"Trunks. Go tell Goten that I won't be able to train you two for a while." Vegeta said to Trunks.
"Why Dad?" Trunks asked.
"Just do what I told you to do, I will take you for a family outing if you do what I ask," Vegeta said to Trunks.
"Ok. Dad." Trunks said as he flew away.
"Are you sure you don't want to tell trunks about the good news?" Bulma asked Vegeta.
"Hey. Woman. Stop walking around this place when you are in this situation." Vegeta said as he went near Bulma to support her.
After Goten meets Vegeta for the first time a lot of things change in the relationship between Vegeta and Bulma.
Because of Goten's encouraging words, Vegeta was able to reflect on a few things.
How he might really be the strongest being on earth since Gohan has already retired and Goku is in the other world.
This allows him to rethink his life on Earth and wonder about how his life would be without Bulma and Trunks.
Which gives him an answer. It was not a life that he wanted to live.
He is content with his life the way it is. Which sparks his romance with the foul-mouthed woman who is willing to stick up with him.
There are a few businesses that he still hasn't finished. One of which is his relationship with Goku and their rivalry.
Vegeta accepted that Goku while alive was a greater warrior than him.
But he also knew that he still had room to grow and his rivalry with Goku was far from over.
The way he used to view Goku in the past was a goalpost that he had to surpass.
But now he looked at him as a great warrior who might be able to match him and maybe beat him even in his strongest state.
His other regret was that the lives of many people were lost because of his actions while he was working under Frieza.
He wanted to try and make up for them.
He knew that he had killed too many to be forgiven but the last thing that he could do was to protect the planet in which he was living and its inhabitants.
Since Gohan does not seem like he is going to be able to protect the Earth in the future and Goku still has no signs of return he might be the greatest hope that the Earth has.

"So Dad said he is unable to train us this week." Trunks said to Goten.
"Wait you were training under Vegeta!" Gohan who was nearby Goten said in shock.
"Goten. No matter what you can't tell Mom about it okay." Gohan said to Goten.
Luckily for Goten, Chichi was in the town shopping at that time so she was not at home.
"Still, training under Vegeta. Huh. Isn't it too early for you two." Gohan asked as he looked at the two-year-old and the three-year-old.
"Why don't we have a light spar outside when mom gets home? I want to see how strong you two are." Gohan said.
"I will pass," Goten replied.
"I will fight with you Gohan." Trunks replied.
"Alright. Then let's wait for Mom to get home before we go out." Gohan said.
An hour later Chichi returned and the three went outside for the spar.
--------------------------
The three arrived at a small island that was located in the middle of the sea.
"This place brings back memories," Gohan said.
The island that they were on was the island where Gohan's former enemy Cell obtained his perfect form for the first time.
"Goten if you want to watch the fight you can go to that place. There are a few trees that can give you shade." Gohan said to Goten who tagged along with him and Trunks so that he could watch the battle.
Goten knew Trunks would lose if Gohan was serious but he wanted to know how strong Gohan really was compared to him and Trunks.
There are not much difference in power levels between Goten and Trunks.
The only thing that is different other than their fighting style is that Trunks is slightly stronger than he was older.
For fighting style Trunks is someone who likes to go all out and overpower his enemies as soon as he can while giving them not much room to breathe.
While Goten is someone who tries to see what his opponent can do. He is someone who tries to enjoy his fight analysing his opponent's behaviour, patterns, techniques and weaknesses before bringing him down at the last second while trying to reserve as much energy as he can.
"Gohan are you ready?" Trunks asked.
"You can start whenever you want, Trunks," Gohan said to Trunks.
Gohan is in for a surprise. It seems like he is underestimating Trunks. Goten thought in his mind as he looked at the two from a place not very far away.
"Then here I come." Trunks said as he dashed towards Gohan and kicked him.
Gohan easily blocks the kick with his arm.
Trunks backed off after Gohan blocked his attack.
"Take this. Ha. Ha. Ha." Trunks then followed it up by firing rapid ki blasts at Gohan.
"I see you learned how to use Vegeta's technique as well," Gohan said as he tried to dodge all of Trunk's ki blasts.
Vegeta's technique? That's just Trunks spamming ki blasts. Or am I missing something? Goten thought as he observed the fight.
Gohan then flew towards Trunks and tried to hit him with a punch but Trunks ducked to avoid the attack.
He then used his body to tackle Gohan into the air.
Trunk's attack was similar to the attack Gohan used in the past.
The one that he used on Raditz many years ago that sent him flying away.
"Double Buster." Trunks said as he launched a powerful ki-wave at Gohan who was sent into the air.
"Not too shabby. Huh. Masenko." Gohan used the technique that he learned from Piccolo to counter the attack.
The two attacks clashed.
However, as soon as the attack clashed Trunks transformed into a super saiyan and increased the power of his double buster even further.
"Super Saiyan?" Gohan was caught off guard as he was taken aback when Trunks transformed into a super saiyan.
This creates a small opening. The opening was enough for Trunks to win the clash as Gohan is hit by the double-buster.
Smoke covered the area where Gohan previously was at.
"I am impressed Trunks," Gohan said as he wiped away the smoke with his hand.
His clothes were destroyed and he seemed to be a little bit damaged by the Double-buster. But he was still in good enough condition to fight.
For reference, if Gohan's health was 100 when the spar started he was at 80 after being hit by the Trunk's powerful tackle and the double buster.
"Alright, Trunks you win," Gohan said while giving a small smile as he descended into the ground.
Gohan got a lot weaker during these two years. He might lose to Vegeta if he doesn't use Super Saiyan two. Goten who was watching the battle concluded.
Goten knew Gohan had thrown in the towel as he did not want to fight seriously against Trunks but Goten was still able to gauge Gohan's strength as he was still visibly hurt and injured by Trunk's attacks.
