The Sapling The Sapling was a sapling of the Planting whose development was interfered with by the Scream . Infused with some of the memories of the Eleventh Doctor and Alice Obiefune , the Sapling renounced his destiny as an organic super - virus capable of genocide and instead tried to follow the example set by his " progenitors " : the Doctor and Alice . The Sapling accompanied the Doctor and Alice in their adventures through time and space . During this time , they were followed by the Scream . Biography . Creation . After the Planting seeded itself in a desert planet and replaced all indigenous life with a forest of itself , it created the Sapling with the intention of sending the Sapling to a different planet to do just the same . However , the Scream captured the Sapling in a Memory Engine Machine during its formation . The Scream planned to feed the Sapling with the memories of several long - lived individuals and then use the large amounts of memory energies to merge himself with the Sapling and become part of the sentient ecosystem of an entire planet . The Scream ' s plan was fairly successful up until the end . ( COMIC : " The Scream " ) He managed to feed the Sapling the full memories of a Nebulon and a Rockra , ( COMIC : " Remembrance " ) and some of the memories of the Eleventh Doctor and Alice Obiefune . While the Sapling was absorbing the memories of the Doctor and Alice , the Scream came inside the Memory Machine to merge with it . The process was disrupted when Alice caused the Doctor ' s TARDIS to materialise around the machine . The TARDIS saw that the Scream was dangerous and deposited him outside , leaving the Sapling to grow into a sentient child - like being inside the Memory Machine . ( COMIC : " The Scream " ) Adventures with the Doctor and Alice . After the Doctor and Alice escaped the Scream and briefly reunited with John Jones and the Entity , they returned to the TARDIS and met the Sapling for the first time . Having many of their memories , the Sapling was already intimately familiar with their lives . Due to his nature as a biological weapon capable of genocide , the Sapling asked the Doctor to destroy him , but the Doctor refused . The Doctor and Alice instead took on the Sapling as a companion . ( COMIC : " The Scream " ) The first place that the Sapling visited with the Doctor and Alice was Hackney in the early 21st century to pop in to Alice Obiefune ' s flat . However , they discovered that the Wayfarer had landed on Earth in 1968 and was sucking up the planet ' s time , destroying the barriers between years . Allying with many versions of Kushak , the Doctor , Alice , and the Sapling journeyed from the 21st century to 1968 in a double decker bus . The Sapling used the sonic screwdriver to vibrate the wall surrounding 1968 errected by the Sixty - Eighters , creating a hole . When the Wayfarer prepared to drain the Doctor and Alice of their time , the Sapling did the only thing he could think of to stop the Wayfarer : he began seeding himself into Earth , setting in motion the irreversible biological processes which could replace all life on a planet with forest . However , after the Wayfarer was killed by the Sapling , time was restored to Earth and all events involving the Wayfarer were rendered as having taken place in a temporal anomaly , meaning that they were undone . ( COMIC : " The Tragical History Tour " ) The Doctor took Alice and the Sapling to Plex ' s planet , where they found its inhabitants to be at war with each other . In the ruins of Plex ' s laboratory , the Sapling extended the length of his arms to grab Plex ' s biodata nodule for the Doctor . The Doctor used the nodule to restore Plex ' s memory to one of the clones of Plex , elevating the clone to be a god among his people who would lead them into a new period of peace . ( COMIC : " The Promise " ) During a game of chess with Alice in the TARDIS , the Sapling ' s mind was touched by Ood Sigma ; Sigma channelled a message to the Doctor through the Sapling : " Bring them home . Share the Song . " The channeling put the Sapling into mental lockdown , rendering him unconscious . The Doctor and Alice left the Sapling to recover in the TARDIS while they investigated why the Devil ' s Eye still used Ood as slaves . When the Doctor lowered the shielding of the Devil ' s Eye , Alice put the psychic paper and Jonni Halburton ' s data - slice onto the Sapling ' s forehead , using his unconscious body as a conduit between Ood Sigma and the Ood of the Devil ' s Eye . The Sapling then woke up . While visiting the Ood Sphere with the Doctor and Alice , the Sapling built a Fourth Doctor snowman . ( COMIC : " Time of the Ood " ) Shortly after leaving the Ood Sphere , the Doctor parked his TARDIS in the Antrozenus Zone to get some time to talk with the Sapling one - on - one about the " arboreal - eruption - slash - sacrifice - yourself - slash - almost - kill - everyone thing " the Sapling did to defeat the Wayfarer . The Sapling compared what he did to the sacrifice the Doctor made to end the Last Great Time War . Their conversation was interrupted when a Xerxes Memory Ark drifted near the TARDIS . The Sapling , Alice , and the Doctor boarded the Ark and repelled an infestation of Thrake . ( COMIC : " The Memory Feast " ) The TARDIS trio went on a " shopping trip " to a European village in 1189 which involved them meeting an " old friend " of the Doctor who tried to kill the trio with a legion of archer s . During this adventure , the Sapling accidentally became a well - known figure in the village ' s history , inspiring them to create a statue of him in the village green . Shortly afterwards , they revisited the village circa Alice ' s home era and spent an afternoon at the Village Green Festival . Festival - goers assumed that the Sapling was wearing a costume to imitate the statue . However , even this trip was not without a malign alien influence : a Krovian tried to steal some of the Sapling ' s memories with a Memory Trap , but instead transferred all the memories it had already stolen into the Sapling ' s mind . This initially went unnoticed , but the Sapling came to realise that he could remember elements of the lives of other people at the festival which they themselves had forgotten . The Doctor tracked down the Krovian and destroyed the Memory Trap , removing the memories from the Sapling ' s mind and returning them to their rightful owners . ( COMIC : " Fooled " )
