Kazran Sardick

Kazran Sardick was the son of Elliot Sardick.

Early life
Kazran first met the Doctor on Christmas Eve when he was 12 years old. His father had hit him across the face when he found out Kazran was trying to find out about the fish that roamed Sardicktown at night when the fog came.

Kazran explained his wish to "meet" a fish as everyone else had. The Doctor and Kazran lured a small sky fish to Kazran's bedroom until a sky shark came, ate the fish and half the Doctor's Sonic screwdriver and then trapped the Doctor and Kazran in Kazran's wardrobe. The Sonic screwdriver in the shark's belly began to kill the shark and Kazran led the Doctor down to the basement, where his father kept members of his clients' families in cryogenic suspension as "security".

Kazran removed a young woman named Abigail Pettigrew from a cryonic chamber. Then the other half of the Doctor's sonic screwdriver began to bleep. The Doctor and Kazran realised that the shark was awake again and that the two halves of the screwdriver were trying to find each other; one half was in the Doctor's possession, but the other half inside the shark. Kazran and the Doctor hid from the shark until they heard a voice singing the Christmas hymn In the Bleak Mid Winter.

They realised it was Abigail singing and that she was soothing the shark. They placed the shark in the Cryonic chamber, taking Abigail with them in the TARDIS. They returned the shark to the clouds and then returned Abigail to her chamber.

Christmas Eve travels
Before her chamber closed Kazran announced that the Doctor would visit every Christmas eve. After this, Kazran would go on a adventure every Christmas Eve with the Doctor and Abigail. They went to various locations across Earth. During that period, he began to develop a relationship with Abigail, and one night they kissed. Abigail returned to her chamber every midnight, much to Kazran's dislike.

Eventually she revealed that being frozen was keeping her alive and if she was taken out again she would have only one day to live, so Kazran put a stop to the three's Christmas Eves together without telling the Doctor the reason.

Realising something was wrong; the Doctor left him what was left of his screwdriver to call him whenever he needed him. Kazran bluntly told him that he would never need him.

Later life
Heartbroken over his loss of Abigail, Kazran eventually fell under his father's influence, becoming bitter, and caring little for the lives of others. He controlled the cloud bank with a machine he and his father developed. One night, the Doctor returned, asking him to set his machine so that a spaceliner carrying Amy and Rory could land or they would crash. Kazran refused.

He sent the Doctor away and sat down but suddenly a projector began to play, projecting a video of a younger Kazran recording a diary on a laptop. The video showed Kazran's father, Elliot Sardick, hitting him after he had talked about the fish. The older Kazran, remembering this, began to cry. Then the Doctor walked in and told him to let the liner land. Kazran refused and the Doctor warned him that, whatever happened that night, he brought it upon himself. The Doctor returned to the TARDIS and suddenly appeared in the background of the video still being projected onto the wall of the room.

In the video, the younger Kazran met the Doctor and they started their adventures together. After watching the video, the elder Kazran walked over to a chest and opened it, revealing pictures of the Doctor, himself and Abigail on their adventures. Kazran went down to the basement to see Abigail in her cryonic state, but encountered a hologram of people singing Christmas carols. A hologram of Amy Pond walked forward, introducing herself as the Ghost of Christmas Present and told him that these were the people on the spaceliner. She asked him to change his mind but he refused. He was suddenly transported to the crashing spaceliner and saw the terror taking place. He returned to the basement, but the Doctor was there saying that he was now the Ghost Of Christmas Future. Kazran turned to see his younger self standing there. Kazran stormed over to his younger self and prepared to hit the boy. His younger self thought that older Kazran was his father and burst into tears. Older Kazran, realising what he had done, hugged his younger self and said sorry. They both wept.

Kazran agreed to save the people on the space liner but the Isomorphic controls did not respond and the Doctor realised that this was because he had changed Kazran's lifeline too much. The controls had been made for the cold, bitter and cruel person that Kazran used to be. Then they remembered that Abigail's singing would cause a delta wave pattern vibration of the ice crystals in the air.

Kazran was unwilling to release her; unable to choose what day should be their last together. She was released and told him "Christmas day". Outside, Abigail sang into the other half on the Sonic Screwdriver and the fog cleared. The cloud bank opened resulting in snowfall. The ship was able to land successfully and the passengers - including Amy and Rory - were saved. The Doctor and younger Kazran left in the TARDIS, revealing the sleigh that they harnessed up to the shark many years ago in one of their adventures. Older Kazran and Abigail flew off into the distance in the sleigh being pulled by the shark. (DW: A Christmas Carol)
