Kathleen Dolan was a set decorator on Blue Bloods, and she has an entire episode dedicated to her in season 6. Blue Bloods ends its run after 14 seasons and throughout the long-running police procedural, a huge ensemble of characters has appeared. They are supported by an even larger team of below-the-line crew members who, though may only be recognized by hardcore fans who stick around for the credits, are critical to the success of the series. In season 6, episode 16, “Help Me Help You”, a dedication card to Kathleen Dolan appears in the credits.
