In the end I sort of though we created a companion who was so alive and dynamic and so wedded to the doctor that you’d need a whole universe to contain her in.

My God, that scene in Monster Inc. where the monsters realise that their entire world is founded on hurting children -look at that for a change! Two galumphing cartoon characters making a shattering realisation about their world and their role in sustaining it. A truly epic moment. It's stunning.
