After being away for five years, Bulma is invited to Kame House, where Master Roshi and Krillin have been living. Goku arrives shortly, and introduces his son, Gohan, to everyone. Master Roshi points out that Goku named him after his Grandpa Gohan. Bulma is impressed with how proper Gohan’s speech is, in light of who his parents are. Goku tells her how Chi-Chi is quite strict about the education Gohan receives, and how she does not let him train Gohan.
