Would You Travel With Me? (One shot)

Scarlett Tyler. An ordinary 20 year old working in a shop...

She runs and co-owns a ordinary little shop in downtown London until one day a mysterious stranger shows up and battles a ferocious metal alien droid.

With her shop destroyed and a stranger inviting her to travel all of space and time with him, what is in store for Scarlett?

This is the thrilling tale of how Scarlett Tyler met The Doctor.

Sadly, this is only going to be a one-shot.... I can't think of any more ideas...
