Several characters are returning for part 2 of Blue Bloods‘ final season 14, even as new ones are added. The Tom Selleck-led police and family drama is a fan favorite in part because of the dedicated cast that has enthusiastically returned year after year as members of the Reagan family. Most of Blue Bloods’ best characters are again returning for season 14B, which begins on October 18, 2024, @ 10 PM EST on CBS. Several characters are also returning for the series finale.
