According to showrunner Rick Eid, the reason for Det. Kevin Bernard’s departure from “Law & Order” was not mentioned during the big crossover premiere because the explanation was saved for the second episode of season 22, titled “Battle Lines,” which will air on September 29th.
“It’s a small mention,” showrunner Rick Eid told TVLine in August 2022. “It’s in the time-honored tradition of Law & Order, where it’s very short and it says, ‘Carry on. Here we go. We have to solve the case.'”
As seen at the crossover event, Supergirl and Mortal Kombat actor Mechad will replace Brooks Anderson as the new detective, Jalen Shaw. The former SVU guest star spoke to Entertainment Tonight about the opportunity and his character, who he describes as “an adrenaline junkie-turned-undercover narcotics-turned-homicide detective.”
“It’s a dream come true in many ways,” he told ET. “I grew up watching the show, so it’s surreal.” Explaining what kind of cop his character is, Brooks said, “He knows the law inside and out. Also, he can be rude when he has to, when duty calls…you see the wolf.”
