So, it wasn’t the shame of only her, but for Vegeta, as well. So, every time either he holds back, or proceeds to push her, he feels the shame of what happened to her in the past. Using her Ki to heal her body, Kinoko thought about this, even back to all the other times she and Vegeta have sparred. They must have made Vegeta become very frustrated, which does explain all of the constant training. In a way, the princess can’t blame him for what happened, but at the same time, she forgave him. It may not sound like how a proper assistant should think, but as his sister, she would. “...and I gave it to him, by taunting him”, she concluded, almost like a guess. 

Kinoko needed him —- no, she [i]wanted[/i] him to continue pushing her, even if it meant by hurting her, by receiving the neccessary blows. She wanted him to get her angry; she wanted him to push her over the edge, in order to develop the much-needed will to try and reach him. She needed to overcome that fear bottled up inside her. Although the thought of surpassing Goku made her chuckle. “I don’t think anyone can surpass you, Kakarot”, she mused. “You’re quite the special one amongst the three of us.” 

Just as Goku began to turn away, Kinoko looked in the direction that Vegeta disappeared. Someday, she will forgive him, but she will leave him to his thoughts, and stick to her word to not mention anything. With that, the princess turned away, and followed her younger brother back to the city.
