From Left to Right: Elizabeth with a different mother Elizabeth didn't get a chance to change after killing Fitzroy 'Hero' Elizabeth (though she doesn't have the bird or the cage around her neck... odd) Elizabeth from an even more religious Columbia? aka Nun Elizabeth Elizabeth who lost her jacket? Elizabeth who didn't kill Fitzroy?
Perhaps the Columbia from the demo version is a different Columbia? As in, it was the first "version" of Columbia to be created, before the Columbia that we see in the game? Therefore, it would be a literal "demo Columbia", if that makes sense XD
doesn't quite explain why Elizabeth's physical characteristics are different, and technically it wouldn't be the 'first' since time is quite relative, and differs from certain perspectives. Is, Was, Will be... 'if we could perceive time as it truly existed, grammar professors would have no reason to get out of bed.'
Well, it could still be an alternate version of Columbia, not necessarily the "first", just the first that people saw. This is actually a reasonable explanation given Demo Elizabeth's appearance at the end of the game.
Well she as a slightly different facial structure and... not to be too crude but... if'n ya look about 12 inches lower you'll notice another not-so-slight difference, which can't be explained by much else but genetics... and game designers...
if they were then how and why would elizabeth have them? being locked in the tower her whole life was an essential part. it's far more likely she either has different heritage or simply an alternate balance in her genetics.
