She was my first Companion, the reason I started watching the show, and always one of reasons why I stayed watching. I've seen her episodes so many times, I can probably go word for word even today. And I saw her in person: charming and wonderful to the fans. (Oh those days when we geeks took pride in being able to pronounce Romanadvoratrelundar.)
Thank you, Mary Tamm, for all those wonderful moments.
