At least in one sense, we can sympathise with the Doctor. His rebellious companions never learn to abide by the simplest of instructions, namely "Don't wander off!". Anyone with a shred of sense will know not to saunter past the occupants of a Dalek asylum or aimlessly explore the cavernous decks of clockwork men's spaceship, unveiling windows to a French aristocrat's past. Or venture into any perfidious landscape the Doctor materialises within. A distinctive line separates bravery from stupidity, and the Doctor would know this from personal experience. Having to rescue damsels in distress (not excluding Rory) can prove a rigorous task for the ancient Time Lord. Give the (very, very, very, very) old man a break, for once.
