Hello, I am Sarah Jane Smith. I was an investigative journalist and I traveled with the Doctor in his third and fourth incarnations. His tenth and eleventh incarnations came into my life and I had the great joy of helping them save the universe again. But I have to confess my heart almost stopped when I heard Davros' voice ....
In all, I have met nine of the Doctor's incarnations, the First, Second, Third, Fourth, Fifth, Seventh, Eighth, Tenth and Eleventh. Because of this experience with the Doctor(s), I have been entrusted with the task of protecting Earth from hostile extraterrestrials and helping peaceful aliens. And I share these adventures with my son and his friends.
