Well, wasn't that something else?
The Doctor thought he was victorious, Adelaide shot herself and he began the slow realisation that death was coming his way. In forty days time, we will see the first part of The End Of Time, the story that will usher out the Tenth Doctor and judging by the trailer, it won't be pleasant.
Friends Reunited: Wilfred Mott (Bernard Cribbins) meets The Doctor (David Tennant) and learns that his hero is going to die. Having Wilfred as the main companion for the finale is a stroke of genius. I can't think of a more deserving candidate. Oh, wait a minute.She Has Returned: Did anyone really think for a second that Donna Noble (Catherine Tate) wouldn't show up in the finale? She's rumoured not to be the only one reappearing but outside of Wilfred, I'm pretty sure her role is rather crucial. If that phone call is anything to go by, then it looks like Donna's getting a trip down memory lane.
