As if its dramatic COVID-19 storylines weren’t enough, the medical drama also bid farewell to three series regulars during Season 17. The first, Andrew DeLuca (Giacomo Gianniotti) was shockingly murdered midway through the season while attempting to chase down a child trafficker. The second, Jackson Avery (Jesse Williams) bid farewell to Grey Sloan Memorial Hospital on his own terms, resigning from his position as Chief of Plastic Surgery at the Seattle hospital in order to travel to Boston and head up his family’s multi-million dollar foundation, with his ex-wife April (Sarah Drew) and their daughter Harriet in tow. There, Jackson hoped to revolutionize the world of modern medicine, bringing affordable and equitable healthcare to marginalized communities. Inspired by Jackson’s vision, recovered COVID patient Tom Koracick (Greg Germann) impulsively decided to jump ship and join him, hoping to find meaning through helping others.
