Next Tuesday on CBS’ NCIS, a case in the present will evoke troubling memories of Abby’s past — and TVLine has a first look for the sure-to-be-emotional hour.

Setting the stage for the flashbacks is a car accident involving a Marine, a death that reminds the lab wizard (played by Pauley Perrette) of the first “case” she ever worked, as a preteen (Brighton Sharbino).

But as seen in this promo, the resurfaced memories will rock Abby to her core, to the point that Gibbs must take notice that she is no longer bringing her “A game.”

Show boss Gary Glasberg told TVLine the episode will answer such questions as “When did Abby first start develop an interest in forensics? And in people? In bodies, and in clues, things like that?” All told, he promised “lots of great little prizes” for longtime viewers.
