Canto II really intruiges me from an adaptation/inspiration standpoint because it did something really noticeable in a way I didn't really notice the other Cantos do.
And that's applying character traits heavily associated with one character to a different character with an equally clear explanation.
Gregor and Hermann keep the antagonistic relationship between Gregor and his family (remains to be seen if Gregor and Hermann are blood relations, a literal family like the novel or in a more metaphorical sense)
Sinclair, Kromer, and Demian are still largely in their "focus", "tormenter", and "savior" roles respectively, just expanded upon and dramaticized to fit the setting.
But then you get to Rodya and Sonya/Rodion and Sofya and it's like they did a freaky Friday "personality flaw swap" in addition to both being genderswaps of their namesake.
From what I know of crime and punishment, Rodion was the one who repeatedly attempted to use high-minded theory and big words to justify their actions, justifying the murder under the logic of "Now I can go achieve great things, so it's a worthy sacrifice", whole Sofya was the grounded confidant who eventually followed Rodion into his punishment to stick with him out of devotion.
Very interested to see where Project Moon takes Rodya and Sonya from here, because, as of right now, they're really conspicuous in this shuffling of "role", in a way Gregor and Sinclair really weren't.
