I'm still going with 'current tech only', which means the Sponsors would need someone who really resembled Tori to provide the corpse -- and that still odds-om means a murder. ('I'm not really dead' tends to fall apart under autopsy examination.) The hotel manager did seem to heal quickly, though -- but that could be makeup, identical twin, or a very comprehensive health care plan.
But if it's science as we know it, mind control beyond the most basic techniques is out -- and what's happening is more towards conditioning than hallucination.
No one being all that hurt yet? Behold the power of the script!
(With standard irony: ) Watch it, round eyes.
