Wow! You're a mighty deep thinker. You could out-think me right on the spot any day of the week. I just try to enjoy the books, tv shows, and movies and not out-think too much of it. I thought the Deltan thing odd from the start...but don't worry about it. I watched a youtube video that was narrated by Leonard Nimoy. He talked about all kinds of interesting things...his favorite shows...how they came up with the Vulcan pinch and the Vulcan sign of peace. He also said that NONE of the actors liked the first movie. They thought it strange....and that it didn't match up well with the tv show.
