Talk:Lacrimosa de Magpyr
My dictionary says lachrymose means tearful, mournful. Possibly she used to be before she turned surly.
Lacrimosa means 'weeping, crying' in Latin. It's a stereotypically pretentious gothic nickname. It suits the vampires' exaggerated style. Also, it makes sense when vampire youth pick mortal names as a part of teenage rebelliousness.
