A fine list. I'm looking forward to Jamie (more so since I just watched The Two Doctors, which has him in it.)

But I have never seen any Leela episodes and the only Nyssa/Tegan/Adric episode I remember is Castrovalva. I really need to do a rewatch!
I had never heard anything particularly compelling about Leela and then I watched her and was like she's so amazing?!?!?!? Why didn't fandom tell me?!!??! What is wrong with everybody?!?!?! (Romana kind of suffered the opposite fate. I think if I wasn't expecting her I'd have been more thrilled about her, but she has the thankless task of living up to her reputation.)
