Dear Upziet,
How many times must I pound this thought into your brain? The Doctor never dies! Even if his body is burned to ashes, NEVER assume he's dead. Even those pixelating robots knew better.
Furthermore, he was extremely passive in this adventure. And don't give me his physical condition as an excuse. Some of our best work has been done with dying people. No, instead he went and focused on saving the lives of his friends. Well, even worse, he wanted to save his murder! The entire outcome makes me sick. A wonderfully witty psychopath surrendering her remaining regenerations to save the very man she murdered.
Don't bother mentioning the alien boy with nightmares. It really didn't do anything besides scaring them.
Sincerely, Screwtape
