Since this is an entirely mental plane, how does it affect characters like Rubedo and Albedo, who share a body but are distinct entities inside their mental worlds? As it's been canonly established that characters like that can interact in a mental landscape, would they be independent (essentially resulting in two part comments whenever they're together) or would they still be stuck with what they're used to their situation in the waking world being and thus still have to play musical chairs or resort to telepathy to hold a three way conversation?
