Joining the medical drama in Season 6 as part of the Mercy West merger, Jackson evolved from a competitive surgical resident into the principled, compassionate Chairman of the Grey Sloan Memorial Board.
To celebrate Williams’ birthday, we are looking back at the definitive Grey’s Anatomy episodes that proved he was far more than “just the pretty one”.
1. “Sanctuary” and “Death and All His Friends” (Season 6, Episodes 23 and 24)
Jackson’s breakout moment arrived during one of the most intense, heart-stopping finales in television history. When a gunman terrorizes Seattle Grace Mercy West, Jackson steps up under extreme duress.
Operating on a critically wounded Derek Shepherd while held at gunpoint, Jackson executes a brilliant, split-second trick: disconnecting the heart monitor to fake Derek’s death so the shooter leaves the operating room. Williams delivered a masterclass in quiet bravery, proving in his very first season that Jackson possessed true heroic instincts under pressure.
2. “Get Up, Stand Up” (Season 10, Episode 12)
No list of Jackson Avery highlights is complete without the most infamous wedding objection in primetime TV. As April Kepner stands at the altar about to marry paramedic Matthew, Mark Sloan’s past advice rings in Jackson’s ears: “If you love someone, you tell them.”
Jackson stands up mid-ceremony and stuns the congregation by confessing his love to April in front of everyone. Williams balanced vulnerability and sheer impulse, cementing the fan-favorite “Japril” dynamic into the pop-culture hall of fame.
3. “Transplant Wasteland” (Season 9, Episode 17)
Following the devastating plane crash that claimed the lives of Mark Sloan and Lexie Grey, the hospital faces bankruptcy. When the Harper Avery Foundation steps in to buy the facility, Jackson is thrust into the role of Board Chairman over his seasoned mentors.
Overcoming self-doubt and pushback from senior attendings, Jackson makes his first authoritative power move: proposing that the hospital be officially renamed Grey Sloan Memorial Hospital. It marked a monumental turning point where Jackson stepped out from his family’s shadow to become a true leader.
4. “Unbreak My Heart” (Season 12, Episode 11)
Entirely dedicated to Jackson and April’s turbulent love story, this standalone episode travels backward and forward through time—tracing their trajectory from divorce papers all the way back to their early days at Mercy West.
Williams delivered some of his rawest dramatic work on the series, capturing the profound grief of losing their infant son, Samuel, alongside the lingering tenderness that kept drawing the couple back together.
5. “Look Up Child” (Season 17, Episode 14)
Serving as Williams’ departure episode as a series regular, Jackson embarks on a soul-searching road trip to visit his estranged father and later reconnect with April. Realizing that his true calling is to fight systemic racial inequities in medicine, Jackson decides to take control of the Catherine Fox Foundation and move to Boston. Williams brought incredible emotional depth to his farewell, offering fans a deeply satisfying conclusion that paved the way for Jackson and April’s eventual reunion.
