 " Blink " is the third story of the revived series to be adapted for television by the same writer from a piece of their spin @-@ off writing . It follows the " Human Nature " and " The Family of Blood " story arc , which was adapted by Paul Cornell from his 1995 novel Human Nature ; and " Dalek " , which used the basic premise as well as several scenes and lines of dialogue adapted by Robert Shearman from his 2003 audio drama Jubilee . " Blink " is referred to as a " Doctor @-@ Lite " episode because the Doctor and his companion have very little screen time . This allowed two episodes to be filmed simultaneously , a process known as " double banking " . The practice had begun with the 2006 entry " Love & Monsters " , and would continue for episodes such as " Turn Left " , " Midnight " , and " The Girl Who Waited " . Moffat stated that he felt relaxed when he was writing the script for " Blink " , for if it proved to be unpopular , he could blame the " Doctor @-@ lite " structure of the episode . Due to the show 's tight schedule , " Blink " had only one script meeting .
