Goofs

 * John mentions Lyla is working in HQ, however, the conversation takes place in HQ. It is unknown whether John means there is a worldwide HQ of A.R.G.U.S. where Lyla is working, or it is a writing error.
 * The building was later confirmed to be the HQ of A,R.G.U.S. in when the exterior of the building is seen, which proves that this goof is in fact a writing error.
