The whole DoctorDonna thing started back in Planet of the Ood, where the Ood called the Doctor and Donna DoctorDonna. Blimey, that's a mouthful...
Donna heard heartbeat noises during the finale, but this was all to do with the DoctorDonna thing.
During The Stolen Earth, a woman from the Shadow Proclomation said, "I'm sorry for your loss," to Donna. We now know that this meant Donna's memory loss.
It turns out the bees were following a signal (can't remember it's name and don't have a clue how to spell it)
The thing on Donna's back was a Time Beetle, aiming to change time.
Dalek Caan stated that the Prophecy said that someone will die, or everlasting death for the most faithful companion. This, sort of, turned out to be Donna, or her old self, as the Doctor said that version of Donna was dead.
Rose was able to travel between parallel worlds because they developed technology which allowed them to do so.
At the end of Doomsday, Rose told the Doctor she was pregnant. During Journey's End Jackie told the Doctor her baby was called Tony. She jokingly said it was called Doctor first.
The Osterhagen Key
This key turned out to be something which would detonate a pile of nuclear bombs which would destory the Earth when the suffering of the human race became so great that it couldn't go on anymore.
The Lost Planets
During the series, plenty of planets were going missing. We now know that is was Davros and the Daleks who had taken them.
I think that's everything. However, here are some other points:
- Why did the Ood say to the Doctor, "One day your song will end."
- Captain Jack seemed like he was asking Martha to join Torchwood at the end of the episode Journey's End. Mickey then joined the two, also sparking rumours he'll be joining Torchwood.
- Who is River Song?
- Could Rose and her Doctor possibly have a spin off series? It could always be possible!
- Did Davros and Caan really die, or did they escape with an emergency temporal shift?
- Donna's ring seemed to be shining at one point in the episode Journey's End, was it light or the Master's ring?
