Jacob caught the code that the Vault Dweller gave him. Was he involved with the Enclave somehow? That was one possibility yes, the other was that he was an NCR agent who somehow was catching on to Jacob's charade. It just wasn't worth the risk, so in the instant after James used the code, Jacob fell behind his lies once more. "Can't say I bother with old word broadcasts." Jacob said, then added for good measure. "Does the Eagle Still Fly sounds like an American propaganda song honestly, and I can't say I've heard it before." Jacob finished, content with his lie. He gave what appeared outwardly to be an amiable look, though underneath the desk, where the dweller's vision was obscured Jacob gripped his plasma pistol, ready to whip it out should things go south. He would need to keep a very close eye on this Vault Dweller. If he made assumptions, and decided to even suggest that Jacob was a member of the Enclave to the rest of the group, Jacob would kill him. In a similar subtlety, GU-DR rotated it's arms so that the flamer was aimed, albeit nonthreatening at the Vault Dweller. It had also picked up on the code and was growing suspicious. Such information was dangerous, and could hinder the mission should it be leaked. The censors were obviously not doing their job, keeping such codes out of the hands of the general public.
