Re: Why was Sulu played off as a normal person but Chekov as a caricat I thought Shatner was a Canadian Jew. My take is that Vulcans can hear in a wider audio spectrum than we do, they can hear sounds we can't. Some of the family name is "missing" to Humans. Amanda through the years has learn to make sounds, pronouce words, that she actually can't hear herself. It's like when we make sounds so high pitched that we can't hear what's coming out of our mouths, but dogs will react to. To another Human it just seems like you're slowly exhaling.
