Airport Guy
There seems to be agreement on this board that the guy at the airport who recognized Tony Wilson was a company employee who was testing Wilson. I disagree. I think the real Wilson was the man they killed as Hamilton's "cadaver match," and Hamilton took Wilson's identity (probably moving him to a new place).
Remember when the Asian guy with the funny mustache gave the new Wilson the press clippings and diploma? When Wilson said, "you can't fake these," he told him the diplomas were indeed real. Perhaps they belonged to the real Wilson, as did the paintings.
As far as whether the company wanted the reborns to fail the first time around so they could come back and recruit new clients, that is definitely a possibility. Perhaps they set them up to fail. But I really don't think so. I think they try to help people succeed, knowing full well some will fail on their own and have to come back, where they will either recruit new clients, or be used as cadavers.
