Doctor Who: the seventh doctor: a long see yah later

The doctor and Ace were talking he mentioned his son the janitor and Ace being curious asked "does the Master have a child?" The doctor replied " Yes him and my son had the same falling apart" he looked down sadly "he took the title of the breaker"described as red haired with a pencil mustache and beard dark green eyes sort of tall six foot zero, dressed like a hipster and a detective all in one" and my son took the title of the janitor." Ace wondered thinking 'i think I get it but not entirely'. This conversation happened after their conversation after the Master had killed her love interest and close friends. the doctor understanding how she felt said" if you no longer wish to accompany me on my travels I'd understand why." Ace replied " thank you professor, tell you what I'll keep defending the earth in my own way, don't think this is a good bye my friend just think of it as a long I'll see yah later, okay?" The doctor replied " see you later ace."
