Continuity

 * The Doctor claims to be a professor from Luna University, a university where River Song was a student and graduate of archaeology. (TV: Closing Time) It was also where Bernice Summerfield lectured in archaeology. In fact, River had attended many of Bernice's lectures. (AUDIO: Lies in Ruins)
 * The Doctor recalls the first discovery of Silurians in the 20th century. (TV: Doctor Who and the Silurians)
 * The Doctor uses the term "Reptilia Sapiens", (AUDIO: Tidal Wave) explaining that "Sea Devil" is an offensive term. (TV: Legend of the Sea Devils)
 * Whilst most meetings between humans and Reptilia Sapiens, be it Silurians or Sea Devils, usually end in war, (TV: Doctor Who and the Silurians, Warriors of the Deep, Legend of the Sea Devils et al), the Doctor encourages both leaders to come to mutually beneficial agreement.
 * The Doctor explains that the Sea Devils and the Silurians were descendents of the dinosaurs long before humans inhabited the planet. (TV: Doctor Who and the Silurians)
 * The Doctor claims to be an expert on all things reptile, including Silurian, Sea Devil and Terileptil as part of that. The Fifth Doctor encountered the Terileptil race in 1666, where they were threatening to release a plague virus on the population of Earth. (TV: The Visitation) In 102, the Eleventh Doctor and River Song would later discover that the Terileptils were members of the Alliance, a group intent on keeping the Doctor locked within the Pandorica to stop him from "destroying the universe". (TV: The Pandorica Opens)
 * The Doctor states that he has been somewhere much colder recently, either a reference to his meeting with Jack Frost and his subsequent trip to Lapland, (AUDIO: Break the Ice) or his recent handful of Christmasses spent with Mandy Litherland's family. (AUDIO: Auld Lang Syne)
 * The Sea Devils have built an underwater city in which to survive. The Eleventh Doctor would later discover an entire subterranean city of Silurians beneath the Welsh village of Cwmtaff. (TV: The Hungry Earth / Cold Blood)
