In Ada's report # 2, Ada says the only reason she came across Luis was because she intercepted his email for help which he sent to an old friend from college who he thought was still alive. I'm thinking this is John Clemens, the Umbrella employee Ada used as told to do by her organization and, who also is a non PC character in RE2. And at one point in RE4 Leon tells Luis about how he was in the RC Incident and Luis didn't seem to informed on that situation. This isn't really important. Just wondering though
