So I was browsing theories for the Angles ep and stumbled upon this…
Also, there’s one motif that hasn’t been discussed involving Series 7, and it originated in this episode. The “Caretaker” is seen as an angel who’s fallen from the sky. Looking back on Series 7, we see…
- The Ponds and The Doctor fall from the sky, via a transport corridor, in “Asylum of the Daleks”. (Also, Oswin’s ship, the Alaska, crash landed to the Asylum’s surface.
- The Silurian ship falling towards Earth in “Dinosaurs on a Spaceship”.
- Kahler Jex and his Cyborg fall near “A Town Called Mercy”, and the Cyborg is later referred to as Mercy’s guardian angel.
- The cubes fall from the sky in “The Power of Three”.
- There’s a shot of Amy and Rory falling in “The Angels Take Manhattan”.(source)
