Warning: SPOILERS for 9-1-1 season 8, episode 18, "Seismic Shifts."9-1-1 season 8, episode 18, set up many storylines for season 9, but it most importantly pointed towards Bobby Nash’s successor as the 118’s fire captain. Peter Krause’s exit from 9-1-1 was monumental for the long-running procedural, as it was the first main character death in the series' history and disrupted every ongoing storyline. In his wake, Bobby left a grieving widow, Athena Grant (Angela Bassett), and a team full of lost firefighters: Henrietta “Hen” Wilson (Aisha Hinds), Howard “Chimney” Han (Kenneth Choi), Evan “Buck” Buckley (Oliver Stark), Ravi Panikkar (Anirudh Pisharody), and Eddie Diaz (Ryan Guzman).
