"I think it's time for you to go back to Gallifrey to finish your training as a time lord."
"But why? Remember, they told you I didn't need, that was in my blood"replied Charles to his father, The Ten Doctor.
"Because I want you to be officially a time lord, I want you to pass you exam and get your diploma like everyone in Gallifrey. I don't want to hear the son of The Doctor didn't get his diploma by the official ways. You understand now?"
"Yes, I do! And once I pass the exam and get the diploma, will I go back with you ?"
"I promise, you will, but I also want you to say for a while in Gallifrey, to know each place of the planet, everything. And then, you will be able to come with me as long as you want. But now, let's go back to Gallifrey. I have a old friend to see."
Charles the son of The Doctor and The Queen Mary-A we met in Family Afair, who already knew it was better for him to stop asking question to his father, said good night and left him alone in the main room of the TARDIS. Charles, was half Time Lord by his father and half prince of France by his mother Marie-Antoinette.
The Doctor went to bed, it was late and the journey to Gallifrey will be really long.
