Ernie Hudson hopes Blue Bloods fans can suspend their disbelief about him returning to the universe - with a brand new role - in Boston Blue. During an exclusive interview with Us Weekly, Hudson, 79, recalled appearing in a 2018 episode of Blue Bloods before booking Reverend Peters in CBS' spinoff, joking, "That was a character who looked like me and I think he was distressed." Hudson acknowledged the difference in roles. "I haven't seen that episode [of Blue Bloods] - if ever - but no. So it was a very, very different character," he explained.
