Doctor Who: Cold Blood *SPOILERS*

While reading a recent review on Behind the Sofa, I stumbled across an interesting theory about the crack in time and space that has been almost too prominent in the latest season of Doctor Who. Stuart Ivan Burns seems to think that the crack in time and space was created by the TARDIS, that the Doctor's time traveling is finally taking its tole and tearing a hole in each of the locations that he travels to. This could be why the crack has appeared in each episode, many of the episodes featuring a peek of it as the TARDIS takes off. My only question is what of the crack in Amy's room when she was a little girl? It doesn't appear that the Doctor had been there before... then again, wibbly wobbly timey wimey. Also, what of that chunk of the TARDIS found within the crack - suggesting perhaps that an explosion or crash of the TARDIS created this crack. The idea of the Doctor without the TARDIS is mind blowing, and frankly something I hope I never have to see. Who knows what will come in the next few episodes. I've been really enjoying the new season, as well as Matt Smith, who is brilliant. Unfortunately this last episode has thrown me through a loop. The bit with Rory was odd and seemed unnecessary. We'll see what comes next week.
