That is a very poetic form of decorum, which reminded me that stories can be told in poetry. The fact that they went into so much detail for each individual character, as Kekoa brought up, I think just goes to show the poetic nature of his writing.
I liked Minerva's persuasion was based on if you leave, those who died will have died in vain, as was brought up by Kevin. I think too many times as we devote our lives to certain things we feel an obligation to continue. That lays a perfect kairos if you are trying to convince someone to keep doing what they are doing, it's almost like an addiction. This story really depicts the art of 'guilt tripping' you could say, which it turned out for the better of course.
But just as Eli said, we tend to follow those same patterns today, which I completely agree with. The art of persuasion has been and is a very valuable skill to have.
