The Chosen One can connect to a video feed coming from the active PoseidoNet Station: "Control Station ENCLAVE" in the Gecko nuclear power plant via the reactor maintenance terminal. The video feed only functions one way, so they can see the Enclave officer, but he has no idea who he is talking to.
The following is based on Fallout 2 cut content and has not been confirmed by canon sources.
Irritating him at any time during the little "chat", he will determine the location to be at the Poseidon Atomic Reactor #5, and threatens to deploy a vertibird assault team to Gecko. The assault team does not show up, as the random encounter was cut due to time constraints.
End of information based on Fallout 2 cut content.
