Also absolutely not necessary but would be fun, if Kirk aptly gets A Tale of Two Cities, which they borrowed and wove in several intertextual elements - Khan needs to be paired with his own parallel volumes: Either Moby-Dick (implicitly invoked throughout the film) , Dante's Inferno, or Milton’s
Paradise Lost, first cited in Space Seed.
All suggesting aspects of Khan’s character.
That said, surprised 5 pages into
The Wrath of Khan thread (derail not withstanding), anybody has yet to share the actual
Khan prototype.
