It has been a few months since the Tenth Doctor and Rose Tyler went their separate ways; Rose ending up with the human half of the Doctor, whom she loved even though it is not the very Doctor who she has traveled with for a few years. Nevertheless, happily engaged and three months pregnant, Rose and the Doctor now reside in London, within distance of her mother, Jackie Tyler, [And mother-in-law, despite the fact that Jackie is enraged that the Doctor got her daughter pregnant.] and a few friends that they have met during their travels; Donna Noble, River Song, Martha Jones, and Mickey Smith, Rose’s ex-boyfriend who works with Captain Jack Harkness and his team. However, something has been troubling the human Doctor ever since he committed genocide on the Daleks, something that will eventually consume him if he doesn’t figure out who is behind his torture.
