I thought that Undercovers
was more Josh Reims's show, really. Given how many other things Abrams had to oversee, it was probably co-creator Reims who was most responsible for the day-to-day showrunning. Just as Fringe
's day-to-day showrunners are Jeff Pinkner and J. H. Wyman, and Lost
was run by Damon Lindelof & Carlton Cuse.
