There's a new edition of RTD's "The Writer's Tale" coming out in a couple of days.
http://www.sfx.co.uk/page/sfx?entry=20_things_we_learnt_from I think one of the more insteresting things is that the Time Lady was the Doctor's mother. It makes me awwwwwww. We've never heard about her before, but she's his mum and tries to protect him until the end. *sniffs*
So the people who pointed out that the Doctor looked at Sylvia after Wilf asked - good eyes! I had to go back and watch it myself, since I didn't really remember that. But yeah. The Doctor pointedly looks at Sylvia after Wilf asks, then changes the subject when he turns his attention to Donna.
Also, both Mickey and Martha were planned for Torchwood's CoE, but were written out at the last minute due to conflicts. So those rumors were true. I'd still like to see Martha and Mickey on Torchwood's S4, so this gives me some hope. I guess it'll depend on the actors. But CoE probably would have given us the backstory to "OMG MARRIED!!!" we were missing.
