"It is something! Training you is easy because you're smart at figuring things out. Even if you don't totally understand it you get it, that's smart." Like how Shu had always been able to fire Ki, even if he wasn't quite sure how it worked. What he needed help with more than anything was refinement, learning tricks and techniques came easily. Probably a byproduct of being a Saiyan, it must be so difficult being naturally adaptable and strong. Smiling, Yumi folded her arms over her chest, leaning back in her chair casually. "If you keep training then you'll get better, that's how it works. And I don't think you've needed saving much. If anything I think you've saved other people. Like back when we fought that big monster, remember? Viral and I couldn't beat him, so you and Takeshi came and saved us. You saved us. And I still haven't thanked you for that yet, have I?" Hm, how to repay someone like Shu. A gift, she supposed, that seemed the most sensible. How she would find a gift suitable for such a boy though was a bit of a mystery. He did seem to enjoy smoothies back home, perhaps she'd make some for him. Or try training him in his staff, she sort of knew how to wield one from her own martial arts experience. 

Trying to compare Shu with his brother wasn't working, not with the whole boat analogy anyways. Probably best just to move off of that complete, unless Yumi wanted to fry the little Saiyan's brain. Instead they'd move onto more simplistic terms, something that Shu would have no issue understanding. They could always get help from someone else on this topic too, someone who, like Shu, was prone to anger. Immediately Viral and Takeshi both came to mind, being the foremost people who she could draw parallels with Shu. "Viral's energy might be different, but don't you think the same thing happens? He gets angry, his energy spikes and he changes. Even if it's different energy the way it works is the same... I think. Vegeta would know more than I do about that." Perhaps just asking Takeshi was the easier route to take. Best? Probably not, but definitely the most simple. While she had agreed to help Shu out Yumi wasn't beyond thinking they might need other help too, she couldn't sort this out on her own. Smiling sadly hearing Shu express his fears she reached out again, giving his hair a gentle ruffle to try and perk him up. "It's okay to be scared, but you need to try and be more confident too. We'll figure this out, and we'll do it soon. Then you won't have to be afraid of getting angry anymore."
