The whole film is about switching the personas of the characters. Adam starts off really reckless…and just angry. Like a loose cannon, essentially. And the doctor starts off really calm and controlled, collected. But the idea is by the end of the film the two of them have swapped characteristics. So the doctor becomes the guy who’s foaming and spitting, and Adam’s the one saying, ‘calm down, we can find a way out of this.’
