Showrunners Gina Lucita Monreal and David J. North discuss creating the backstory for Mike Franks on tonight's 'NCIS: Origins.'

Origins episode “Flight of Icarus” are ahead! Last month, NCIS: Origins spent its midseason finale wrapping up its Gibbs-centric flashback storyline, showing the final sequence of events that led to Austin Stowell’s character joining the Naval Investigative Service.

NCIS: Origins may be centered around Gibbs ( Austin Stowell) and telling the story of his life before what we saw on the mothership — the series begins on his first day at NIS — but it’s also telling us the backstory of another character franchise fans know well: Mike Franks ( Kyle Schmid ), then Gibbs’ boss.
