Rarity had managed to get full control over her mind through it over the passage of more time. She had been locking away all the memories of Fancy Pants and made Fleur truly 'hers' over the course of the several months. She would have continued to feed off of her with every sunset. But only after some very close and seducing foreplay. Many were known with the unicorn her return but didn't question the way she lived by then. The tailor still didn't want to be disturbed during the waking hours and came up with the lie that she would spend day in day out in the inspiration room, creating the most fabulous of dresses from her mind to the paper.
