, with Minear serving as showrunner. Executive producers include Bassett, John J. Gray, Brad Buecker and Kristen Reidel, among others.
Corinne Massiah has previously appeared in Secrets and Lies and Mistresses, among other projects, while Elijah M. Cooper has recent credits on Goosebumps and All American. Both actors are represented by major agencies, underscoring the network’s intent to anchor Season 9 around their characters.
What this means for Season 9
– May and Harry are positioned to play larger roles in the ongoing aftermath of Bobby’s death, enabling richer family-centered storytelling.
– Athena’s reliance on her children may drive new emotional arcs and decision points for the Grant family.
– The show continues to blend high-stakes rescues with intimate, character-driven moments, a hallmark that fans have come to expect.
Summary
Two key young players on 9-1-1 have moved to series regulars for Season 9, signaling a renewed emphasis on the Grant family as the series navigates the aftereffects of Bobby’s death. Massiah’s May returns to a full-time role, while Cooper’s Harry deepens his ties to the ensemble, set against the backdrop of Los Angeles’ first responders.
Positive note
This shift offers fans opportunities for hopeful, resilient storytelling as May and Harry grow into more central roles and as Athena leans on family strength to move forward.
