So, stuff on this page might be a bit surprising. People have assumed in the past that Seb's upper class, but that's not actually the case. I'd describe him more as 'particularly affluent and fancy middle class' or neuveau riche. Sure, maybe they may as well be upper class as far as many of the people back home are concerned, but they have no connections to any actual nobility.

A good example of what I mean might be the opening scene of 'Corpse Bride.' Though Seb's family are much better at hiding their origins than Victor's.
