1) Caliborn wants to be "Bros" with Dirk-> Doc Scratch is Lord English& #39;s own customized Puppet Dirk, designed to delegate all the hard work of timeline maintenance Caliborn doesn& #39;t want to think about to a smartass supercomputer Halquis subservient to his will.
2) Lord English is Caliborn& #39;s fantasy of exerting Power, the single and only thing he values (and the single and only thing he admires about Jake). In a sense, Lord English/Doc Scratch is a twisted, dark fantasy mirror of Jake/Dirk as parsed through Caliborn& #39;s vision.
3) Caliborn also sort of wants to (and this is gross, bear with me) couple with Calliope in some sort of fucked up Cherubfreudian way-> Doc Scratch acts as roleplay rendering of Calliope, with the little suit and a white magnum weapon and liking to talk a lot all echoes of her
3a) (I didn& #39;t come up with this take/insight, I was linked to it in a forum post somewhere that I can& #39;t dig up now but it was really good back then I wish I could remember the source.)
Final addendum: Jake also likes delegating all the hard thinking/logistic work of any situation or risk management to Dirk so he, like Lord English/Caliborn, can just focus on the fun stuff
