The UK's most reliable and dependable news source, The Sun, has apparently leaked the plot of the cliffhanger storyline that will make the 7/6 split of next year's run of Doctor Who.
The Sun claims that Karen Gillan is leaving the show, and that the storyline for the cliffhanger centers around the death of companion Amy Pond. While it may be a mid-season cliffhanger, Gillan has stated that she'll be with Doctor Who for some time yet. As long as Amy's husband Rory is fine, I'll somehow manage to carry on.
As with any news from The Sun, take this one with a planet-killing asteroid sized garin of salt (Wait ... wasn't that a Doctor Who plot long ago?).
