Maybe Liz has already overheard Jasmine making similar mean comments about her, hence the reason for her nominating Jasmine the other day?
Wasn't her reason something to do with her saying Jasmine reminded her of the girls who used to bully her at school?
Jasmine needs to be careful - she may be a stunningly beautiful young woman right now, but if she's not careful she may find herself in a few more years looking far more 'scary' than Liz.
