The Doctor had always had a hard life, even as a child. He had been the unwanted second son born of the flesh and never measuring up to his loomed older brother. No matter what he did, it was never right so he would hide in the barn at night and cry. He liked to think that his mother loved him even as his father called him a disgrace. He was told that he would never get in to the academy unless he learned to shape up. Still, somehow he had made it into the academy, disgracing his family once again as he turned and ran from the untempered schism. He thought things would get better once he started school, but he was wrong. His professor's used him constantly as an example about why children of the flesh were wrong and should be looked down upon. He barely survived the academy and if it hadn't been for his friend Koschei, he knew that he would have taken his own life. Koschei saved him from the ridicule, protecting him even when his own family turned their backs. Koschei had been his first love, his first time, and his first heartbreak. Even though they eventually grew apart, he knew that a part of him would always love him.
After leaving the academy, he was forced into an arranged marriage by his father. He never loved his wife, but gave her everything she asked for, including three loomed sons. He tried to be a good father to his sons, but even they were taught to look down upon him. Standing at the untempered schism, they were inspired. They saw great things for themselves. Soon, they saw what a poor Time Lord their father really was, especially when he left their mother. He was ridiculed for being selfish but with no children in the home, he didn't see a point in staying where he was unhappy anymore. His youngest son eventually forgave him and gave him his granddaughter Susan, who loved him dearly. He tried to make up for his failings as a father with her. He loved her, protected her, and eventually ran from Gallifrey with her. He even did what he thought was right, leaving her with David to find the love he never had.
He hated the planet that he was born on, but still, he returned time and time again. Sometimes it was at the Council bidding. Other times it was just to visit his mother or one of his sons. Even if he hated the planet, he found comfort walking in the red grass beneath the twin suns or staring up at the familiar stars at night. That was why it nearly killed him when he had to burn the planet. He never knew why he was unlucky enough to survive. To walk on alone with a new face in a universe that he no longer felt that he belonged in. With his first face, he just tried to survive but it was within his next body that he finally found happiness.
Laying on his back, he stared at the ceiling as he listened to the steady snoring of his lover and companion. Jack had given him back a piece of happiness that he didn't think that he deserved. He had hurt Jack by not telling him about his daughter, then again by being forced to carry his second daughter. Jack forgave him for the pain of not knowing being told about Kui'la until after her fifth birthday but there was no forgiveness needed for Imogen. He loved the little girl like his own, never blaming the Doctor for siring her with the Master. They even married shortly after her and Grey's birth.
The Doctor was thankful for Jack as he didn't think that he would have made it through these last three years without Jack's support because while he had two healthy children his daughter was another story. She had been born prematurely thanks to the abuse the Doctor caused to his body. She had to stay in the medi-bay for the first few months of her life as she grew. Yet, even after being released, she constantly had to return due to illness. Even though they were technically a few days apart, she was behind Grey developmentally. She learned to walk late, talk late and was behind in her coordination. She even had to have surgery before her second birthday. He had sat with Jack terrified they were going to lose their daughter but she was strong and now at just past two and a half, she was slowly catching up to her siblings.
Unable to sleep, he pulled himself out of bed being careful not to disturb his husband. Making his way out of the room, he first went into Kui'la's room. She was sleeping peacefully tucked beneath her purple blankets with her doll Sophie in her arm. The Doctor had worried that she would have nightmares after her initiation ceremony but thankfully she had been sleeping peacefully. Closing the door again, he looked in on Grey next. He wasn't surprised to see that Grey wasn't in his bed and going to Imogen's room, he found her sleeping next to her. The two of them were almost inseparable growing up almost like twins. He couldn't help the smile that crossed his face upon seeing them. They had a hard few years, but things were finally starting to look up.
