Aeolian ( TV story ) Aeolian marked the midway point in the first series of " K9 " . It was most notable for advancing the romantic story arc present from the initial episode . Significantly , Jorjie finally admitted to Darius that she liked Starkey , preventing Darius from admitting his true feelings for her . The episode left open what impact this would have on Starkey ' s already fractious relationship with Darius or whether Starkey reciprocated Jorjie ' s feelings . Synopsis .

Darius refuses to believe that the storm is being caused by music , but Gryffen insists that music and weather are similar . K9 consults his database and finds the Aeolians , masters of amplification , wiped out over a thousand years ago in the Centaurian Catastrophe . Gryffen pinpoints the source of the sound at the Holy Cross Cathedral . At Department HQ , Drake notes their scientists are baffled , Thames Valley has turned into " Cyclone Valley " and the tornado has destroyed the Royal Albert Hall and Hyde Park . Drake suspects Gryffen , who he says almost single - handedly caused the Great Cataclysm . He decides to arrest Gryffen for being a " mad scientist " . Jorjie , still trapped in her bedroom , desperately tries to reach her dog whistle . K9 warns that Earth is the perfect planet for the Aeolian ' s amplification abilities . Gryffen loads a schematic of the Cathedral for him to analyse . It is the perfect resonating chamber . Gryffen suggests an Aeolian survived .

Darius gets the two syringes Gryffen gave him and uses the red syringe . He comforts Jorjie as she reawakens . Gryffen and June are confused as to why the sound waves are so varied , as the mating call should be consistent like a bird ' s song . The weather briefly returns to normal . Gryffen determines that the Aeolian will feed back on itself and vibrate the planet to dust . Jorjie tells Darius that when the ceiling fell on her , her life flashed before her eyes and she felt she has left many things unsaid . She says there are people she ' s gotten close to recently , a person she saw at the mansion whom she ' s fond of . Darius tells her he ' s had the exact same feeling .

The CCPCs arrive to help . K9 decides they have to go to a tunnel which doesn ' t concentrate the sound . The CCPCs lift the debris off Jorjie . Starkey and K9 arrive in the cathedral , where the Aeolian plays the organ . She tells K9 that she lost her mate in the Centaurian Catastrophe , which left her alone in the universe . The music continues . This sound will smash the Earth like a hammer smashing an egg . When Starkey asks if there ' s any way to stop the feedback loop , she replies it can only be stopped if she is answered by her mate and she fears he is dead . At the house , Gryffen detects an incoming signal from the Orpheus constellation : the Aeolian ' s mate . The female Aeolian has to get the exact sequence right or her husband won ' t recognise her .
