I just read what you sent to Gail. In effect you just flat out lied to her. Xanthos IS a human being. I don't think it's a good idea to try to yank P & H's chain by misleading Gail into thinking that she has been communicating with a real horse. I had my misgivings about Xanthos' horse-hood from the start, but Zachary needed to be entertained while he was relaying for B & E, and I figured that if it became important, Xanthos could tell the probes that he had been playing a game of pretending to be a horse who could talk.
I imagine that P & H's reaction to being told that Xanthos is not a man, he's a horse, will be to be utterly convinced that Gamma Unit is whacko.
