No need to Shield your eyes from this NCIS news: Catherine Dent is coming on board for two episodes this fall as Whitney Sharp, a former agent who shares a past with Ducky.

David McCallum's medical examiner character will be featured in one of the show's promised "origin episodes" and his relationship with Sharp will play a major role in that story.

Playing a law enforcement type should come easy for Catherine Dent.

EW reports that the former star of The Shield will be on "at least two episodes," meaning this role could continue even after November sweeps. That certainly sounds intriguing.

Dent’s character is described as an educated, bright, and extremely capable federal agent who had an eye for talent and a tongue for persuasion back in the day. No surprise.

Thoughts on this Ducky-centric, flashback-heavy story arc?
