Richard and Sinclair are brothers.  They used to sing novelty songs at the Minerva Theatre.  Now they work in Lemon Technology's sales and marketing department.  They're difficult to tell apart.  Kimberly has either managed to figure out how, or else they're too polite to correct her when she gets it wrong. 

Richard is currently going out with a girl named Veronica, while Sinclair is interested in Emily (who for some reason is only interested in Richard).
