Richard Kingsley Is Royalty

Richard Kingsley, despite living in a cheap apartment and working a minimum wage job at a fast food restaurant, is actually of the royal family.

Supporting evidence

 * His name is Richard Kingsley; keep only the first four letters of each name and you get "Rich King." This subtly suggests that he is destined to become the King of England.
 * Richard implies multiple times that he'd been living with his parents until only a few years prior to The First Daybreak at the earliest, suggesting that both of them are alive and well. However, at the end of the demo, he mentions that Mendax had threatened only to harm his cousins. This is likely because the thought that the manager of a fast food restaurant harming the direct children of the Queen of England was too ludicrous to be taken seriously, so he scaled his threats down.
 * According to Richard at the start of the demo, his father calls him "Master Kingsley." This would be unusual in a common family, but less so in a royal one.
 * Despite obtaining a glock 17 seemingly requiring at least connections to the police, Donovan does not question how Richard got his hands on one for much of the trial. It could be that he's aware of Richard's royal ties.
 * What kind of middle name is "Noslwot" anyway?
