The introduction of the beautiful Nicole Wallace/Elizabeth Hitchens in the form of Olivia D'Abo. Surely she's too young and innocent to be behind the brutal murders of university personnel?
It's a well-written character, though she is a tad far fetched in her abilities to seduce just about anyone or anything. The story itself doesn't seem to matter that much, and I was slightly confused actually as to why all this murder was necessary. It's all about getting Nicole and Bobby at loggerheads, and the two actors do play nicely off each other, though Ms D'Abo's talents are not extensive by any means. I think we've fallen again for the 'speaks with an English accent therefore can play an evil b*tch' syndrome.
As an Englishman, I have to say I have never ever heard anyone use the 'wouldn't butter your parsnips' phrase, but it's a goodie and I wouldn't be surprised if it passed into the language eventually!
