Rachel Dawes and Alternate Dimensions
In light of
It wasn't my
I did
So, because recent events have neccessitated that I fix the portal to an alternate universe that I keep in the basement of my lab or die, I thought now would be a decent time to ramble about alternate dimensions.
To the best of my knowledge, the Rachel Dawes that was tossed into an alternate dimension was herself from an alternate dimension. We know that the Rachel Dawes of our dimension was killed by the Joker (and became a zombie, but that's another story). The non-zombie Rachel Dawes that was pregnant with Harvey Dent's child seems to have lived an identical life to that of the Rachel from this dimension. (Bruce Wayne has confirmed that her childhood memories match up with his). The key difference between our world and her own seems to be what happened when the Joker and/or the mob took Rachel and Harvey hostage.
In our world, Rachel was killed and Harvey became the loveable, half-burned psychopath we know today. In Rachel's world, she was saved, and Harvey was killed. From then on, she wasn't able to provide much detail, as she was taken to the hospital and her next clear memory is waking up in this dimension. I've got no idea how she ended up in our dimension. (I've also got no idea what's going on with there being two Harveys. I'm a scientist, people, not omniscient.)
There are 52 known alternate universes, and many, many more that we don't know about. That doesn't even take into account things like alternate timelines caused by time travel. (Don't bother obsessing over whether the dimension we live in is actually the correct one, or if we are in fact some flawed version of a perfect world, or if there is such a thing as a perfect world etc. Those sorts of thoughts lead to madness and covering your walls in equations scribbled with Magic Markers. Trust me on this one.)
These alternate dimensions seem to function based on how ironic they are in relation to all the rest of the dimensions. Morals are reversed, up is down, black is white. For example, there is probably a dimension in which we are all prostitutes, aside from Harvey, who is actually a devout priest. I sincerely hope I have not sent Rachel there.
The point of all this is that I need one of you to volunteer to follow Harvey into the alternate dimension, since God knows he can't go alone.
