The Doctor and River Song are on the verge of being sacrificed to the Gods of rain in this Neil Gaiman-scripted Doctor Who mini episode. Naturally the Doctor devises an escape plan—though it’s not necessarily an elegant one.
Over on Gaiman’s Tumblr, he explains that this minisode started as a deleted scene from the episode “The Doctor’s Wife,” and was then drawn by Mark Buckingham as a three-page comic. Gaiman decided to rewrite the scene as a minisode, titled “Rain Gods,” featuring River and the Doctor for the Series 7 box set.
Some people have pointed that the credits say: “by Steven Moffat.” On Tumblr, Gaiman says that credit is erroneous.
