@Hillan Alright, I guess I'll give vocalising his thoughts about everybody a shot. Considering that Yuudaina's been there probably a month or so as of the game's start point, and therefore probably doesn't know everything about them, I imagine his impressions are about as follows:
Ax Colt: "There's still things to get excited about even as you grow older, sir. Beyond killing pirates, that is. Find your passion."
Freyja: "Is this how a Vice-Admiral ought to act, ma'am? Have you considered that setting a good example might improve the Marines under your command?"
Edward Woodall: "Whoever said you can't still do amazing things? You got this far, after all. Only, please leave the punishments to me, if you don't mind, sir."
Irwin Kendrick: "I see you too are a man who takes order seriously. If every Marine in the base had that attitude, G-5 would be much better off."
Dedric Olari: "I think maybe "follow orders to the letter" ought to apply to you; addendum, "and not a letter further". Still, you get the job done well enough."
Wonka Williams: "You're practically a model Marine when it comes to attitude. Your conduct needs work, though. Focus on your mission, not the girls in it."
Nothing to say about Jiu Cheng-Shu, who doesn't exist in the Characters tab yet. Oh, and as Vetis says, here's hoping you recover quickly.
