Engaged (Part II)

Back in Washington, Tony discovers that the woman who held Flores hostage has a brother, a university student based locally, and both are members of the same terrorist group. The team continue interrogating the siblings but to no avail. Gibbs, with some help from Vance, takes matters into his own hands as the team races against time to find out the terrorists' next move.
