Network television doesn’t really do surprises anymore, but it has gotten very good at reunions, and the past few weeks have delivered a steady drip of franchise homecomings for one of TV’s longest-running properties. Mark Harmon was first confirmed to return as Leroy Jethro Gibbs for NCIS: Origins Season 3. Not long after that, Michael Weatherly was announced for his own season-long return in NCIS Season 24, making him the latest major franchise veteran to find his way back.
