"Sometimes you have to be hard on your children to prepare them for what they may face in the future." A pause as a tension to Vegeta's shoulders returned again, thinking back to his own poor parenting he had done. His own methods had been mostly selfish, though still laced with the need for the boys to learn to fight. He had used them, especially the Trunks here, to strength himself first, and only secondly considered Trunks' training. Something he was trying to make up for now.

"But... with balance. I've learned." He knows he hasn't been the best father, and also that the Saiyan upbringing he had was not the right one for his children. His children at least had Bulma around to help counter his ways, unlike how Yondu had it.

"His father is dangerous?" Yes, lets get this back off him, Vegeta doesn't need the reminder of what he's done in the past.
