I particularly like these lines for them:
The potential you'll be,
That you'll never see (Rose thinking it about Ten2, how he'll never see that he is and could be as great as he once was as a full Time Lord, maybe even better)
And I'll make you okay
And Drive the away
The images stuck in your head (And doesn't that just seem like Rose, that she would try to do this for him?)
Then this:
Of people that you've been before
That you don't want around anymore
They push and shove and won't bend to your will
I'll keep them still (Because of course he has been many different people, many different versions of him, some of whom he really seemed to hate, and she could help him still those thoughts)
And this:
And I'll make you mine, keep you apart
Deep in my heart, separate from the rest
Where I like you the best (Because she'd have to, wouldn't she? She'd have to separate him from Nine and Ten a bit to deal with the situation and deal with the fact that he's the only one who never left her, so she could convince him of this and convince herself).
I'd sure like it if a fic could come out of this. Maybe on the drive down to Portland this weekend I'll give it a go. I need to get my Doctor/Rose mojo back. This song would just make a great vid for them, too, wouldn't it?
