Welcome to Gaia! ::

It's definitely an interesting and intriguing idea (in other words, I think it's good). I'm wondering how it'd happen.

I mean I have an idea. Like I said during the war the Susan and Doctor are reunited I wrote a small portion so far. Susan is looking for the Doctor she is running around worried when she asks the 9th or 8th doctor if she knows him and he says
"One day I shall come back, yes I shall come back, until then there must be no regrets, no tears, no anxieties s(sp) just go forward in all your beliefs and prove to me that I am not mistaken in mine"
She screams and hugs him

and that's it so far

Cool idea, but there's already a fanfiction where Susan is alive on the internet. They're pretty good stories, here's the link. http://rdwf.org.uk/doctorwho/ But that doesn't mean that you shouldn't write yours! And the ones in the link above are not like the idea you wrote down. I wish I actualy had the time, energy, and determination to write good Doctor Who fanfiction.
