What Happened to Calvin and Charley?

Calvin and charley report the same basic series of events. The two were floated aboard the craft, but they were taken to different rooms. Calvin reports being put on a transparent table so that the creatures could work imand that might represent the same thing that charley reported. Both objects made passes around their bodies. So far both are reporting the same things. What about the period where he said he was left alone by the creatures? That may be explained by something in calvin's report.
