I - Surak - am loyal to my fellow Vulcans. Like you humans they come in all shapes and sizes. Some act more logical than others, some give in to their emotions.

Poor Tuvok probably always hated the ugly uniform he had to wear. It would explain his facial expressions. He never looked happy - not even in a Vulcan way.
Spock is the pride of Vulcan and my friend Serak. His Vulcan side is dominant and he never fails to amaze even me -Surak - with his logic.
