 Pris and Racheal are the same android 

I'm afraid this is going to be quite a useless comment at the moment, because I don't have the book in front of me to quote from.

However I came to this Wikipedia article originally to see if it could help me decide whether Pris and Rosen are in fact the same android (not just the same model).  The article makes no mention whatsoever of something that has really been puzzling me.

Why do I think that Racheal and Pris might be one and the same:

- Pris originally introduces herself as Racheal Rosen when meeting JR Isidore and then changes her mind and calls herself Pris (if Pris is simply using her name for cover how do she know her?)
- Deckard says that Racheal and Pris have the same eyes (in fact the only difference he notes are clothes)
- We hear no more from Racheal after Pris has been killed (I'm assuming there she killed the goat before she went over to the conapt building)
- When Pris runs towards Deckard before she dies her last words are along the lines of ""For all we meant to each other.""  Surely they don't know each other at all; Pris and Deckard have never met if she is someone else.
-  Pris also runs towards him from outside the conapt as opposed to inside it - i.e. she has been following Deckard as Racheal and not holed up with the rest of the Andys
- Racheal is really distraught in the hotel room when she finds out about Pris being the last android, it would make much more sense for her fear to be because it is her rather than the same android model.  It is only when she offers to kill it herself that she calms down.  But then she would - she had just claimed to kill herself (i.e. bluff Pris' death or possibly commit suicide).

Admittedly there's a couple of snags.  If she is Racheal then she is working for the Rosen corporation, so why is she hiding with the runaways?  Unless she ""ran away"" from the corporation after Deckard originally tested her.  

Anyway I'd like to add something to the article - obviously nothing conclusive, but just acknowledge the possibility.  But if anyone would like to blow a huge smoking hole in my theory that I haven't thought of, then I won't (and it would stop me putting more time into trying to figure this one out too, which would be handy).
