"I can still send you to a differen reality, Jim replied. "You're not leaving this room, ever again." Sharon 4 hissed.

Four identical faces, sad but stern, gazed steadily at Jim. "But you can't keep me here indefinitely," he protested. "And if you let me go, I'll be good, I promise. I do love you really, you know. It's just that I'm weak, and when I get the idea for some fascinating experiment I just can't resist it."

"That's always been your trouble, Jim, hasn't it?" Sharon 2 said. "You just can't resist. That's why we need to keep you here, where you can't do any more harm, to us or to others. Meaning well is no excuse." "But he has a point," Sharon 3 said. "It's not practical to keep him here. This place isn't built to be a prison, and it would need at least two of us to stay with him at all times to ensure that he didn't escape, as he could overpower any one of us on their own. And we want to get on with our lives, not each spend fifty per cent of our lives - and seventy-five per cent of our time awake - guarding Jim."
