MTAC

"Tony, with me." Gibbs said. They approached Vance's office only to have the secretary say that Vance was in MTAC. Gibbs and DiNozzo entered MTAC to find Vance communicating with an admiral. When the conversation ended, Vance turned to them.

"What do you have for me, Gibbs?" Vance asked, regarding both him and DiNozzo.

"What do you make of this, Director?" Gibbs asked, holding up the microchip. Vance could not contain his surprise.

"Where did you find that?" Vance asked. "Latham just told us this morning that they were all accounted for."

"We found it in the quarters of our dead Navy commander. He too had an incision in his wrist." Gibbs added.

"But he removed the microchip himself?" Vance asked.

"Maybe he discovered that he was being tracked that way?" DiNozzo added.

"The Intel that was downloaded here says that an attack in D.C. is pending. It was downloaded this morning." Gibbs explained.

"May I?" Vance asked pointing to the chip. Vance picked up the chip and handed it to a technician in the room. "Access the Watcher Database using this chip for me." He ordered. Up on the MTAC screen, the information that had been printed was found along with updated information on the target.

"NCIS headquarters!" Tony shouted.

"The target is us." Gibbs added looking at Vance.

"I am calling SecNav, and I am having the building evacuated." Vance announced.

"Wait, we don't know exactly what these terrorist plan to do. It could be just a Cyber attack." Gibbs said.

"Highly unlikely." Vance said, as he initiated the evacuation. "If you want your team to continue to investigate, I won't argue with that, Gibbs."

"Let's go." Gibbs said, nudging Tony to leave the room. "Catch Ziva and McGee up to speed."

Squad Room

"Hey guys." Tony said as he ran into the room. "We read some stuff of that microchip. NCIS headquarters is the target of a terrorist attack."

"Oh my!" Ziva said. McGee stood up slowly in reaction of the shocking news.

"Vance is evacuating the building. Boss wants us to find out how the attack will take place to try and stop it." Tony explained.

"McGee." McGee answered his ringing cellphone. "On my way, Director." McGee said. "Vance wants me to join him in MTAC to hopefully get more information off of that microchip."

"Hey, remind Vance though, that the microchip does have a tracking device, McGee." Tony suggested.

"Sure Tony." McGee said sarcastically, rolling his eyes, at the idea of telling Vance to deactivate the chip.

"McGee!" Tony said sharply, after being blown off. "Stratton has a microchip. If he or any other Phantom eight are in the building, you might be able to track them now, McEgghead."

"Agent David." Ziva answered her ringing phone. "Yes, I will take care of them, Gibbs."

"Gibbs wants me to personally escort Abby, Ducky, and Palmer from the building."

Tony circled, noticing that he was the only one around. The elevator doors opened, to reveal Agent Fornell.

"Fornell, how did you even get in here? The building is being evacuated." Tony said sarcastically.

"Where is Gibbs, Tony?" He asked, looking DiNozzo over and remembering what Gibbs had shared with him earlier.

"He is in MTAC." DiNozzo answered.

"No, I am here." Gibbs said as he reentered the squad room.

"What is up?" He asked Fornell.

"We traced the weapon down that killed the NCIS agent and the two terrorist." Fornell started to explain, acknowledging that this was not a very private area to discuss this, looking at DiNozzo and around the room for anyone else listening. "Can we talk in private?" He asked Gibbs.

"We have a situation here, Tobias, just say it." Gibbs shot back, in obvious irritation.

"The gun used to kill them is registered to Secretary of Navy Clayton Jarvis." Agent Fornell whispered to Gibbs. Gibbs just stood there examining Fornell, as Tony's jaw literally dropped. "We don't know if he actually fired the weapon. . ."

". . .but the weapon was registered to him." Gibbs added shaking his head in disbelief. "When this situation is resolved, I will confront him about it."

"You are right to be concerned about your team, Gibbs." Fornell added.

". . .only if he really is the one that killed them." Gibbs tried to defend his SecNav.

"Gibbs, come on. . .what are the chances that someone stole his personal weapon and used it to kill the terrorists and the NCIS agent." Fornell yelled at him, trying to lay out the facts in front of Gibbs. "I know there are no such things as coincidences. But, come on Gibbs. . ."

Gibbs shook his head and started to move away from Fornell.

"DiNozzo." Tony answered his ringing phone. "Okay, thanks McGee, I will tell Gibbs."

"Boss." Tony said, which caused Gibbs to stop before he left the room. "MTAC is tracking another microchip in the building."

"What can I do, Gibbs?" Fornell asked.

"Help us find him. He is somewhere in this building." Gibbs said, drawing his side arm. "Tony?"

"I'll start downstairs." Tony said heading for the elevator.

"Fornell, stay here and guard MTAC." Gibbs ordered, as he followed Tony to the elevator. Gibbs punched in another floor on the elevator panel.

"Be careful, Tony." Gibbs said. Tony shook his head looking down. Gibbs went to autopsy and Abby's lab. Tony went to the evidence garage and the evidence lockup. Tony entered the room with his gun drawn with a flashlight, flashing the light quickly around the room.

A quick, bright flash from behind the evidence lockup gate caught his attention. Tony cautiously approached the gate.

"Gibbs, I might have something." Tony said into his earpiece, when he found a box that appeared to be sparking. He quickly came upon the box as well as the source of their threat. Tony quickly pulled a gun on Casey Stratton standing there with a remote detonator near the box strapped with dynamite.

"There is only five minutes left on this timer, DiNozzo." Stratton said.

"Gibbs." Tony said again into his earpiece.

"Right here, Tony. Put that down, Stratton." Gibbs said, as he too entered the area. Tony turned to see Gibbs join them, as well as McGee, Fornell, and Vance.

"I have deactivated that remote, Stratton with this signal jammer." McGee added.

"That bomb is still set to go off." Stratton informed them. Vance walked over to it and opened the box. Without hesitation, he snipped one of the wires, which deactivated the bomb. Then he yanked out the wick to the dynamite.

"Whoa, Director." McGee shouted." I am sorry about that. Good work, sir." McGee said, shocked that he effectively disabled the bomb.

"That a hobby of yours, Leon?" Gibbs smiled at him suspiciously. Vance just smiled deviously. Now that he was both relaxed and confident that the threat was over for now, Vance ordered that Stratton be taken to holding. Gibbs and Tony went over to handcuff the suspect. Tony pulled Stratton's gun from his holster.

"Tony, let me see that gun." Fornell said quickly. "This. . .could be the gun that killed both the NCIS agent and the two terrorists." With Gibbs holding Stratton, Tony handcuffed him and they took him to holding.

"Or it could be another coincidence." Fornell whispered into Gibbs' ear, not totally convinced that Jarvis was incapable of murder.
