Spock estimated he had carried the weight on his back for 5.92 km before he began to see lights on the horizon. With the time to himself and the unconscious body on his back he evaluated another emotion outburst of the day. Attacking the beast was not logical, the odds of coming out alive.001625 to 46. The adrenaline apparently made the odds not matter any longer and Spock had succeeded, he didn't want to admit it but it was exciting.
The morning cam and Spock at the end of his stamina dropped his burden off his back. From across the plain he was his father making his own way out to the desert, with the sun up and the desert nightlife falling back to the shade. Sarek saw Spock and began to run to him, Spock, spent as he was, simply waited for his father to reach him. Surely four or five extra minutes would not alter my state of being, thought Spock.
Sarek reached Spock in a flurry of billowing clothes, Spock, attempting to give his father a Vulcan acknowledgement, bowed. His father, Vulcan as he was, had an illogical soft spot for his son; he grabbed his shoulders and examined his son for damage.
"Your mother has been worried; it was illogical to leave at night." Spock, gaining new energy to impress his father, Spock answered,
"What had overwhelmed my logic has been eradicated, it will not happen again father." With no more words Sarek grabbed the forgotten boy and walked with his son to their humble home.
