That is a great story there, and OMG i have the same thing with my Bonehilda!
I dont have two, but all of a sudden my male sims are getting calls from "Bonehilda" wanting to go on a date :O
I rejected the date, so i have no clue if there is a live Bonehilda in my town, but im so curious now!
I lock my gates to everyone but my household and that keeps her in the property as well. But i noticed lately since i moved my sims that the new one is fully up herself and looks at herself all the time. She even approached my vampire sim who she obviously likes cause its him she calls for the date, flirted, he knocked her back then she goes and checks herself out again. she also does everything else but once she finishes she is at that mirror posing like its no ones business LOL
