Just curious, but suppose someone (we can use the Queen as our example since you mention her) pushes their consciousness into a clone. What is being left behind as a place marker for their consciousness to return once they are done?
Also, what is to stop another traveler from hijacking the vacant body as the person who was inhabiting it is now focusing on a clone body?
Original body is the anchor theyd snap back near instantly. Like avatar towards the end when he starts choking in the atmosphere in real body and wakes up. Consciousness is not tranferred when using cloning. It is actually only being transmitted. Its like losing skype connection. Bodynatching is different. Nothing can inhabit your body unless they physically drone or chip you. In clones basically All they have is the ability put you into a vehicle that they can mess with you while you are in it. They can even kill you remotely not by killing you in clones but by applying constant overwhelming pain to the clone which in real life can make you have a heart attack or a brain aneurysm.
Bobysnatching may be different, when it is PERMANENT. But to say "Nothing can inhabit your body unless they physically drone or chip into you"- that part I'm going to have to disagree with.
Blackout while drunk- classic case of SOMETHING ELSE coming in & inhabiting your body for a short time. And this is something I have personally witnessed in people. Also there are cases of Possession.
