Romanadvoratrelundar/Lalla Ward & Mary Tamm #1: Call me Fred!
I saw this thread is very much needed as it simply was not there before! I'm still in shock.
Be it as may, Romanadvoratrelundar -- Timelady, Four's travel companion through seasons 16 to 18, K9's mistress and later President of Gallifrey (anyone listening to the audiobooks?).
Let's start with discussion about her two incarnations (and the respective actresses, Ms. Ward and Ms. Tamm). Also speculation about future incarnations -- personally I'm still convinced that Lucy Saxon is Romana III, it's the hair.
Come in, let's talk!
