Howling:The Silence in 2011

Here's something that's been bugging me from The Impossible Astronaught/Day of the Moon. While the Silence were driven from Earth by humanity in 1969, there is a single Silence on a cliff overlooking the Doctor's death/funeral in 2011.

So what they heck is he doing there? He can't be there by accident, as Earth is an incredibly dangerious place for the Silence at that point in time and they wouldn't be just wandering around the desert. If I had to guess there are 2 likely answers:


 * 1) The Silence is on an offical mission and is there to ensure the Docotor's death goes off as planned.


 * 1) The Silence in question is a turncoat who was invited along with everyone else and simply got envelope 5 (which no one else knew existed). Falrinn 03:53, May 14, 2011 (UTC)
