What am I talking about? I'm talking about Henri. He has disappeared because of carelessness, the same carelessness he has always preached againt. I'm talking about the fact that when you had the gun on me, I told tou the truth. I am an alien. Henri and I came to Earth the years ago, and we are being hunted by a malicious race of aliens. I'm talking about Henri thinking that he could somehow evade them by understanding them a little more. And now he is gone. That is what I'm talking about, Sam. Do you understand? But no, I can't tell him any of this things."
