The scene opens up with James as Security in Chaldea as he is Checking the employees. And oddly enough, one of the employees there. Mash Kyrielight, noticed James' FBI Vest.

James: There's nothing prohibited on you, go on ahead.

Mash: Excuse me, but are you part of-

James: The FBI?

Mash: Yes, and what does it stand for?

James: Federal Bureau of Investigation, or FBI, for short.

Only after that, a man was getting impatient on the line, and oddly enough, he was  hiding a Pistol under his coat, so he pulls it out as loud gunfire erupts as James grabbed his Glock 19 and fired at the shooter as he saw the shooter and when he hits the shooter on the head, he noticed the shooter as a NLG Terrorist who was undercover. 

Later on...

James was in his room, cleaning and disassembling his Glock 19 as he is Checking the pistol for anything making it have problems. Then somebody knocked on the door.

Andre: You in there, Agent Saunders?

James opened the door as he hugged the others. They were let in as they were Chaldea Employees as well. They went out as Scathach noticed them while she was inside and may have recognized them as his fellow Agents. Later on, they are in a meeting as they are in a meeting as they are the security. Until multiple terrorists had been seen as they killed multiple security officers as James, being head of the Security, says this to Olga Marie Animusphere and Director Lev Lainur.

James: Sorry to interrupt but NLG Terrorists are coming in as we're their new targets, we're FBI HRT, so we'll be handling it. To anybody who knows how to use a gun, head with us to the armory. If you have no experience, get to safety.

James and his HRT Team got out of the meeting room as Scathach saw them and she wasn't wearing her usual clothing as she saw all of them grabbing weapons as she decided to go to the armory as she grabbed a M4A1 Carbine with an EOTech XPS-2, an RIS Foregrip, a Magpul CTR Stock, and a Black PMAG. She grabbed an FBI Vest and wore it as they loaded up their weapons as they put on chest rigs, and they go out to fight as they used the walls for cover but would not be intact for long. Andre grabbed his HK416, only with the Factory 14.5 Barrel, and they kill the intruders as they encountered more by their rear as they killed multiple enemies as they managed to get two of the enemies to surrender. Then they see more enemies as they were armored, and then an FBI HRT Sniper with an M107 Barrett on a Helicopter, fired at the two armored enemies as FBI HRT start breaching the windows and they made multiple suspects surrender as FBI Black Hawks were deploying HRT Teams into the building.

Scathach: These HRT guys are good when it comes to handling situations. Mind if I'd join?

James gave a thumbs up for approval. And somehow, more servants asked him and other operators if they could join. They had a whole lot, so they had to accept after discussing.
