Series 4 Episode 11: Turn Left

Summary:

Although it seems that she is more interested in Donna's past and suddenly a strange creature jumps onto Donna's back and changes everything.

The defenders of the Earth die one after the other, while they try to save the people on Earth from alien attacks. Every time an event like this happens a strange blonde woman appears in Donna's life and she seems to know her. When the darkness comes and the stars go out, Donna decides to help her and travels back in time to stop her younger self from turning right at the crossing. Only then she sees that there is only one possibility to change the fate of the world. Will she be able to save the world and give the Doctor the message of the mysterious woman?

"Turn Left" is the first part of the big finale of series four. Compared to the episode "Midnight" this is a Doctor-light episode where we don't see much of the Doctor but everything is about Donna and her decisions in life. I think this is a great episode and it shows what Donna means for the Doctor and how she has changed his life. Without her, he wouldn't have survived the attack of the Racnoss and the Earth would be in big trouble without him. The Doctor doesn't feel so important sometimes because he is just one man but the things he does change many lifes. It is strange that Donna feels so worthless but she is really one of the most important persons on Earth because one of her decisions has changed everything. It's really good to see Rose again and the next two episodes will be big.

But that's not dying, 'cause a better world is gonna take its place – the Doctor's world. And I'm still alive. That's right, isn't it? I don't die. If I change things, then I don't die. That's… that's right, isn't it?
