This was such an emotionally charged scene and it was so awesome to explore. David and Billie were just superb - especially David. My god - his FACE. I nearly fell off my chair when the Dalek came and arsed everything up because in that moment where they're running to each other...god it was just perfect.

I tell you what, if Rusty had killed Rose I would have been so absolutely gutted. I love Rose! And more to the point the DOCTOR loves Rose! Him being gutted over her death would have completely slain me.
