So Jun used Bach's "Little" Fugue as an example for fugue in the newest chapter. And it's unavoidably the most well-known example when learning fugues in music, as well as the most known to be played on an organ -- which reminds me of the Alteration Engine in S2, as it was similar in shape of one that Vanitas played to save Chloé. (Feel free to add how it could connect with the rest tho.)
Just for the added flavor, fugue comes from the Latin noun fuga, as well relates to the verb fugere which means "to flee", or fugare "to chase". The reason for this is because fugue in music is played in parts where it starts with one voice playing the main melody (the subject) and later has the second voice enter with the same melody but differs in its pitch and key (the answer) thus complimenting each other and creating a harmony, a third voice can enter later and so on.
It's similar to having a conversation on the same idea (subject) but with different views (the answer), and it keeps going back and forth as a chase or fleeing.
In case of Astolfo, which Lady Archiviste comments at the end of ch59, it is his hatred that he keeps chasing after and keeps him going/surviving, but at the same time fleeing from himself as he cannot forgive himself for what he has caused so far due to his trauma.
The different answers can also be what others have weighed in about Astolfo's path, such as Roland wanting him to heal and trying to redirect him from a destructive path he is on while the Church is shaping him into an ultimate weapon against vampires.
So a very cool analogy Jun made with fugue.

Lady Archiviste: "A fugue of hatred that has forgotten how to stop."
Me: "Just add a coda and it will be okay lol"
