Sources confirm to me exclusively that Criminal Minds and Dirt alum Josh Stewart has been tapped to play Watcher to Michael Chiklis’ nascent superhero clan on ABC’s buzzy fall drama.

I’m told Stewart, who also appeared in the final year of Third Watch, will recur throughout the season.

Exec produced by Greg Berlanti and Jon Harmon Feldman, Family airs Tuesdays at 8 p.m./ET beginning Sept. 28.
