While not the noblest Romana of them all, and even that I personally liked Romana II better.. I did appreciate how Tamm played the role (was written) much closer to an equal of the Doctor, as opposed to Lalla Ward's version that generally came off as more of a companion/assistant.
Can't say I know her from anything else, but her Romana was a formidable woman.
I just finished watching the Key to time the other day. Last night or the night before Lise and I were talking about Lalla Ward and how weird it was the she was Astrid in the Key to time, and then Romana afterwards.
Not to threadjack, but did you know that Lalla Ward married Tom Baker, and then after divorcing him, later married Richard Dawkins?
His daughter wasn't dead, Al's death changed things in the future, so now she's home and his flash forward won't happen. That's my guess. The idea of vigilantes knowing they're going to die and causing mayhem is interesting and one I never considered.
