thelastresort lines for this little ball of crazy while I decide whether to make her a human or vampire? If human, she'll have been there a few years already, addicted to being bitten, and would need a vamp guy who sometimes revels in her crazy and who she's practically obsessed with. Maybe a Joker/Harley-esque feel to them a la Suicide Squad. If vampire, she'll need a sire and others she's sired, plus her favorite human(s) to toy with. She'll be a little bit on the sadomasochistic side either way, if only for shock value and attention.
I've also got two others to plot for: a smartass vampire who enjoys the hunt and sees humans more as objects than people, and an innocent-ish human who was recently brought to the hotel.
