1. We are now in the Medusa Cascade where the Doctor closed a rift (apparently around the age of 90, 'just a child').
2. We have now met the Shadow Proclamation... and they had no clue who the Doctor was. Anyone else laugh their asses off at that? He's been mentioning them since "Rose" and they've never even heard of him.
3. Bad Wolf may have climaxed in "Turn Left" (if so, it was big enough that I'm okay with it), but we may get more on it.
4. Rose was talking to 'Control' -- her universe's Torchwood, maybe? Mickey, perhaps?
5. The missing planets were being used to create a machine ("The Crucible" -- reminds me of the Doctor talking about something called the "cruciform").
6. The missing bees were the key to reaching the Medusa Cascade - Donna was the one to remember that.
7. Just missed: Jack arrived seconds too late to save the Doctor from getting shot by the Dalek.
8. Dalek Caan went back into the Time War (which is supposed to be 'temporally-locked' -- the way that Pompeii was 'fixed'?) and saved Davros, who built a new Dalek army.
9. Donna Noble is called 'something new' by the woman at the Shadow Proclamation -- the Doctor was called that by the Headmaster (ASH) in "School Reunion".
10. Did not get a complete clarification on what Rose meant by 'the darkness'. Just the planet skipping off or something else?
10. Location, location, location: Martha is at home with her mother and that key. Sarah Jane is on the road and has met up with some Daleks. Luke is tucked away at home with Mr. Smith. Wilf and Sylvia are at home. Gwen and Ianto are facing off Daleks in the Cardiff Hub. The Doctor, Donna, Rose, and Jack are in the TARDIS.
11. Oh, and the Doctor's just begun a regeneration cycle, plus mad Dalek Caan is saying that the Doctor's "most faithful companion" will have "everlasting death" and he's been right so far.
Anything else?
ETA: 12. Hand in a jar, as mentioned by
boniblithe. Because it's still in the console room and there has to be a reason for that.
