That was lovely. I've favourited it because I think it's one to read again: all those little strands. I like your vision of what happens between Rose and Handy after the dimensional curtain closes and they leave the beach - it really is clear throughout the new series that Rose and the Doctor do want different thing. Also, I was never really satisfied with that ending. It was kind of left field, but that's neither here nor there.
I like how you've worked Romana into the story, and E-space, and that one moment where the cloud passes over the sun and Rose realises that she's already dead: tragic, but very real.
And OF COURSE she would travel in a police box! What else?
thanks for sharing!
