Thanks for the chapter!
Think it's good that she's not taking the peace as a given and that another war won't break out at some point. Even with peace need eternal vigilance as leaders change for better or worse. Take Germany for example. Hitler was unreasonably prejudiced against Jews, non-whites, had untreated syphilis, and yet was charismatic enough to get the country to make him leader and follow him into conquering other countries and make his prejudices their own until defeated. Even stranger was being able to do all this with terrible logistics that makes many wonder how anything got done or supplies arriving where needed and such.
Although as a student she seems to be pushing too hard and getting her priorities mixed up. Instead of being the strongest in the class she should aim to be the strongest she can herself can be.

Bet she's the descendant of one of the female members of his former hero party hence his comment.
