Written for Challenge 117: Improbability at dw100.
Summary: Probabilities arenât set in stone, they change according to circumstances.
The Doctor has long since learned that ‘improbable’ and ‘impossible’ are two very different things. No matter how unlikely something might seem, it’s a very bad idea to rule it out because for some reason, when he’s involved improbable things have a peculiar tendency to become facts, and anything that probably won’t happen almost inevitably does.
The most sensible thing to do is to just assume anything is possible given the right circumstances and that degrees of probability are constantly changing. It won’t help you anticipate the unexpected, but you’ll be better equipped to deal with it when it happens.
