While covering for teammate Owen Harper, who was suffering from a serious hangover, (TV: Exit Wounds) Tosh, pretending to be a medic named "Dr Sato", performed an autopsy on the supposed pilot of a spaceship crash inside Albion Hospital. The pilot, (TV: Aliens of London) which Tosh nicknamed the "Space Pig", (TV: Exit Wounds) was not dead, but in shock or hibernation. The creature's x-rays were nothing like she had seen before, and Tosh assumed "that's what aliens looked like". The creature, which was still alive, broke free from the morgue and injured Tosh.
After soldiers shot down the shocked creature, the Ninth Doctor explained to Tosh that it was a ordinary Earth pig and "someone's taken [the] pig, opened up its brain, stuck bits on, then they've strapped it in that ship, made it divebomb". Tosh realised from this that the technology can't have been from Earth, and the aliens were faking aliens. (TV: Aliens of London)
Grob übersetzt: Toshiko springt für Owen Harper ein, weil der einen schweren Kater (oder so hat), spielt Gerichtsmedizinerin und staunt nicht schlecht, als sie das mit dem Raumschiff abgestürzte Alien untersucht, dann erwacht es zum Leben ... und den Rest kennt ihr aus der Folge.
