So, just an interesting theory. It may have been brought up before but what if the reason that the TARDIS doesn't like Clara is because she is the one who blew it up, causing the cracks in the universe?
I know the popular theory is that the Silence did it but it makes sense sort of.

Apparently we're going to find out at Christmas.

Aye yeah so i've heard. Just thought i'd give my view on it before it happened.

I've seen this theory discussed on other spoiler sites. BTW, there is already a thread on this topic: http://forums.digitalspy.co.uk/showthread.php?t=1828121
