The Master knocks four times, he also makes every one else knock. So the plot leads us to believe the Master will be the one to kill the Doctor. However it turned out to be Donna's grandfather, Wilfred Mott. Stuck inside a chamber that's about to be flooded with radiation, he knocked four times to get the Doctor's attention. Realising the prophecy was about to come true, the Doctor got into the connected chamber so that Wilfred could exit, and takes the lethal burst himself.
the master does NOT kill the doctor it's someone who's close like wilf
Knock, knock. who's there. doctor. doctor who. you just said it.
The obvious answer is the return of the Master because the drumming he heard is four knocks, but David Tennant and Julie Gardner said on the Planet of the Dead commentary is not what we think it is, Julie also said when we figure it out it will break our hearts. Just as the doctor believes he's safe at the end of 'The End of Time', he hears four knocks. Wilfred Mott, Donna's grandfather, is stuck in a booth that's about to be flooded with lethal radiation. It is he who knocks four times, and the Doctor, being who he has, entered the booth next to it to allow Wilfred to leave. The Doctor receives the fatal dose of radiation, which, after he visits his old companions, causes him to regenerate.
