The universes have collided. Everyone had someone or more than one. Sam, Dean, The Master, Moriarty, The Doctor, Sherlock and John all lived in the Tardis and their homes. They helped each other. One day they were in Cardiff to refuel the Tardis.

A knock came on the door. The Doctor, The Master, and Sherlock all heard it. Everyone else was in their rooms or eating. The Doctor went and opened the door. There was a baby, slightly taller than average, but average weight. The Doctor blocked most of the view of outside for the other men. He picked up the child with an expression of confusion on his face. The child had a Tardis blue blanket. When he picked the child up, he felt the note on the bottom. He read it as he closed the Tardis doors and slowly made his way back over to them. The other men were slightly confused when he turned around, revealing the child. He handed the note to Sherlock, The Doctor's face lighting up with a slight amount of joy and cooed the child softly. Sherlock flipped the note over and read it, The Master reading it over his shoulder.

Hello! This child is one of yours, whether you like it or not. It doesn't have a name, and needs formula when it becomes hungry. You should be able to tell when it is. Try not to get her killed. Oh, and the Tardis won't be able to help you with its identification. Nothing will be able to.

The Doctor could now be heard talking to it softly. It fell asleep quickly in his arms. He walked over to them when they were done reading. Sherlock did an once-over. "It's a girl," is the only thing he said quietly. His deduction wasn't working with the young girl, as she hadn't developed yet. The Doctor looked at the girl what as obviously a fond smile. The Tardis made a nursery for her as he did, knowing she was going to stay.
