Reverend Edwin Peters (Ernie Hudson) saved the day in the episode of Boston Blue, which revealed family secrets in a powerful episode titled "Beautiful, Broken Things." The episode, which also included powerful scenes with onscreen daughter Gloria Reuben, revealed that Edwin Peters' wife died by suicide when their daughters were young. A visit from Mae's sister, Jill, inadvertently revealed the truth about their mother's death. Edwin was shot through the shoulder in a drive-by shooting, leading to a standoff at gunpoint in the church at the episode's end. Despite initially concealing the truth, Hudson said he didn't expect the revelation so soon. He also mentioned that the reveal about Edwin's late wife might force Mae to tell Lena about her biological father.
