- The Hand
- Ha! Try exterminating Captain Jack and see what happens!
- Captain Cheesecake / Beefcake / "that's enough hugging"
- Daleks speaking German! Near Nuremberg!
- Jackie Tyler, not qualified to drive a TARDIS
- So farewell then, Harriet Jones
- The Osterhagen Key, somewhat implausible
- Rose built all that technology to get across the parallel universes so she could get all wuvvy with the Doctor again
- Wiping Donna's memory
Thing's I'm not sure about:
- Two (and a bit) Doctors
- No Big Reset Button then? Everyone remembers the planets and the darkness?
I wouldn't be surprised if we see Wilf again. Actually, I wouldn't be surprised if we see Donna again at some point in the future, though that will take a bit more explaining.
