In 1948 , Lloyd came to Great Britain on the " Windrush " . During the voyage , he met Devina and fell in love .

In 1972 , while working at Brixton station , Lloyd was attacked by the animated corpse of a Hakuai called Moan ' na . Lloyd fell ill and was taken to Kings College Hospital . The bacteria l infection , mutated by Moan ' na ' s biological resequencer , transformed Lloyd into a Hakuai . Lloyd then fled , taking Jess with him . The infection went airborne , but the Twelfth Doctor cured Lloyd by feeding Moan ' na ' s resequencer , keyed to Jess and Devina ' s familial DNA , to Lloyd , curing him . He used the TARDIS ' telepathic circuits to rewrite the DNA of the other infected human s 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 " ) After the Doctor moved himself and the TARDIS into the Collins residence , he and Lloyd talked about his infection . While the Doctor was talking about the " beasties " that threatened Earth , he was attacked by Lloyd ' s cat Tibbsy . Lloyd tried explaining to the Tibbsy that the Doctor was . He told the Doctor that like Lloyd , Tibbsy was always looking out for his family . ( COMIC : " Moving In " ) On Christmas Eve , Maxwell asked Lloyd if he was still getting a bike for Christmas . The following morning , Lloyd opened the front door , where he was met by the entire street , who Devina invited for breakfast as a reminder that they were a community and to remember Carmen , who had died over Christmas 1971 . ( COMIC : " Be Forgot " ) In 1973 , 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 locked 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 . ( COMIC : " Doorway to Hell " )
