she changed her mind fast, one of the smartest people he's attacked so far lol.
he's already gave her a potential up if she's still S+ top rank swordsman AND has magic to augment, support or even just have if needed she'll be insane and now he's even giving her a spar that should help a lot, from being ready for anything and to not underestimate an opponent just because of their weapon just from the first attack, and probably more if it continues.
other than thinking she deserved better than how things went for her in the first timeline, he's got a bit of battle junkie himself and a desire to see impressive things so at least a little of it is him wanting to see the monster she'll become with magic+swordsmanship, even if he risks having to fight her one day. plus she's a bro(sis?) she wasnt mad at him for grabbing the arm to stop the guy specifically i dont think, i feel like its more her worried that the princess might end up leading herself on from him doing things like that. i could be wrong though....
