Re: Spock Lying
TUC went to great lengths to explain that he wanted others -- not himself -- to merely exaggerate, omit, etc.
I don't know if Vulcans can't lie, or most often choose not to. If it's just a myth, it would be very useful for Vulcans to further it. Anyway, he's only half-Vulcan.
I don't think the ability to lie would be genetic. More than likely the Vulcan aversion to lying would be cultural and learned. Spock is culturally a Vulcan.
Spock and other Vulcans have lied, most notably Tuvok who work undercover in the Maquis.
The boring one, the one with Khan, the one where Spock returns, the one with whales, the dumb one, the last one, the one with Kirk, the one with the Borg, the stupid one, the bad one, the new one, the other one with Khan.
