In a bit of extreme thrift-store luck, I stumbled upon a vintage dress that is extremely similar to Liz Shaw's red dress in The Silurians - but green. So this is a sort of alternate-universe Liz. No, not the one from Inferno - an alternate alternate universe.:)
Dear Liz: Reversed the TARDIS' polarity a bit too far, I'm afraid. Gone to get some equipment - look after her while I'm gone, there's a good girl. The Doctor
Certainly, Doctor, anytime, Doctor, whatever you say, Doctor!
Bigger on the inside, huh?
I bet no one would call me 'good girl' at Cambridge.
