After the first time traveling:
Bardock: This guy's fighting ability is really low. It seems that he needs to ask Raditz to take care of him from now on. Just call your name Kakarot. Next time dad will come find you.
Kakarot: Wow~Wow!
The second time through:
Bardock: I want to marry your second child!
Dad Shimura: Huh? Not yet born...
Bardock: It doesn't matter. I have money (as a mercenary), I have strength (as a Saiyan), and I'm not bad looking, right?
Dad Shimura: Okay then!
Sixteen years later, the House of Everything.
Bardock: I'm your fiancé.
