"I love episodes in Blue Bloods where the family all has to rally to the same cause, or is affected by a situation -- if the crime somehow impacts everyone," says Donnie Wahlberg, while Bridget Moynahan explains, "I think different people are responding to different relationships on the show in the family dynamic."
