Blink ( TV story ) Blink was the tenth episode of series three of " Doctor Who " . It was the first appearance of the Weeping Angel s and was the Doctor - lite episode for this series . Writer Steven Moffat had intended to write a two - parter earlier in the series , but was too busy writing and executive producing . Believing he had " messed everything up " , Moffat offered to " throw [ himself ] onto the grenade of the unpopular episode " , referring to the Doctor - lite concept . In a 2008 interview , he admitted that he had only just started realising that " Blink " was in fact " a really great episode " . Because of its late submission , " Blink " was the quickest piece of writing Moffat had ever done , having gone straight from the second draft with no notes to the script and tone meetings before going into production ten days later . The scriptwriting process took such little time to produce that Moffat claimed that " Blink " was such a " tiniest sliver " of his writing career that he couldn ' t remember making it . Synopsis . In an abandoned house , the Weeping Angel s wait . The only hope to stop them is a young woman named Sally Sparrow and her friend Larry Nightingale . The only catch : the Weeping Angels can move in the blink of an eye . To defeat the ruthless enemy — with only a half of a conversation from the Tenth Doctor as help — the one rule is this : don ' t turn your back , don ' t look away and don ' t blink ! Plot . Young photographer Sally Sparrow breaks into an old house ( Wester Drumlins ) and takes photos of fallen chandeliers and moss growing in fireplaces . Entering a room upstairs , she sees peeling wallpaper and the letters " BE " exposed underneath . She pulls back the corner and finds the message " BEWARE OF THE WEEPING ANGELS " . She tears off more wallpaper , revealing a message telling her to beware of the Weeping Angel s , and telling her to " duck , Sally Sparrow . " It is only when she reveals the words " duck now " that she actually does so , narrowly avoiding a rock that would have hit her head . She looks out the window , from where the rock was thrown , and sees the statue of an angel with its hands covering its eyes . She peels the rest of the wallpaper off to reveal the writer of the message — " Love from the Doctor , 1969 . " Sally appears to return home , looking into her living room ; there are numerous televisions ; they show a man with glasses , although in one screen and young woman is butting into the scene . The man tells the viewer not to turn away , not to look away , and not to blink — " Blink and you ' re dead . " Sally calls her best friend Kathy Nightingale , despite the late hour ; she answers , groggily , but refuses to leave her home . It ' s then revealed that Sally is in " Kathy ' s " home , having been given a key . Annoyed , Kathy gets ready to greet her friend ; however , upon hearing the toilet , Kathy asks if Sally has met her brother , warning her that she ' s about to . Sally turns to the hall to see Kathy ' s naked brother , Larry , who desperately hoped he was wearing pants . Kathy walks in , shouting at Larry to get to bed ; she then notices Sally isn ' t concerned by this , asking her what ' s wrong . The next morning , Kathy and Sally return to the house ; Kathy has a laugh that they are acting like detectives . Sally shows Kathy the message on the wall and the Weeping Angel , but thinks it is now closer to the house than before . Someone rings the doorbell ; Sally answers it , and Kathy waits in the room where the writing on the wall is - " in case of incidents " . Sally answers the door to discover a man who is looking for her . He says that he was told to come to this place on this exact date and time and give Sally Sparrow a letter . As Kathy spies on the conversation from in the room , she fails to notice the Weeping Angel moving whenever it isn ' t in sight ; lowering its hands from its eyes , and creeping into the room and up on Kathy from behind . When Sally asks the man who sent him , he replies that it was his grandmother , Katherine Wainwright , who specified that he explain that before marriage , she was known as Kathy Nightingale . At that moment , the door to the room Kathy is in slams shut . Sally calls to Kathy , which the man assumes is her wondering if he said the right name ; he restates her full name Katherine Constello Nightingale . Sally presumes she has figured out the joke and calls for her friend , but Kathy does not answer . When she goes back into the room where she left her , Kathy has completely vanished , and the Angel is back in its original spot and position outside . Elsewhere , Kathy gets up in a field , and asks a local lad where she is . He replies that she is in Hull , but she refuses to believe it until he shows her the local newspaper , which not only confirms her location but also shows the year to be 1920 . Back at Wester Drumlins , the man has become upset ; he promised to fulfil this task for his grandmother , Kathy Wainwright , who died in 1987 . This persuades Sally to take the letter , who reads it ; this man is indeed Kathy ' s grandson , who swore to fulfil her last request . In anger , Sally flings down the letter and heads upstairs , only to find three more Weeping Angels . One of them has a Yale key in its hand . She takes it and heads out , only to find Kathy ' s grandson leaving with his promise fulfilled . As Sally leaves , she fails to notice the Angels uncovering their eyes and watching her as she takes the key and leaves . In a coffee shop , Sally reads the letter fully , learning Kathy led a full and happy life ( with Ben , the first man she met in Hull ) with a family . She includes photographs of her and her children ( with her daughter named after Sally ) , and grandchildren . Sally reads Kathy ' s joke about living to an exceptionally old age and her request to tell Larry , who works at a local DVD shop , something ; her parents are gone by this time , so he ' s really her only close family . Sally goes to Kathy ' s grave to pay her respects to her dead friend ( having a laugh that Kathy lied to Ben , claiming to have been younger than she was ) , then leaves for the DVD shop . Sally fails to notice one of the Angels from Wester Drumlins spying on her in the graveyard . When Sally gets to the DVD shop , she goes into the back to find Larry . She sees the man with glasses who gave her the blinking warning on a TV . Larry explains that the man is an Easter egg found on seventeen DVDs and no one , not even the manufacturers or the publishers , knows how it got there . As they are talking , the DVD keeps un - pausing itself , and the man with glasses says random phrases , one of which shockingly fits with something Sally commented . In the end , Larry gives her a list of the seventeen DVDs that have the Easter egg on them . She leaves the shop , having gotten an idea from a comment in passing by Larry ' s co - worker ( " Why does nobody ever just go to the police ? " ) about what to do next . Sally goes to the police station , and after mentioning the house ' s name , meets up with DI Billy Shipton . He shows her a collection of cars with something strange in common : all of them were found outside the Wester Drumlins house ( some with their motors still running ) and all of their owners vanished without a trace . He shows her a fake police phone box , with a lock that will not open . Billy charms Sally to give him her mobile number before she leaves . After she leaves , Billy finds the Weeping Angels have appeared in the room with him , surrounding the phone box . While examining them closely , he blinks . Outside , Sally finds the key she took from the Angel ' s hand in her coat pocket . She heads back to the garage to try it out , but Billy and the police box have gone , and the outside door is broken . Someone has broken through it with great force . Billy gets up to see the Doctor and Martha , who tell him he is in 1969 , because of the " touch of an Angel . " The Doctor advises not to go swimming for an hour as time travel without a capsule is disorientating . Martha advises Billy to nod when the Doctor stops for breath . Billy wonder how the Doctor found him ; the Time Lord shows off a modified lunch box , which detects when someone comes from a different time - " and can cook an egg from 20 paces , whether you want it to or not . " Because of this , he actively avoids chickens , as it ' s not pretty when they blow up . The Doctor explains that normally , he would have offered Billy a ride home ; however , someone ' s nicked his motor . After they talk , the Doctor asks Billy to give Sally Sparrow a message , and apologises that it will take " a while " to get the message through . Back in the present , Sally gets a phone call . She goes to visit an old and dying Billy at the hospital . They have a laugh that Billy managed to marry a Sally , who has already passed away . He then passes on the Doctor ' s message - " look at the list " - the list being the DVD list Larry gave her . Billy reveals that he didn ' t stay a cop back in the ' 70s ; he instead got into video publishing . Sally realises that he was the one who put the Easter eggs on the DVDs . He also says that she will understand one day , but that he won ' t ; the Doctor has told him that this is their last meeting , and that he has only as long as the rain stops before he dies . Billy goes to explain that he could have contacted her before tonight , but the Doctor advised him against it as the resulting temporal paradox could have severely damaged the universe . She decides to stay with him until the end . After the rain has stopped , Sally calls Larry . She has realised what the DVDs on " the list " all have in common : they are all owned by her ; specifically they are the only DVDs that she owns , which means that the Easter egg is meant for her . She asks him to bring a portable DVD player to the old house . Larry does so , and brings the DVD with the best sound on the Easter egg . They play it , and see the full message from the Doctor . He makes the same random comments from the video store , but now they fit perfectly into what Larry and Sally are saying . Realising this , Sally thinks he can hear them , but Larry explains that he always says it and that he has got a transcript of the Easter egg with him . As the Doctor gives his message , everything Sally says seems to fit in , so Larry , now very excited , begins to add her words to the transcript . The Doctor mentions that he has a copy of the transcript on his autocue . That is how he knows what she is saying . He warns of creatures from another world , the " Lonely Assassins " , aka the Weeping Angels . They are incredibly fast , and they can send people back in time , which is how he got stuck in 1969 . These aliens have a unique defence mechanism which he calls this a " quantum lock " . ; if any living thing looks at the Angels , they immediately turn to stone until they are no longer looked at . This explains the " weeping " ; they cannot look at each other , since it has the same effect . Since a statue can ' t look away or blink , the Angels who see each other never move again . These Angels feed off the days their victims never had , and now they are looking to get into the TARDIS , which is filled with time energy , which the Angels will feast on for a lifetime , and since Sally has the key , the Angels are after her now . The Doctor is stuck in 1969 , so he is relying on Sally to send the TARDIS back to him . When she asks how , he mentions that he has run out of transcript , but he can guess why : he surmises that the Weeping Angels are closing in , forcing her to flee and so left the transcript unfinished . Indeed , Larry has stopped writing . He says what Sally has already heard ; she must keep her gaze on the Angels ; she mustn ' t turn away , look away , or even blink – the Angels can move with incredible speed when unobserved ; " Blink and you ' re dead . " Once the message has ended , Sally and Larry both realise at the same time that neither is looking at the Weeping Angel anymore . They look up . The Angel is now in the room with them , baring sharp teeth in a savage snarl and outstretching clawed fingers towards them . As a terrified Larry keeps his eyes fixed on the Angel to stop it getting any closer , Sally tells Larry to stay in the room to keep the Angel where it is , while she searches for a way out . As she tries all the doors in the house , only to find the Angels have locked them in while they were watching the Doctor ' s message , Larry is growing increasingly restless and fearful that the other Angels could come up behind him . Larry turns around for a split second , and the Angel moves to right in front of him . Keeping his eyes on it , he slowly backs out of the room . Sally finds an unlocked door to the cellar , and calls out to Larry to give him the news . Larry willingly flees to rejoin with Sally . Larry and Sally descend into the cellar to find a way out . They find the TARDIS , along with the other three Weeping Angels . They head towards the door , keeping their eyes on the Angels . As they get to the TARDIS , the fourth Angel has appeared by the stairs and is pointing at the light . The light starts to flicker , and Sally and Larry realise in horror that the Angel is draining the light so that the Angels will be able to attack in the darkness . With each flicker , the Angels move towards Sally and Larry with their claws out and their teeth showing , as the humans frantically try to unlock the TARDIS door . At the last second , they open it and flee inside and lock the Angels out just in time . As the two look around at the TARDIS interior in amazement , a hologram of the Doctor activates , and says that the TARDIS has detected an authorised control disc , valid for one journey only ; it is the DVD that Larry played for Sally , which is now glowing . But the Angels outside begin shaking the TARDIS on each side , looking for a way in . Larry puts the DVD into the console and the TARDIS begins to dematerialise . But as the TARDIS begins to fade away around them , Sally realises the TARDIS is leaving , but she and Larry are not going with it . She screams at the Doctor to help them , even as the TARDIS fades , leaving them crouching in the middle of the circle of Angels . Sally yells to keep looking at them , but Larry stands up slowly and realises that the Doctor tricked the Angels - they ' ve been left looking staight at each other , freezing them permanently . A year later , Sally and Larry are running the DVD store together but Sally cannot let all that has happened go as she still doesn ' t know how the Doctor got all the information he possessed . Sally is shown to now have everything she recorded ( including the transcript , the photos of the wall and the list of DVDs ) in a folder which she keeps on her at all times . When Larry goes out to get some milk , she sees the Doctor and Martha getting out of a taxi . She rushes over to talk to them , only to find that he doesn ' t recognise her as the events of her past are still in his future . Sally suddenly realises that she is the one who gives the Doctor the information he needs to retrieve the TARDIS and save her from the Weeping Angels . Sally then hands over the folder telling him he ' s going to be transported back to 1969 and he ' ll need to ensure he has it on him when he is . The Doctor is in a rush , still in the middle of another adventure , but asks Sally ' s name and tells her its nice to meet her . Larry returns right at that moment with the milk and can only stare at the Doctor and Martha in stunned amazement . The Doctor is in a hurry and cannot stay , so he and Martha eventually head off to take care of " four things and a lizard " , while Sally clasps Larry ' s hand and goes back into the shop , Sparrow and Nightingale ' s antiquarian books and rare DVDs . However , the scene shifts to montage across the public statuary , punctuated with the Doctor ' s recorded warnings , as though to warn us that there might be other Angels lurking among the statues . . .
