Why would it?

"You mean the fucking?" Claire asks matter of factly "Why would that bother me? It's just sex and there's nothing wrong with ****."

Suddenly everything becomes clear to James. She was still affected by the mind control. Even though the device was no longer operating the commands he'd given her remained etched in her brain. The compulsive swearing, the casual nudity, the incestuous lust for her son, were all still in place presumably until he used the device to change them.

He laughs in relief. The possibility that he'd have to keep controlling her every second had been a real concern. Now he knows she won't run screaming into the street if he makes the slightest slip he can relax and get back to having fun.
