Now supposedly a Vulcan cannot lie. In TOS season 3 Spock is believed by the Romulan commander for this very reason. He states Kirk is erratic and basically out of his mind. He states that Kirk has no orders to do as Kirk did...
Yet, we find out that Spock actually knows the orders to go into the Neutral Zone and somehow get aboard the Romulan ships and take a cloaking device. We also know that he and Kirk have planned it together (but bones was ignorant of it until the plan was already in effect).
So, did Spock word it in such a way that it wasn't exactly a lie, but either a very strong stretching of the truth, OR was he somehow skirting around the issue?
It seems after watching the episode, that this is never explained, leaving it more appearing that Spock, a Vulcan who could not lie, actually did lie, in a very big and obvious blatant lie. How is this possible? Especially seeing in some ways it is the crux of the episode. I thought they'd explain it, but they did not.
