Odessa Calvin

Odessa Calvin was the daughter of the scientist, Sean Calvin.

The Seventh Doctor managed to convince Sean not to go through with the plan to take over the world and Sean was eventually forced to use his equipment to save his planet from an alien invasion, resulting in a journalist learning about his original scheme and forcing Sean to go into unofficial exile.

However, the Doctor mused that his real goal was to ensure that Odessa was left with a positive example to follow, the Doctor departing with faith that Calvin's final words to his daughter would help her strive to be better and inspire others to do the same, her father's example helping her to recognise that people could not be defined by their mistakes no matter how great those mistakes were.
