The things the Hive had done to Linsey, beginning when she let herself be tentacle raped, made her easy to hypnotize with the right stimulus. The pleasure techniques Michelle had employed on Linsey were deliberately designed to induce a deep hypnotic trance by sexually stimulating her, making Linsey easy to manipulate and control. This wasn't the first time Linsey had this done to her. After coming out of her trance, Linsey didn't recognize where she was or what she supposed to be doing until the photographer handed her a bottle of baby oil.
