Donna, our favourite stroppy Londoner, has been having some funny turns recently. As we all know, she's happily married with two kids, but lately she's been having "lost time" and Dr. Moon says everything is fine, and... What? But what about the library of the future, and the people-eating shadows, and River Song and everything? And then, we see a familiar person in Donna's world: Miss Evangelista, one of the Red Shirts killed in the last episode. And she tells Donna that none of this is real.
