Not at all! He shares a lot of the same characteristics as him, especially in the guise of Berty from Mary Poppins; if you keep reading you’ll see a lot of references to movies, that one being absolutely no exception. RGB is a blend of a lot of different people, as well as being very obviously his own person, so you’ll doubtless pick up traits from other characters all over the place (which is in itself a part of the story). The only key difference to note between him and Berty, asides from the obvious tv for a head disembodied-jackass situation, is that RGB has what is refereed to as a Received Pronunciation accent. The type of toffy-nosed BBC accent you’d hear from tv announcers in the 60’s.
Not that I don’t love Berty’s… ‘cockney’ accent. It is a unique experience.
The story is journey, so they’ll be constantly changing locations, which will be half explained as we goes along- but as I never state beyond a pair of landscapes where the city at the beginning is I may as well tell you we are currently in Manchester.
