Joanna's inception[]
It is interesting to note that Joanna's existence was the result of a conversation between Dorothy Fontana and DeForest Kelly. Fontana mentioned that McCoy should have some sort of family they could run into, and Kelly suggested he may have a daughter. Fontana subsequently had two scripts that originally mentioned Joanna, but both were changed before production. – The preceding unsigned comment was added by 68.161.21.28
