"Flapper or slapper?" *snerk* Oh, Donna...
Loved the running gag with all the different Christie novel titles embedded in the dialogue. I'll have to go back through it again later just to try and catch them all.
Also, throughly enjoyed all the flashbacks during the questioning - especially the Doctor's!
Giving the Doctor a big shock? Personally, I was expecting a knee in the bollocks there. :) Though frankly, waiting till episode 7 for the first kiss between Ten and Donna was longer than I'd have bet at the start of the season.
Loved the gathering of everyone around at the end for Agatha and the Doctor to explain the murders away. Particularly with Donna sitting there going "So, he killed them? Wait, no.. she killed them?"
I was half expecting the footman to be the wasp offspring, but the Rev did fit better. Don't make him angry, you won't like it when he's angry...
Loved the references to previous episodes : Carrionites (still screaming quietly) and the Charles Dickens gag. Was that a Ghost Light shout-out when Roger ended up face-down in the soup?
The hidden Agatha Christie books
"Why didn't they ask--Heavens!" - (Why Didn't They Ask Evans?)
"Well, that's put the Cat Among The Pigeons, no doubt."
"Just a Dead Man's Folly."
"Our Secret Adversary is still out there."
"What is that? N or M?"
"Cards On The Table, woman!"
"Gathered here on this Endless Night..."
"He was Taken At the Flood."
Definitely was a Nemesis reference in there, and I know the Doctor was poisoned by Sparkling Cyanide.
"Murder at the Vicar's rage? Needs work." Hee!
Overall, Donna continues to impress me with getting herself out of quite a few scrapes by herself, though still being completely and utterly still herself - that charades scene in the kitchen was hysterical. Fenella Woolgar as Agatha Christie, on the other hand, was also completely wonderful, showing off humour, timing, emotions and downright cuteness. Like Sally Sparrow last year, I found myself wishing she could come along in the Tardis.
