Young Spock: I wanted only to help I-Chaya. He was my father's before he was mine. To lose him...
Spock: A Vulcan would face such a loss without tears.
Young Spock: How?
Spock: By understanding every life comes to an end when time demands it. Loss of life is to be mourned but only if the life was wasted. I-Chaya's was not.
