Jake’s prison cellmate in “The Big House” is named Caleb.
Caleb is played by Tim Meadows and is introduced as Jake Peralta’s cellmate after Jake and Rosa Diaz are sent to separate prisons. He is a cannibalistic serial killer, a startling contrast to Jake’s anxious, rule-following approach to prison survival. Despite his frightening reputation, Caleb becomes an important ally during Jake’s incarceration.
“The Big House” is a two-part season 5 premiere. Part 1 aired on September 26, 2017, and Part 2 followed on October 3. Jake tries to obtain a cellphone and secure protection while the squad works outside prison to expose Lieutenant Melanie Hawkins and clear Jake and Rosa’s names.
The other names can also be confusing because Romero, Granville and Seamus Murphy are all connected to the prison storyline. Romero is an inmate involved in the prison’s drug operation, Granville is the warden, and Seamus is a mob boss who helps Holt. Caleb is specifically Jake’s cellmate.
