Dear Sarah,

I've regenerated again. Don't worry, I wasn't alone. My newest companions were there with me. Two young women are traveling with me. Their names are Tegan Jovanka and Nyssa.

Tegan is from Heathrow, Australia. She's brash and headstrong to say the least. She and I have a tendency to argue, most of the time she's complaining about my lack of skill in piloting the TARDIS. Don't worry, I take no real offense to it, she doesn't know me or the Old Girl that well. I hope that time will teach her that the TARDIS has a mind of her own. I came to have her aboard at the end of my last life. She stepped in my blue box when she thought that it was a real police box. Tegan does care about me, I may be oblivious to some things, but I'm not blind, and I know that she worries about when I'm in trouble.

I acquired Nyssa in my previous life as well. She is kind and smart with an open mind. Adric and I first met her on her home world of Traken. Unfortunately the Master, with the help of the Daleks, destroyed the planet. Now she travels with Tegan and me. I quite enjoy having her around and she is a good friend to Tegan.

I know that you are wondering what happened to Adric. He tried to stop a ship controlled by Cybermen from crashing that would have wiped out all life on Earth. He thought he knew how, but even if he was able to gain access to the ships computer it was too late. The ship exploded and we lost Adric, and the ship became the meteor that killed the dinosaurs. Tegan, Nyssa and I were devastated. They wanted me to go back and rescue him, and I would have if it were possible.

They now sit in his room mourning the loss. I know you're probably thinking I'm a fool for not trying to comfort them, but I'm afraid I wouldn't be much of a comfort. I haven't lost anyone that I'd grown to like in this way since my first life and I'm not taking this well. Once again I find myself in the library thinking of you. I want to believe that you would understand why I can't save Adric. You know me and I explained some of the laws of time to you which means you know I mean it when I say I wish saving him was an option but it simply isn't.

I long for your company if only for a familiar shoulder to cry on and a knowing hand to hold. You are my best friend and I need you right now Sarah Jane, but I doubt the TARDIS would take me to you on the first try.

I hope that you have someone to go to in times like this. I'm sure Harry, Benton, or Alistair would be willing to help you in my absence. They are good guys and they'd take care of you, I know they would, but maybe you've found someone else. I hope you're not waiting for me to show up and whisk you away again. I want you to have the full life that you deserve, and if you ever need another woman to talk to look up Liz Shaw or Jo Grant, I'm sure Alistair can get you their numbers if you asked.

I miss you Sarah, never think that I've forgotten about you, because I never will as long as I live. Now if you'll excuse me, I think I should take my own advice, or perhaps it's your advice, and comfort Nyssa and Tegan what I can.

Your Best Friend the Doctor
