While responding to an anonymous tip about an alleged terrorist plan, an explosion kills two members of Agent Paula Cassidy's team (attached to the DoD at the Pentagon) and injures her; Gibbs and company investigate; feelings and emotions run high. Both Ducky and Abby produce answers, then Ducky raises more questions; Abby finds it hard to imagine that Ducky may be wrong about something. Paula advises Tony on an important matter. The gang do more analytic work, then McGee finds a clever new program, which helps to explain how both Ducky and Abby are right. Gibbs, Tony, Ziva, and Paula attend a memorial service, and Paula takes a major step. Later Tony speaks with Jeanne.
