“I could see what worked and what didn’t, and I realised how good the kiss was, but equally that the kiss [in a previous draft] had no consequence. That’s why it wasn’t earning its place. But it’s obvious in the end, isn’t it? The scene is about Rose choosing between two Doctors. So, on the last draft, finally, I’ve written clearly, obviously, Rose making that choice. Rose is in control.

The rushes have helped, too.  When Rose is in the TARDIS with Doctor #2, Billie is looking at him with sheer lust. As only Billie can do! That, too, puts the power into Rose’s hands. The mechanics start to work…”
