What a fab finale in last night's Doctor Who. I loved it. But today, I was struck by something startling. I was trying to re-tell it to my Mum - the void, the parallel worlds, the "void stuff", the final separation (including that heart-wrenching part when the Doctor and Rose both put their hands on the wall where the breach was) and I was suddenly struck by all the similarities to parts of The Amber Spyglass, the final book in Philip Pullman's His Dark Materials trilogy (fantastic, if you haven't read it. A great story and beautiful prose)
Now it's about four years since I read it and I'm too lazy to crawl over the tip that is the office to check finer details, but this is how I see it.
The Doctor used the 3-D specs to see the "void stuff", which was a bit like energy from the void that attached itself to anyone or anything that had crossed it. The woman (Mary? I think so anyway) used the Amber Spyglass to see lots of gold coloured particles that were invisible to the naked eye - I can't remember if it was coming from the holes between the worlds or disappearing into them, but the holes needed to be sealed, because everytime someone traveled between world it weakened the whole fabric of the worlds. (sounds familiar?)
The Doctor was the only one who could seal the breach forever, but to do so, he had to do it from Earth and therefore needed to separate himself permanently from Rose (okay, she had other ideas, but you know what I mean!) In HDM, Will was the only one who could seal the holes, but he could only do it from his world and had to leave Lyra behind in hers.
After the breach was sealed, the Doctor and Rose each stood on their side of the wall, trying to feel the connection still. Meanwhile, Will and Lyra try to keep their connection alive (to themselves at least) by sitting on the same bench in their own Oxfords.
Am I imagining all this?
Doesn't detract from either Doctor Who or His Dark Materials though - both were utterly brilliant and I sobbed piteously at the end of both of them...
