By using the Guardian of Forever, Kirk, Spock, and
the historian Erikson explore the planet Orion's past. However, upon returning
to the present, no one seems to recognize Mr. Spock; the U.S.S. Enterprise
first officer for the past five years has been an Andorian named Thelin.
A search of the U.S.S. Enterprise's memory bank reveals that Spock, the son
of Sarek and Amanda died while still a child; his death caused the couple
to breakup.
Spock recalls that during his "kahs-wan" -- a Vulcan coming-of-age ritual -- Selek, Spock's distant cousin, had saved his life. Spock realizes that to put the present right again he must return to the past and become his own cousin to save himself.
Returning to the Vulcan of his childhood through the Guardian, Spock presents himself to his younger self as Selek, and subsequently saves the boy's life. In the process young Spock's pet "sehlat" is mortally injured. The boy chooses to compassionately end his pet's suffering and in doing so sets the young half-human, half-Vulcan on a path toward embracing Vulcan traditions. Upon returning to the present, Spock finds the timeline and his place on the U.S.S. Enterprise restored.
I don't have the Captain's Log for this episode yet, sorry.
