I looked up some Bernard theories online and found an interesting one on lost-tv.com
Bernard Rose= Candyman?
I did a boolean search but couldn't turn up that anyone has associated Bernard and Rose with Bernard Rose who wrote the screenplay Candyman, based on Clive Barker's classic horror story.
In Everyone Hates Hugo, Rose saved her candy bar for Bernard, said he had a mouthful of sweet teeth, so I think it's a solid connection. If so, it foreshadows a sinister aspect for one or both characters. The character Candyman was all nice and genteel on the surface but full of rage underneath...
Here's a synopsis (from dvdmaniacs.net) for those who don't know the story.
There's no way to this day I'd EVER say candyman 5 times in a row, even when not looking into a mirror. Scared the bejesus out of me.
Structured around the idea of urban legends and ghost stories, the film gets tremendous mileage out of its setting of urban blight and decay and also manages to work on a the level of socio-political commentary. The ghoulish but seductive figure of Candyman - a variation of sorts on the legend of "Bloody Mary," who can be summoned by calling his name five times while looking into a mirror - arises out of the context of racial discrimination and bigotry in the United States. A well educated descendant of his slave ancestors, "Candyman" was tortured to death by irrational zealots for daring to fall in love with a white woman during the time of the Civil War. With such a backstory, it is possible to see Candyman in a more sympathetic light than, say, Freddy Kruger or Michael Myers, though he remains a formidably frightening presence.
