I'd seen her name on a call sheet for so many years and been called Jo so many times. If people said Jo in the street, I used to turn round because I was so used to being called Jo for five years on Spooks. You do get so used to being called something. Often, it was someone calling their young son... but sometimes it was people calling after me because they recognised me from the show. So, it was a big deal when it happened and it was quite an emotional end.
