Elisabeth Sladen, AKA Sarah Jane Smith one of Dr. Who's most popular and enduring companions, died last week. I wondered who would be my companion if I were the good Doctor. Not Amy Pond. Cute, plenty of fun, loaded with important destiny, but as naive as a gradeschool girl.
Rose Tyler, maybe. She would die to save the Doctor. More likely Martha Jones. Smart, savvy, and able to wisely take on trouble. Donna Noble? Ultimately, no. Not the brightest, and not likely to make the best choices. She has occasionally a good heart, but less than A-level wisdom.
Comic Relief - Catherine Tate and David Tennant (no Billie Piper in this one)
