Brian Williams ( Dinosaurs on a Spaceship ) Brian Williams was the father of Rory Williams , the father - in - law of Amy Pond and paternal grandfather of River Song . When River married the Eleventh Doctor , he became the Doctor ' s grandfather - in - law . Biography . Brian attended Leadworth Primary School ' s nativity play one year in the 1990s when his son was cast as Joseph . He commented that Rory and Amy made a " lovely couple " , which his granddaughter agreed with . ( COMIC : " Imaginary Enemies " ) Brian was not present when the TARDIS dramatically materialised in the middle of his son ' s wedding reception , and was not introduced to the Doctor that evening . ( TV : " The Big Bang " , " Dinosaurs on a Spaceship " ) Brian and the rest of Amy and Rory ' s families and friends were under the belief that the couple honeymooned in Thailand ( TV : " Dinosaurs on a Spaceship " ) when in fact they travelled through space and time aboard the TARDIS ( TV : " The Big Bang " , TV : " A Good Man Goes to War " ) and honeymooned on an interstellar cruise ship ( TV : " A Christmas Carol " ) and on a planet which was on a honeymoon with an asteroid . ( TV : " Death of the Doctor " ) Brian first met the Eleventh Doctor when the TARDIS materialised around him while he was attempting to help Rory and Amy change a ceiling light bulb at their house . The Doctor had taken Rory and Amy along with Queen Nefertiti of Egypt and John Riddell to 2367 to investigate a ship that was headed straight to Earth and would reach it in six hours . Upon entering , they immediately found it contained dinosaur s . The Doctor did not realise that the TARDIS had materialised around Brian and had taken the latter aboard until after the TARDIS landed on the spaceship . While looking at the main engines of the ship , the Doctor , Rory and Brian were taken to Solomon by his robots . Solomon had killed all the Silurian s on this Silurian Ark and forced the Doctor to repair his legs so he could make off with the cargo . Discovering he had a few hours until the ISA launched missiles at the ship and unable to pilot the ark , Solomon took the most valuable thing on the ship identified by his IV system , Nefertiti . The Doctor magnetised the ark , trapping Solomon ' s ship that was inside . The Doctor released it once he put the signal of Silurian Ark inside Solomon ' s ship . The ISA missiles destroyed Solomon . Rory and Brian , who possessed the same gene chain , were able to pilot the Ark to safety with the parallel pilot compartment s . The Doctor returned everyone home , and gave Brian a sense of adventure when he saw the Earth from space . Brian began travelling around the world and sending homemade postcard s back to his son and daughter - in - law . Among the postcards was one from the planet Siluria , to which he had travelled with the Doctor and the dinosaurs aboard the Silurian Ark . ( TV : " Dinosaurs on a Spaceship " ) Brian lived in London , in reasonably close proximity to his son and daughter - in - law ' s home . He watched and recorded the Shakri cubes during their slow invasion of Earth , and started " Brian ' s Log " , describing any changes . During Amy and Rory ' s anniversary , he noted their clothes had been different after they ran into the Doctor and realised they had gone on a trip in the TARDIS . Later , at the time of the cubes ' activation , he helped Rory at the hospital . While searching for medical supplies , two " orderlies " took him aboard the Shakri ship . The Doctor rescued Brian , and Rory , who had followed him on board . He restored the millions of humans whom the cubes had put into cardiac arrest , destroying the ship in doing so . On Brian ' s urging , the Doctor took Amy and Rory back as full - time companions , as travelling with him was a once - in - a - lifetime opportunity . The Doctor invited Brian back to travel again in the TARDIS with his family , but Brian declined . He said that someone had to tend to Amy and Rory ' s plants . ( TV : " The Power of Three " ) Minor references . At some point in his life Brian owned a caravan and parked it at Rory and Amy ' s house . Rory suggested they use it for a road trip to Barry Island , but the Doctor hooked it up to the TARDIS and took it to Florana . ( COMIC : " Summer Wholiday " ) Personality . According to Rory , Brian disliked travelling to other places ; however , following his adventure aboard the Silurian Ark he began travelling quite often and shared his travels through postcards with his son and daughter - in - law . Brian loved his son , Rory , but didn ' t seem to have very much faith in him until their adventure with the Doctor . He liked his daughter - in - law Amy and noted that Rory was a lucky man . During the adventure , Brian bonded with Rory and realised that Amy was as lucky to have him as Rory was to have her . Brian was more confused than frightened when the Doctor took them to a spaceship full of dinosaurs , unable to fully believe that it was really happening . Although he did not fully understand what was going on , Brian did show that he was capable of picking up small details , telling the Doctor that he and Rory could pilot the ship after hearing the Doctor mention something about a gene chain . He also displayed delight about getting the chance to pilot a spaceship , finally opening his mind to the fact that what he was experiencing was really happening and not in his imagination . ( TV : " Dinosaurs on a Spaceship " ) When the Doctor returned to Earth , Brian seemed comfortable in his presence and devoted himself to keeping an eye on the cubes at the Doctor ' s request . He displayed some concern about what happened to the Doctor ' s companion s if they stayed with him for too long , but despite this he encouraged Amy and Rory to continue their travels with the Time Lord . ( TV : " The Power of Three " ) Behind the scenes . " But not them , Brian . Never them . " . In " The Power of Three " , when Brian asked the Doctor what happened to the people who travelled with him , the Doctor explained that some left him , some got left behind , and admitted that some , " not many but some , " died . He then promised Brian , " Never them . " In the very next story ( " The Angels Take Manhattan " ) , Amy and Rory would meet a bitter - sweet fate . Rory was sent back in time by a Weeping Angel , and Amy decided to join him so he wouldn ' t be alone . They lived their lives together in the past and eventually died in their eighties , some time prior to 2012 . It has not been seen on - screen if or how Brian learned of their fate . This was not originally to be the case , however . " P . S . " was envisioned as a live action mini - episode coda to the events of the September 2012 portion of series 7 , particularly " The Angels Take Manhattan " . However , according to its writer , Chris Chibnall , it was cancelled when an actor ' s availability fell through . Its storyboards were then animated , and narration was commissioned from Arthur Darvill . Ultimately the scene was made public by the BBC as a webcast that was uploaded following the broadcast of " The Angels Take Manhattan " . " P . S . " reveals that a week after Rory and Amy left with the Doctor , Brian , having been watering the plants as he said he would in " The Power of Three " , answered a knock at the door to discover an American man in his sixties , who gave Brian a letter and walked in . Brian sat in the lounge and read the letter revealing it was from Rory , explaining that he and Amy are alive and well , but stuck ; they can ' t come back . However , he assures Brian that he and Amy had a wonderful life in New York City , " fifty years before [ Rory ] was born , " and adopted a son , Anthony Brian Williams , who was the man who delivered the letter to Brian . When all was revealed , Brian went to Anthony and welcomed him with a warm embrace . Although available online , this minisode has never been released on DVD or Blu - ray .
