The Second Doctor, Jamie, and Zoe

Wendy Padbury (Zoe) is the most prolific Second Doctor companion, after Jamie, so this section has the most stories. She provides more of a contrast with Jamie, being from the future, and a mathematical genius (a fact she doesn’t hesitate to point out). Her intelligence puts her on the Doctor’s level at times, which causes friction with Jamie, but they generally value each other’s friendship.
