So, the Silence was able to turn Melody Pond into a time lady due to the fact that she was conceived in the TARDIS, and then they raised her to be an assassin. But also, the TARDIS she was conceived in was partially possessed by a giant omnicidal space dog.
This probably isn't true, but it would be really funny if some of Sutehk got into her, and her assassin training was actually teaching her to be LESS trigger-happy. Like, her first word were "I SHALL BRING DESTRUCTION AND DEATH TO ALL LIVING THINGS" and the Silence had to be like "no, sweetie, just the Doctor."
