Ok, a really dumb question: If Charles becomes King, doesn't she become something?

The law of title is very simple in this regard. A woman who marries a man of higher rank automatically aquires the female form of his title. Therefore if nothing else changes on their marriage she will become Princess of Wales, Duchess of Cornwall &c.&c.; then on his accession to the throne she would become Queen.

The problem is that most people are not terribly happy about this (I'm not overly keen, but neither am I terribly bothered myself), and therefore I think it likely that she will be given an alternate title - which can be done by specific intervention of the Queen.

I see. Could Queen Elizabeth take her son out of the line of succession and make William the heir?

Actually, she is going to become HRH the Duchess of Cornwall (in deference to Princess Diana, they ie; the palace, are not naming her Princess of Wales) when or if, Charles ever ascends to the throne, she will become the Princess Consort (Like Prince Albert was to Queen Victoria)
