Every good private dick needs a contact at the local police department. Angel lucked out when the gorgeous Kate became his.
Brought up in a law enforcement family, Kate always found herself living in the shadow of her father - a man who just couldn't get used to his little girl being a cop.
When Lockley senior was killed by vampires, Kate's uneasy working relationship with Angel became increasingly strained. She also gained a reputation at work for being more 'out there' than Fox Mulder on a space ship to Alpha Centauri.
German-born Elisabeth Rohm seemed doomed to become Angel's answer to Riley Finn - the new love interest the fans didn't want.
When they realised that Kate wouldn't be Angel's new squeeze, the fans soon warmed to her.
Now starring in Law and Order, Elisabeth's popularity has increased still further. Filming in New York makes it tough for her to schedule further appearances in Angel, but bear with her - she's working on it.
