File for the shadows?

edited November 2012 in The Walking Dead
So, everyone, me included, has been wondering who those shadows are and everyone is creating their own theories. Now, as a PS3 player, I can't look into game files, but PC players can. If someone found out what the stranger looked like, why can't someone see if the shadows were new models or if they're Christa and Omid or maybe just placeholder? Then at least a few questions will be put to rest.
