Andrew Sanderx was offered several amazing promises. But even then, he had his doubts about the truth. There were just too many things that were revealed to him that he didn't know which one of them was true! Moreover, Lieutenant Eclayne, who revealed these things, was also a newly hired soldier that only got his promotion at Major Lester's request. So he could not help but harbor doubts about this.
As a test, Arthur told him to go on specific locations of the bases. Arthur informed him that certain people would meet even though they had no purpose in the meeting. Arthur even gave him some ideas as to how to investigate this truth. Since Arthur would soon be hired, Andrew was asked to go and run around the base to check with certain people and access certain file names.
