Let's adopt this puppy.

Oliver returned to his room, his mind filled with the new information he just received. It left him with many questions which can't be answered logically. 

He asked the old man about the friend who accompanied him but the old man said that he can't recall how that man looked. He said he could recall Oliver only because of yesterday's incident. 

'Maybe the old man mistook me as someone else. Whatever he told doesn't ring a bell at all.' Oliver thought. It is the only plausible conclusion he could come to. 

'Let's see. He said that he would show me the jeep in which I came here. Maybe it will answer my questions.' Oliver thought. He can send the jeep's registration number to his assistant and ask to whom it used to belong.

By the time he returned, it was already night and everyone had dispersed to their own room. Like yesterday, the guard/ receptionist was in the lobby and greeted him. 

Oliver nodded his head and took the elevator to his floor.
