Tom Selleck, who plays New York City Police Commissioner Frank Reagan in "Blue Bloods," recently revealed that his favorite episode of the show is "The Job" from Season 2, Episode 12. The emotional episode tackled the sensitive topic of 9/11 and had Selleck fighting back tears while playing out the story of Frank dealing with survivor's guilt after learning a friend was dying from health complications related to the tragedy. The episode also featured the Trade Center Memorial, which "Blue Bloods" was the first show allowed to show right after it was finished.
