A Good Man Goes to War
In "A Good Man Goes to War" (2011), it is revealed that the daughter of Amy Pond and Rory Williams, Melody Pond (who later goes by her transliterated name "River Song"), has been born with Time Lord-like genetic traits. An old acquaintance of the Doctor's, Madame Vastra, reminds the Doctor that the Time Lord race developed due to their billions of years' exposure to the time vortex. The Doctor then recalls that Rory and Amy had spent their wedding night in the TARDIS; therefore it is theorised by Vastra that River's conception mirrored that of the Time Lords' genesis and therefore she herself developed Time Lord genetic characteristics.
