Isadore has been with Delilah since the 1970's when Delilah introduced hereself to the posh Englishwoman at Club 54. The two entered into an agreed fluidic arrangement - as it were - and within none too long Isadore found herself in the constant company and employ of Delilah. She knows that if she were to ever want to become vampire, Delilah would not hesitate as she has more than once proven herself, but for now Isadore enjoys her heartbeat just where and how it is.

If any vampire ever wants for anything at the Whip, Isadore is always there to tend to their every whim and make sure that every desire is fulfilled - whether it just be a quick meal, companionship for the night, or something a little harder below stairs.
