NCIS: Shell Shock (2)

Part two of two. Tony reviews satellite footage of rebel forces in the Middle East and spots Kersey among a group of insurgents, concluding that Joe Westcott's fear of him was well-founded. Back at HQ, Abby creates a 3D computer model of the attack that occurred in Afghanistan and Joe dons a virtual-reality headset to relive the traumatic events. Will it jog his memory?
