"The ending is a bit of a cliffhanger, less so than in the previous 2 seasons, but it’s definitely a launch to where we want to go in season 4," says creator and showrunner Matt Miller of his Fox drama, which has faced a lot of off-screen drama over the past year. "Since we’ve already mapped out in detail what season 4 looks like, it will definitely be a bummer if we don’t get to tell that story."

I hope it gets renewed but doesn't Damon Wayans want off the show?

"In fact, it was more of a huge cliffhanger that informs what could happen in season 4," says Dino-Ray Ramos of the stunning season finale that aired while the future of the Fox series (https://forums.previously.tv/topic/89806-lethal-weapon/) was up in doubt.
