"I'm very welcome."
The Doctor went back cleaning the console. He was very pleased that his future self was correct and he turned his normal age again once he was back in his own time stream. Wait a moment. He was remembered something...
A young man with floppy hair and a bowtie.
"Who are you?" The Doctor had asked suspiciously, " Why are you in my head?"
"Oh. I'm you. The 11th Doctor as a matter of fact. I'm here with a message to me. I have to say exactly what I remember hearing me say. Here goes. First, I'm here to help. However, I can't say or do anything I don't remember me doing or saying. I don't want to belgium the universe." He grinned slightly at his own joke then continued, " You get that joke in about ... three regenerations I think."
He chuckled. It is quite funny sometimes how paradoxes resolve.
" What's so funny Doctor?" Peri had returned to the control room from wherever she had been.
"Nothing. Something I once told myself finally making sense." He said with a slight laugh.
"That didn't make much sense Doctor."
He threw a lever. The memory was fading once again.
"I guess not, now where would you like to go next?" On to business like nothing had happened.
