Jess Collins Jessica " Jess " Collins was an art history student who grew up in Brixton , London . Jess lived in Brixton with her parents Lloyd and Devina , who met on the " Windrush " while emigrating to Great Britain , and her brother Maxwell . ( COMIC : " The Pestilent Heart " ) In 1972 , she went with her boyfriend Dave to find out if the " Highgate Vampire " of Highgate Cemetery was real . Jess discovered a vampire creature , known as a Corvid had killed Dave by draining his psychic essence . Upon realising the cult leader Gabriel Rosewood had used his own followers as bait to easily manipulate so he could gain the Corvids ' power , she called him sick , and pushed Rosewood into a tombstone to allow her and the Twelfth Doctor to escape . When the Doctor banished the Corvids to the Time Vortex , Clara Oswald insisted that the memory of Dave would help Jess when she went back to her normal life . ( COMIC : " The Highgate Horror " ) Jess met the Doctor again six months later , and helped him to investigate an alien distress signal which was coming from Brixton tube station , as she knew the area . The Doctor was unable to go pass the ticket barriers without money , so he snuck into the station at night . Jess followed him to the station , where Lloyd worked , and they saw the animated corpse of a Hakuai attack Lloyd . The Doctor electrocuted the creature with the tracks , and had Lloyd taken to Kings College Hospital . Returning to the Hakuai corpse , the Doctor found a telepathic node on it . Activating the node , the Doctor and Jess found a recording , which revealed the creature was a criminal on the run from his own people called Moan ' na who rewrote his DNA to hide among human ity on Earth . When the Doctor discovered Moan ' na was near a plague pit , he and Jess rushed to Lloyd in the hospital , where Lloyd ' s mysterious bacterial infection turned him into a Hakuai . Lloyd then fled , taking Jess with him . When the infection went airborne , Jess and Devina tried getting through to Lloyd , but were unsuccessful . However , the Doctor keyed Moan ' na ' s biological resequencer to Jess and Devina ' s familial DNA , and fed it to Lloyd to cure him of the infection . He used the TARDIS ' telepathic circuits to rewrite the DNA of the other infected humans to return them to normal , but this caused the TARDIS to overload , trapping the Doctor in 1972 . With nowhere for the Doctor to go , Devina offered him to stay with the Collins family . ( COMIC : " The Pestilent Heart " ) A few days later , while Jess was reading an Escher book , the Doctor told Jess about how art had to be experienced in person and not . He told Jess about how he wished he could take Jess to when he met Monet , Renoir , and Boucher , and when had his portrait done by the cubist artist Picasso . While trying to light Jess ' book with his sonic screwdriver , the sonic ran out of power , and the Doctor was unable to use the TARDIS to recharge it . With no TARDIS to leave 1972 in , the Doctor instead offered to show Jess the universe through the art she was studying . ( COMIC : " Moving In " ) The Doctor took Jess and Maxwell to the National Gallery to show them a Constable painting , when an alien creature was released by alien hunters from Kolothos ( where hunting was outlawed ) and the hunters sent hounds to chase it into the gallery . The Doctor , Jess and Maxwell followed the creature outside into Trafalgar Square , and witnessed the hunter Skadi murder a policeman . The Doctor used a dog whistle to incapacitate the hounds , and when Skadi ' s husband Broteas killed another policeman , the Doctor knocked him out by pulling his electric whip into a fountain . Skadi murdered the small creature she was hunting , and she and her son Tarquel kidnapped Jess and Maxwell aboard her ship . While Broteas was arrested on Earth , Jess learnt on board the ship that Skadi kept a whole menagerie of the rarest and most exotic creatures ready for them to hunt for sport . When the Doctor offered himself and Broteas to Skadi in exchange for Jess , Maxwell , and the menagerie , and Skadi leaving Earth right after , Skadi broke her promise , and had her hounds chase the Doctor and Jess . The Doctor knocked the hounds down using a reprogrammed metal horse belonging to Broteas , and Jess did the same to Skadi after she tried to kill the Doctor . When Skadi then threatened Jess ' life , Maxwell appeared to threaten Tarquel , forcing Skadi to drop her sword and subsequently be arrested by DCI Jack Hayes . Tarquel then took Skadi and Broteas out of Hayes ' custody to bring them to justice on Kolothos for their killings . ( COMIC : " Bloodsport " ) While Jess and the Doctor were delivering Christmas card s on 23 December , they saw Walter from across the street behaving oddly and then slamming the door . The Doctor kept an eye on Walter ' s house all night . The following day , Christmas Eve , the Doctor saw Walter throw a snowglobe through his window . The Doctor , Jess and Devina broke in to help Walter , but no - one else was in the house but Walter . Through the guilt of losing his mother Carmen in 1971 and being left alone for too long , Walter imagined the fictional character Obadiah Grimm murdering the Doctor , Jess and Devina with the touch of his hand . Walter was taken away in an ambulance to treat his mental illness . After Devina returned from the hospital , she worked with Jess to prepare a breakfast on Christmas morning , where the whole street was invited as a reminder that they were a community and to remember Carmen . ( COMIC : " Be Forgot " ) In 1973 , Jess wanted to join Hayes and the Doctor at the station when he was invited to come down , but Hayes insisted only the Doctor could come . Later , the Collins family were knocked out by Katya Dabrowski and her men , and taken to an apartment in central London . They were greeted by , who told them the Doctor was a threat to them and a powerful and deceitful alien . Ensuring the Collins family that the Doctor would never hurt them again , the Master used the artron energy in their body as a means of opening a portal to a time lock ed dimension , which they were also sent to . Jess , Devina and Lloyd were separated from Maxwell . A tentacle in the dimension caused Jess ' leg to necrotise , making it harder for her to walk . While trying to escape from alien creatures across a ridge , Jess and Devina saw them age Lloyd to dust . Maxwell reunited with Jess , and a being called Kiadine , who the Time Lord s had imprisoned on this world , reversed what had happened to Lloyd . The Master found Kiadine , and was offered his temporal powers , and the Doctor and the Master fought with each other over the power of the chronon storm , when the Collins family pulled the Doctor back , standing together against the Master . The Master attacked them , and this blast was repelled with the same artron energy in the bodies of the Collins family that had brought the Master to the dimension . The temporal effects on Jess and Maxwell were also reversed . The Master survived this attack and left , and with no - one left to keep time in check , the Doctor and the Collins family evacuated . After Gabriel ' s funeral , the Doctor said goodbye to the Collins family and left in a fully repaired TARDIS , believing he had outstayed his welcome . Thirty years later , Jess was showing a group of students Constable ' s painting " The Hay Wain " , when she saw the Doctor and the TARDIS in the picture . ( COMIC : " Doorway to Hell " )
