"Shane's speaking to her, she can hear him but she is unable to do anything else but watch and listen." Currently I have Shane injecting the girl with snake venom but that was just a place holder until I can come up with something more believable. I need something that paralyzes a person and possibly prevents them from screaming for help but doesn't hinder them from seeing or hearing. They are left to see themselves died and can't do anything about it. I have another scene where someone is tied up and gagged, so I don't want to repeat myself in this murder but his MO is leaving his victims consciously aware of their pending doom (with no ability to escape).
