Zoe, played by Wendy Padbury, was a great companion for the Doctor, practical and intelligent, she was a great asset to him in many ways.  Her interaction with Jamie was always fun and the chemistry between the three of them was always a joy to watch.  I created Zoe in her jumpsuit and managed to find out that it was a metallicy dark blue in colour.  When we gave Wendy her little character she said that the blue of the jumpsuit was perfect and she loved her mini me. Zoe was the Second Doctors companion from 1968 to 1969
