Biography
First adventure with the Doctor
Craig placed an advert for a flatmate in a local shop window. The Doctor turned up on his doorstep later that day thanks to a helpful note from Amy Pond in the future. Since Amy was stuck in the TARDIS with no way to land it on her own and the Doctor knew the trouble was in the upstairs flat of Craig's building, he wanted to live there.
The Doctor turned up with a paper bag of cash and no luggage. Craig said he was "weird", but after trying one of the Doctor's impromptu omelets, agreed to let him stay. Craig learned to live with his strange habits and quirks, but was irritated at the Doctor's success at football and his interruption of a moment with Sophie.
Craig defied the Doctor's recommendation not to touch the dry rot on his living room ceiling. It knocked him out but he was saved by the timely intervention by the Doctor. When he woke, Craig learned the Doctor had gone to a planning meeting at his workplace and was working there. He looked in the Doctor's room and found a strange spinning contraption made of trash. After seeing the Doctor talk to a cat about the upstairs flat, he confronted the Doctor on the past three days and his resentment of his popularity, especially with Sophie. The Doctor headbutted Craig to telepathically explain his predicament and gain Craig's help confronting the enemy upstairs. Craig learned about the Doctor's origin on Gallifrey, his previous incarnations, Amy Pond, that the contraption was a scanner, that he had a TARDIS and that the upstairs flat was actually a disguised time ship.
Amy told them someone was upstairs, and they realised it was Sophie. After saving her and learning the ship's intention, the Doctor was chosen as its pilot. Craig realised the ship had refused his help because it needed someone to pilot it away and he wanted to stay. He put his hand on the ship's controls and said what made him want to stay, blurting out his love for Sophie. Sophie told him she loved him too and they kissed.
After their escape from the ship, Craig and Sophie decided to visit Paris and begin a serious relationship. The Doctor tried to leave quietly, but they noticed and stopped him to say goodbye. Craig gave him his keys to the flat, and the Doctor said he would visit them. Having been inside his head, Craig knew the Doctor would never visit them again, but wanted him to keep them as a memento.
After the Doctor left, Craig remembered their time together fondly. He kept a photograph of him on his fridge and spelled out "THE DOCTOR ROCKS" with magnetic letters. (DW: The Lodger)
Return of The Doctor
Some time later, Craig and Sophie had moved and had a child, Alfie. (DW: Closing Time)
When Sophie went on holiday with a friend, Craig was left to take care of their son, despite Craig worrying about his new reponsibilities. (DW: Up All Night) The Doctor came knocking on Craig's door. Craig noticed he was acting strange, but was unable to find out why.
The next day, Craig found the Doctor working in a local shop. Realising that the Doctor was investigating, Craig insisted on helping him. They discovered Cybermen. Craig was almost turned into their Cyber-Controller, but when Alfie began to cry, the upsurge of emotions allowed him to overcome the conversion. The emotional feedback made the Cybermen and their ship explode.
As he and the Doctor parted, Craig gave him a Stetson. When Sophie returned, both were shocked by Alfie's first words: "Doctor Who". (DW: Closing Time)
