The Doctor stood pointing Wilf's pistol at Rassilon, the President of the Time Lords. The Master stood behind The Doctor watching. The Doctor's face was covered in cuts and bruises after falling through the glass dome on the mansion. Behind the president there were two people standing in a weeping position. One of them took their hands down from their face to reveal a woman.
The Doctor felt a pang of sadness when he saw her. She felt the same, and a single tear ran down her cheek as she remembered her child.
She remembered when he ran through the streets of the Time Lord's citadel, a young boy with brown hair. She was so proud of him, a smart boy, one of the best in his class. She remembered living with him in their home. She remembered his friend that was now his enemy.
The Doctor remembered the same memories. He remembered his mother, the most loving woman he had ever met. He remembered her flowing hair as they played in the house and when she read him stories in bed. He wished that he could've saved her, which made the sadness worse.
He wanted to scream 'mum.' She wanted to scream 'son.' They wanted to embrace and run. They wanted to leave everything behind, all this conflict. But they both knew that was a luxury they could never have.
The Doctor suddenly turned back to The Master.
"Get out of the way."
