The point is however that if there is time travel, she has been the 'owner' of Bob and could interact with him similar to the instance in which Thomas interacts with Bob in a short story. Therefore, Murphy could interact, via TT or without, with Bob telling him to fix something. Perhaps, Bob has some sort of dissociative disorder that he isn't even aware of. Murphy is able to speak to him without the other Bob part knowing. We do know that Bob has cut off parts of his personality to create other Bob's so he is very similar to the psychological disorder: dissociative identity disorder. Add to that he adopts the personality of new owners, there is a strong case that he does have a dissociative disorder.
