Darius , Starkey and Jorjie spend a very spooky night at the Gryffen mansion . Plot . As a storm rages outside , Darius and K9 play chess against Starkey and Jorjie , and lose . Jorjie gets a call from her mother who wants her home , but agrees to let her stay . Something shatters upstairs . Gryffen sends Starkey to investigate . The STM activates . While upstairs investigating the sound , Starkey sees a boy outside of his bedroom window for a split second . Starkey is visibly shaken when returning to the others and tells them what he saw . When asked by Gryffen to describe the boy , he tells Gryffen he was a " skinny blonde boy around seven or eight . " Gryffen runs to look . The others doubt what Starkey saw . Jorjie wonders why Gryffen ran off . Gryffen returns to say the storm is intensifying over the Channel . Later , Starkey is reading poetry to Jorjie and Darius . Darius tells them years ago Gryffen and his family went on holiday and they were taken from him . As the storm grows louder Jorjie predicts her mother will be calling again , which she does . When Drake asks who she ' s talking to , she hangs up , surprising Jorjie as that ' s her " trick " . They hear scary giggling and Starkey suggests they investigate . Darius , obviously frightened , is the last to get up . As they leave , he closes the door . The giggling is heard again as the STM powers up . Gryffen suddenly hears a voice calling his name . As Starkey , Jorjie and K9 look around , they spot a boy and an equally odd - looking girl . K9 scans them and finds no signs of life . K9 says that the boy and girl are " non - corporeal entities " . They vanish . K9 tells Starkey and Jorjie to go while he stands guard . They spot the girl , who runs , and then the boy , who also runs away , both giggling . As Jorjie searches , Darius appears , startling her . Starkey , while searching , asks why K9 stays when he could go through the STM to some random place . K9 tells him that he stays for the same reason Starkey does , they are needed where they are . Starkey again spots the boy , who runs away . K9 detects nothing . As Darius and Jorjie go on , Darius grabs hold of a hand . Darius thinks it is Jorjie ' s hand and says that it is " tiny " and " freezing " . Jorjie says she ' s not holding his hand . Darius sees he has some strange slime on his hand . As Starkey tries to find the boy , a mysterious hand grabs him . It ' s Darius scaring him . Jorjie is with him . They find the recording of Gryffen ' s family . K9 is annoyed at them ignoring him , while Darius , Jorjie and Starkey watch the recording . Starkey and Jorjie recognise Gryffen ' s son and daughter as the children they saw . Darius doesn ' t believe it , saying they are Gryffen ' s children , Jacob and Mina . He says it ' s the last video taken of them . As the storm strikes again , K9 tells the kids to stop being so scared at the flashes . Darius recognises the voice of Eleanor , Gryffen ' s wife . They see the children again . Darius recognises them with a shock . K9 realises they only exist as light ; Starkey reasons that if they are dead , they can ' t harm him . The children charge up energy and fire on Starkey , Darius and Jorjie , knocking them unconscious . K9 fires on them , but his photon beam has no effect , merely passing through them . K9 thinks they can only affect carbon - based life , but they disrupt his circuits , knocking him out as well . Eleanor suddenly appears to Gryffen . She says he cannot touch her . She is too fragile . She tells him his children must complete a task before they join him to make him eternally happy . Darius and Jorjie are trapped on tables near the STM , which is absorbing energy . As Darius calls out for K9 , he wakes up , locked in a closet with Starkey . Starkey fails to unlock the door with his " jimmy key " , which is covered in slime . K9 tells Starkey he needs to power his photon burst before trying to blow through the door . Darius and Jorjie call out to Gryffen . Gryffen tries to remember Starkey and K9 but fails . Gryffen goes into the STM room and tells the children to stop playing . When Jorjie and Darius call him , he asks who they are . Gryffen is in a trance . They try to wake him . K9 suggests to Starkey that with his attempts to retrieve them , Gryffen has warped space - time into their shapes . K9 blasts the door . They go to the STM room , where K9 tells Starkey to go round the STM vortex while he distracts the children . Darius and Jorjie try to snap Gryffen out of it , but he is mesmerised by Eleanor . K9 ' s energy is depleted and he is disabled by the children . Starkey tries to stop Darius and Jorjie from being pulled into the vortex . K9 reactivates and warns Gryffen they are merely " echoes " of his family and Jorjie tells him that for them to fully materialise , they must absorb life force . K9 tells Starkey to get to Gryffen as he is the closest thing he has to a son . Eleanor tries to silence him , but he persists . Darius and Jorjie try to help Starkey convince him as well . Starkey tells Gryffen that his family wouldn ' t want to harm people . This lets Gryffen see what they are . Eleanor refuses to accept this , but as the storm passes , she realises she and the children aren ' t wanted and they leave . Jorjie gets a call from June , who says she will pick her up . When Starkey asks Gryffen if he will be okay , he says that he will be as he was . The team cheer themselves up by joking around . Story notes . Ratings . " to be added " Myths .
