Dear Sweetie, I know how you must be feeling. I have been staying with mum and dad in New York. Been watching my adopted little brother grow up. You would have loved him. They miss you Honey, they will never forget you. And by the time you get this short letter as I still followed the rules of spoilers. I know you would have moved on again as normal with someone new. I shall see you again soon my love, very soon. Love Professor River Song. P.S. I would keep a close eye on that Clara girl if I was you xxx.
