"Be it appearance, memory, personality, behavior mode, or thinking pattern, the sim you've seen... Is no different than the Dr. Mobius I used to know. And the 50000 years spent in the Elysian Realm didn't bring any changes to her. So from the observation data, she can of course call herself the real Mobius, and I have no problem with that. (...) Why deny one for the sake of other? There's no necessary connection between the two. They can both be the real Mobius, or the other way around. The bottom line is there's no clear definition for 'the real Mobius', and everything you say is subjective."
