Dollhouse

If you had the ability to erase a persona, then with the clean slate, add whatever persona you could design- and you'd shown you could design almost anything- who would you not design?

Topher? Designed. The Watchers? Designed.

If it was me, everyone working at the dollhouse would be designed. Everyone would be wiped, at some point. There'd be wheels within wheels within wheels, as Frank Herbert might say.
