But there is another alternative. What if the Chell from Portal 2 comes from a universe where Portal 1 was consistent with Portal 2? Where in Portal 1 the cubes and the cube droppers were different, and the bts scenes were considerably different?

What if we - who play the game and assume control of the protagonists - have taken part in some dimension crossing between games?

Additionally, I'm not convinced the multiverse stuff can really be considered canon...

Frankly, invoking the multiverse to explain the same thing seems a little unnecessary!

Technically there is an infinite amount of universes for every possible solution and ways the universe was began, therefore GLaDOS would not just be in 'Earth Prime'.

But GLaDOS is Caroline, and in another universe, Caroline is Glocbar. So what is Glocbar as an AI?

at this entire thread, and people who think about shit like this.

Yeah, I agree... Over thinking things like this isn't appealing at all.

What if Chell is from another dimension? Wow, you just opened up a ton of new explanations there. What if Wheatly is from another dimension? What if Aperture is the equivalence of Black Mesa in another dimension. What if teletubbies rule the universe in that specific dimension? No one can tell...

Your theory doesn't really solve anything, it just blows a big stupid hole in an otherwise functional story...
