0:10:36 > 0:10:39The first rule of being interrogated

0:11:22 > 0:11:24There's a storm room in your mind.

0:11:26 > 0:11:28This is my storm room.
0:11:28 > 0:11:32I always imagine that I'm back in my Tardis, showing off,

0:12:07 > 0:12:10Diving into water from a great height is no guarantee of survival.
0:12:11 > 0:12:15I need to know exactly how far I'm going to fall, and how fast.
