Dylan Walsh's Mayor Offers Erin an Opportunity on 'Blue Bloods' (PHOTOS)
Dylan Walsh's Mayor Peter Chase presents her with a life-changing opportunity in the November 15 episode. As previously revealed when his casting was announced, he wants her to run for the Manhattan District Attorney's office. Will she accept?
See who's changed the most since the series debut in 2010.
In "Friends in High Places," Henry (Len Cariou) works as an investigative consultant for child services, and he and Danny (Donnie Wahlberg) butt heads over a case involving a man who is volatile toward his wife. Frank (Tom Selleck) is caught in the middle of an ongoing battle between the NYPD and the FDNY. (Dan Lauria returns as Stan Rourke; the fire commissioner and Frank went head-to-head in Season 6.)
In honor of two returning actors in the 200th episode, we look back at some notable recurring characters.
