As a shear guess, Meghan is an activist, and infiltrated the King and Queen type government, to expose it and end it. Yoko Omo (activist) infiltrated John Lenin, so she or her dreams of a one world country, could get heard thru Lenin’s songs.
This also reminds me of a black and white couple I know. The wife’s big “thing” is an obsession about how badly blacks are treated by whites. So why did she marry a white guy?
Eventually, like slavery, the king and queen thing will probably get fazed out, and Kate is maybe hoping to start the end of it.
