A/N: Thank you to Cara2012 for letting me use the lullaby in this ch.! I translated it to Japenese, though. It was originally in Swedish. Here's a link to Cara2012's profile:

"Go find the strongest Sayain and bring him to me, Vegeta."
Freiza demanded, and Vegeta growled lightly. He muttered something inaudible, and walked to the nursery. Once in there, a baby with black hair instantly caught his eye. He turned to the baby, and talked to it quietly for a little while.
But as Vegeta was leaving, he heard the baby cry in despair from a terrible vision. Vegeta suspected it to be a nightmare, and he instantly ran over to Kakarrot. Goku cried even louder, and the fur on his brown tail was standing on end. Vegeta quickly used his tail to grab the younger Sayain's tail, and he cradled the tiny baby in his arms.
Goku calmed down slightly, but was still crying, so Vegeta did the first instinct he had.
He sang a beautiful lullaby to the little baby.

Vegeta sang to the younger sayain, who eventually calmed down. The little sayain, Kakarrot(aka Goku), had just woke up, but in the middle of the night.
"Waugh! wa-Hmmm…"
The little baby slowly stopped crying, and began giggling. Vegeta sighed, and began rocking the baby back and forth. Eventually, Kakarrot had fallen asleep, and Vegeta had to leave him be.
"I hope I get to see you tomorrow, third class sayain," Vegeta smiled, and he walked quietly off.
But the 5 year old Vegeta didn't know that Kakarrot wouldn't see him again for twenty years.
