In the Dr Who episode “The Doctor's Daughter”, we see a bunch of young people fighting the Hath. Why is Cobb the only person that is old, considering that the war between Humans and Hath only began a short time ago according to Donna's calculations.

If each person has to be processed and they all are accelerated to be adults, then how did Cobb come to be so old? I don't think this was explained in the episode.

  • You're correct, I don't think it was addressed. Possible hypothesis: there was a fault with the age accelerator when he was cloned - either aging him past prime, or continuing to age him after completion. Or he had a premature aging disease. – Adeptus Jan 31 '18 at 5:53

    "Russell T Davies suggested in the podcast for the episode that, as well as creating a child from a parent, the machines could clone important figures. General Cobb could be the fifth Cobb of that week." – Valorum Jan 31 '18 at 9:51

    I don't think they ever really explored the workings of the cloning machines themselves, but my internal reasoning was that it would accelerate the clones' ages up to the age they were when their original templates were mapped by the machines. So if, as a 20-year-old, you scanned yourself into the machine, it would make clones of 20-year-old you; but if you were 60, it'd make 60-year-old clones. – Vanguard3000 Jan 31 '18 at 15:15
  • @Valorum kind of makes sense... – Pikachun Feb 1 '18 at 0:57

    @Pikachun who's to say she isn't? As a rule, the Doctor is always an exception to a rule. Even the aforementioned one. ;) – Vanguard3000 Feb 1 '18 at 1:14
