Last night's NCIS treated viewers to paralleling plots in which the team was called to investigate the mysterious death of a Marine, while Vance discovered something that made him question ... everything.
Fortunately, Gibbs, helped him gain some perspective. As for when Vance will return full time, and his mental state at that point, time will tell. Read our NCIS review for a full breakdown of "Hereafter."
Looking ahead to next week, Brian Dietzen plays a key role for the first time in awhile as Ducky and Jimmy disappear while transporting a body from a crime scene, and the team races to find them.
