How Blue Bloods' Joe Hill Is Related To Frank Reagan
By MARK D. MCKEE
When Joe Hill (Will Hochman) showed up on “Blue Bloods” as a driven and capable officer, it was clear to viewers that there was more to him than meets the eye.
Eventually, it is revealed that Joe Hill is Frank Reagan’s grandson. Frank was unaware that his late son Joe had a child and Hill was using his mother’s maiden name.
In speaking with TVLine, Wade said, “ What we tried to write, and certainly what Tom [Selleck] played, was 99% a family man faced with his worst nightmare.”
Hill's presence has a way of completing the Reagan family tree, and it seems that it's only a matter of time before Hockman returns for a regular role.
