odd/interesting/odd about Holly

[kronette.livejournal.com]

Holly calls them "Dave" and "Arnold," doesn't he? Not "Lister" and "Rimmer," at least not Rimmer. Female Holly in Bodyswap says "All right, Dave." In the pilot, it was 'Everybody's dead, Dave." In "Future Echoes," it's all "Arnold."

So it's just the crew that called each other by their last names, or Holly's informal now that they're the only ones left alive? Just something I've wondered.
