15 Doctor Who Mistakes That Nobody Will Ever Be OK With

7. The Doctor Meets His Daughter... And Then Forgets About The Whole Thing

Most of the time, the Doctor drops out of the sky, saves the day and manages to leave the ensuing drama pretty much unscathed. Every now and then, though, something happens that possesses the power to change the entire legacy of the Universe's coveted defender as we know it. The Doctor's Daughter was not one of those times. It really should've been, though, since it introduced our titular Time Lord to a member of his actual family. If you were to ask him about it these days, though, he'd probably dismiss the suggestion that he once encountered his daughter after she was artificially created in a progenation machine using a sample of his DNA. He wouldn't just be in denial about the situation, either. He has genuinely forgotten. Unfortunately, the rest of us haven't. In the Doctor's defence, he does think Jenny's dead, but viewers saw her springing back to life at the end of the episode before commandeering a space shuttle to embark on her own timey-wimey adventures. She's definitely her father's daughter in that regard... even if her father has forgotten!
