Sarah Jane Smith was the first assistant I remember. She was my favourite assistant too. I used to have a video of her first adventure. It was a good one with Jon Pertwee facing down a Sontaran warrior who had been transporting scientists back to Medieval times to repair his spaceship. In addition he was supplying the local warlord with firearms. That story also had the Brigidier, who died recently too. Sarah Jane Smith started off as one of those feisty feminists, but soon fell in line. I much preferred her to Leela, the two Romanas and all Peter Davison's assistants. Peri was pretty hot though.
