Nightvisiting ( TV story ) Nightvisiting was the third episode of the first series of " Class " . It featured the first onscreen appearance of Tanya ' s brothers and her father , Jasper . Synopsis . London is infiltrated by an eerie alien with the ability to morph into the shape of lost loved ones . Tanya has an unexpected visitor come to her window in the dead of night — and she ' s not the only one , as Ram and Miss Quill face their own startling visitors . Confronted with these emotional encounters , the team must overcome the persuasion of this strange new threat and battle through the streets to stop Tanya from being lost forever . Plot . On the two - year anniversary of Tanya ' s father ' s death , she is visited by a creature resembling him in her bedroom . Although at first doubting that it is really occurring ( believing she is hallucinating ) , the creature seems to have legitimate memories of their time together and appears to be real . The creature attempts to persuade her to take his hand , which he claims will relieve her of her grief . Meanwhile , Miss Quill is visited by a similar creature which claims to be her sister . Although Quill is sceptical of this , the creature offers her a gun and states that taking it will allow her to use weapons once again . At the same time , Charlie and Matteusz have sex and confess their love for one another . Ram also receives a " nightvisit " from his late girlfriend Rachel while video calling with April . Both Ram and April leave their houses in fear and meet outside . While trying to work out what the " nightvisits " are , April reveals that her father attempted to kill himself by driving his car off a bridge when she was 8 , while both her and her mother were in the car ( which is what caused her mother ' s paralysis ) . The creature with Quill eventually reveals that the " nightvisitors " are an organism called the Lankin that feasts on the grief of people and kills them in the process . Quill destroys her branch of the Lankin by making Charlie stab it with a screwdriver . She then claims that she knew the Lankin was a fake from the beginning , as " no one insults the memory of [ her ] sister by making her nice . " Quill , Charlie and Matteusz then decide to help the others defeat the Lankin . Ram and April find a series of tentacles stretching across London that they believe to be the Lankin leading out of Coal Hill and they notice that one tentacle is leading to Tanya ' s flat . They follow it to attempt to warn her . Meanwhile , Tanya is still struggling to believe that the Lankin is her father . As time passes , the Lankin appears to become more aggressive and forceful , which only strengthens Tanya ' s belief that he is not real . Ram and April arrive and warn her not to take the Lankin ' s hand . Tanya seemingly ignores them and grasps the Lankin . However , the Lankin is unable to feed off her grief as she feels more anger towards her father for leaving her than she does grief for losing him . Eventually , the Lankin is poisoned by Tanya ' s anger but not weakened enough . To destroy the Lankin threat , Quill steals a bus and rams the tentacles , breaking them and causing the Lankin to withdraw back into the Rift . Charlie announces that Matteusz will be living with him and Quill , and April and Ram bond over the time they have spent together . Story notes . Ratings . " to be added " Filming locations .
